I have this Anker Power Core that I absolutely fucking love.
It's kinda hefty, but sleek and worth the extra weight. Takes about 10 hours to charge, but it can charge your phone 5-7 times depending on which one you get, and the charge does NOT deplete if you leave it in your car. I had it in my car all summer and winter in Michigan for 8 months, and when i took it out, still showed 4/4 lights of charge.
I use mine a lot in hotels and stuff where the plug is too far from the bed, and I also use it a lot at work and stuff like that.
I've had it for 3 years now and it hasn't lost any battery power, PLUS it comes with two USB ports so you can charge two different things at once.
I've been using it to charge my iPhone X and Apple Watch for the last 3 days to test it out and it still has 2/4 power level bars left. Absolutely amazing.
Electricity is power.
Buy yourself one or two of these and revel in ~~the time you can spend on snapchat~~ the ability to avoid shackling yourself to the power strip warlords. It'll charge your phone 3-4 times so you only have to charge it every other day at worst.
Be careful who knows of your power. Someone will approach you every bus ride to try and mooch if your secret gets out. If you're feeling particularly heartless, you could probably charge snacks for time with your battery. The plight of the common pleb is of no concern to you, after all.
To give you an idea this Anker 20100 is well thought of (TheWirecutter likes it and it has great reviews). I picked it up on Prime Day for $30 and thought that was a great deal.
So basically anything around $30 for a decent charger of this size is a pretty solid deal.
rei just had the garmin etrex 30x with 100k US topo bundle for $199 but i'd just bought the etrex 20x, that was a killer deal and worth looking out for if it ever comes around again. My main concern while shopping for a gps (and all electronics i take with me) was the ability to either charge or power via USB. garmin handhelds can power via usb so having large mAh battery backup like this i snagged from amazon for $26 bucks is pretty epic. could go weeks with phone, navigation, music and camera in the wilderness before a recharge :)
I really like anker products. Here is a 20k mah pack but they make all different sizes.
[Most Compact 20000mAh Portable Charger] Anker PowerCore 20100 - Ultra High Capacity Power Bank with Most Powerful 4.8A Output, PowerIQ Technology for iPhone, iPad and Samsung Galaxy and More (Black) [link]
Is anyone else intelligent enough to just use those portable anker battery packs like this? You set it on the couch or table next to you and you literally have endless amounts of power and you retain as much wireless as you need.
I found this Anker on Amazon.ca with 20100 mAh. Looks really good. It has two outputs, so one for the Pi, and I would like to power a monitor with the other one. Any idea how I might power a small monitor with something like this?
I see this one for $40, and a bunch of other options. Will this charger work? [link]
EDIT: Now that I look at it, people say it wont have the power
- I have the Anker 20000mAh battery pack and it has served me well on group trips, recharging headlamps, cameras, phones. It's definitely not light (my scale puts mine at 12.66oz), but I own many Anker products and I can't praise them enough. I don't think you can go wrong with the Anker.
[link] - Heads up there is a newer version of mine I posted above called the Powercore+ but it uses USB-C as the charging input - great if you have a USB-C phone as the cable can be multi-use but it's something to keep in mind.
- As others have said with the technical jargon it's hard to say exactly how many charges you'll get out of it. If you're worried about it, maybe step it up to the next size.
I agree, I'll only be getting more Pokemon flair than the plus bracelet if they have PvP/Trading implemented with the initial release. If anyone finds a minimalist shirt/light jacket let me know.
Gear: Silphroad patch sewn onto my camelback pack, Power Bank, Pokemon Go+, Rollerblades (unless I'm in a downtown area)
I have an Anker 20,000mAh and it was about $40.
I have successfully kept my S5 Active alive for a whole week with it on a cross country trip. The Anker was fully charged before I left and never recharged during the trip.
Anker has cheaper models with less capacity.
I got this monster 20,000mAh for 30$ (now $40) 4k reviews at 4.5 stars. I cant justify anything the sprint post in this thread is offering when compared to this beast even if its on sale only for a short while. I think the highest morphie offers is 12,000mAh
Something worth mentioning is that because of the high RAM usage, as soon as you open another app, Pokémon GO will get closed and you will have to reopen it again. This has been my biggest issue so far. Other than that, battery issues are the same for every other phone. Got this charger (no referral) [link] @$24 deal of the day and it even does "charge rapidly"
Also, the deal of the day has this one if you aren't in a hurry! It is much larger, though. You may want to hold this one in a bag.
I would honestly spend $10 more and get this anker one. link Been using 2 of these since I started playing ingress and they have been perfect. Its not insanely thin but its thin and light enough to where I can put it in my pocket and just forget about it until I need it.
Anker is a really good brand and everyone I know has never had a problem with one of their products. They aren't one of those chinese companies that will just leave you fucked if it breaks. Dropped one of mine once and anker was great about helping me out
I have recently bought this power bank: [link]
I really like it, it's always convenient to have around and it's not too bulky. It can charge my iPhone 6 around 7 times. I've had it for about a month and I recommend it to anyone looking to buy a power bank.
With this, you can be that guy walking around charging yours and your friends phones.
I bought an Anker 20000mAh. It's kind of ridiculous. Was PoGo-ing for around 8 hours on Saturday and for 7 of those hours was plugged into the battery pack. Got home with 100% phone battery and 75% on the battery pack.
E: Oh, and I also bought some new compression shorts.
"This one" It can keep you charged for hours
I have also seen this one that people like. Do you have it, and if so how long have you had it and do you like? What rating would you give it out of 10 being the highest and 0 being the lowest. Also would it be easily portable and would I be able to carry it in my pocket?
There was a sale for Amazon prime yesterday, $30 for a 20,000 mah battery pack (60% off). Picked one up myself, unsure if it's still going on. Will check when I get to my computer.
Edit: Here it is. Seems the sale price has gone up but it's still pretty reasonable (40% off).
It'll be fine on light use, but it has much less capacity (3.4Ah vs. 20Ah = 5.8x more power stored in the 20100) and charges much slower (1A vs. 2.4A -> lipstick-sized charges at about 40% the max speed) than the 20100 that's featured as Amazon's Deal of the Day):
This is one I plan on getting [link] Or any other PowerBar, but has to have at least 10000 mah. A normal phone battery is between 1500-3000 mah
40$ for a 9000 battery is kinda expensive, I just got one for same cost for 20000 mah battery.
Amazon Canada: [link]
Anker is the best charging brand in America
Anker 20000mAh Portable Charger PowerCore 20100 - Ultra High Capacity Power Bank with 4.8A Output, PowerIQ Technology for iPhone, iPad & Samsung Galaxy & More - Black [link]
Amazon's got great prices. I personally went a little extra and paid $40 for an Anker 20,100mAh. Though, you can easily find a 10,000mAh one for $20.
edit: I was talking about USD though. Here's the Amazon Canada link for the one I got. [link]
If you have Amazon Prime, this is a really good deal today.
Hmm, well a portable charger like this one (I just picked the first one I saw, though I've worked with Anker before for giveaways on my YouTube channel and they make good products) is a must have. If I find one of these companies that I can buy stock in I will cause the must be selling like crazy about now. As far as network and gps , I don't have much advice as it's device specific. I can say if you're in an area with wifi networks around that your phone will try to ping to, just turn wifi off cause that's a sure fire way to make the game lag/crash.
There's absolutely 0 item specifications on the page...

For nearly the same price you can just buy this: [link]
Which can charge an i6s/s7 5-6 times, and donate 0.40c to a charity at the same time.
As others mentioned, better stick to quality name brands that will back up their product.
Anker has a 20 000 Mah battery for 42.99$ with usb-C (4.8 A): [link]
You can't go wrong with Ravpower or Anker
Is your Google broken :p
Anker 20000mAh Portable Charger PowerCore 20100 - Ultra High Capacity Power Bank with 4.8A Output, PowerIQ Technology for iPhone, iPad & Samsung Galaxy & More - Black [link]
I just bought this a few weeks ago, because I've been going on lots of camping trips this summer. It works pretty well, it might be a little much if you just want one recharge on a long day. And this sucker is heavy as you might imagine something that's about the size of 8 regular batteries. The fast charging seems to be as fast as the OEM charger and I believe I got about 5-6 full charges plus a few half charges. The biggest issue I see with this thing if you're going to use it often is that it doesn't come with a charger and my 2 amp charger was taking forever to charge. Luckily I have a 3 amp charger that seems to charge it within about 12 hours. [link]
its this one: [link] i can definitely recommend it! charges 2 phones with ease and got enough power to charge them multiple times aswell
This one looks pretty nice, but that price is a little high. Hey, but it's not like it couldn't be used for other things also. looks like a good investment.
I have some rather thick bag, where the touchscreen doesn't respond, when the phone is in it. It's a meshed cloth, so you can still see, if the display is powered on.
It's the bag that came with this powerbank: [link]
Forms a nice little bundle with a perfect fit in your pocket.
Instead of directly charging your phone, have you considered charging an external battery instead? I carry one of these everywhere. At full charge, it can fully recharge my phone several times.
buy a Anker portable charger best thing I ever did, you can charge your surface while its in your backpack. The Anker battery I have can charge my surface four times to full.
Specifically look for ones that promise a certain current output.
I drove two separate strings of 144+16 RGB pixels from this bad boy for several hours.
There is virtually no reason to run things at full current, they're blindingly bright in most cases. I wrote my code so it was easy to tune the final brightness from a potentiometer.
You really only need to worry about separate power tie-ins every couple meters of pixels. If you had one string going 4 meters long, then tie the +5VDC and GND in at the middle and both ends.
It doesn't matter. If you assume the device has something like a 10k mAh battery (which would be very generous considering the size), this would triple the capacity (and battery life for whatever usage pattern):
Can they run off the power of a rechargeable battery like this?
Anker PowerCore 20100 - Ultra High Capacity Power Bank with 4.8A Output, PowerIQ Technology for iPhone, iPad and Samsung Galaxy and More (Black) [link]
Exactly. If you focus on running on time and efficient buses you won't need a USB port because you won't be on the bus long enough to use it.
Also by now I just assume we all have one of these.
Thanks, I'll check that out.
Question - Regarding the wattage. I believe I will need 36 Watts since each meter pulls 18. Would a power bank give me enough power?
I looked at this power bank as an example.
Each port supplies 2.4 amps, assuming I'm only using one, whit would only provide 12 Watts. I have to be missing something or not understanding. Can you help me out?
power banks are nice and anker makes great ones. It depends on the size capcity you want. We don't know what sized battery is in the switch yet so tis hard to know how much tehse can charge.
However the power core 20100 is now smaller. It can charge an ipad air 2 1.5 times
They have them in all sizes and shapes . I wouldn't go to high in costs. $20-$40 is what I would spend. Also you may want to look into 2 smaller batteries instead of one larger one . The one I linked you too will take 10 hours to charge. So it may be a good idea to have 2 and alternate the stress on them and allow for slower charging. Heck you may want to get a 20,000 mah battery pack like I listed and something like a 10,000mah or 8,000 mah . They would be smaller and easier to carry. They wouldn't charge the switch as much but for shorter trips it could be better. Then on really long trips you can take both
in addition to chargers:
power bar(s) -- basically, your hospital room will have plugs all over the place, and rather than charging all your devices all over the room, get a bar.
power bank -- not specifically this one, but something like it... if you're using anything electronic that can be charged via usb, it'll run low on power, and you can shove that in your pocket and not be tethered to an outlet
If you can use a tank bag on your bike, you could hide the battery in there to better protect it from the weather. Then run the charging cable to your GPS unit.
EDIT: I use this in my tank bag for phone charging, which I use for GPS: [link]
I own this charger bank and was wondering if it would work fine with the switch?
Also I know pretty much nothing about USB C cables, so could you recommend me one to use with that bank and the switch? Thanks
I'm not really too knowledgeable when it comes to all of this stuff, but I picked up this powerbank right around when GO came out. [link] Will it have any problems connecting to the Switch? I understand it charges with micro usb but I've used my type-c for my Oneplus 3 and never had a problem getting a good charge from it.
can anyone suggest a specific USB-C to USB cable i can use with a battery pack? The battery pack I have is the Anker powercore 20100 4.8A output. I'm going on a long plane ride this weekend so i'd like to be able to play for as long as i can. Thanks!
It really is mind-bogglingly simple. It was the smartest choice we made on our last trip, hands down! I also got one of these babies and just always had the two in my backpack so I never risked losing internet.
what is your brightness at. I bought this one recently. [link]
and I am trying to figure out if it will maintain a status quo of charge on a switch wihtout too much screen brightness loss (mine hasn't arrived yet) or if I should return it and buy a different one
I wish I could find information on power draw of 1 or 2 phantom powered microphones on the GH5, and for the XLR1 adapter itself. No clue. 10 more days until my XLR1 adapter arrives, though I'm probably not going to fret testing this stuff as I think I'll be ok.
I went for the mentioned Rode NTG4+ shotgun mic with the built in USB chargeable battery (150 hours) that can also be switched to phantom power. This way I have some flexibility if I somehow deplete the microphone battery. It weighs a little more and is slightly longer than the NTG4 but I'd rather deal with those flaws than even be concerned with trying to find out the phantom power draw and having additional battery drain concerns.
Another thought, is I wonder how well attaching a power bank to the panasonic battery charger? I'm not sure if you can charge an active battery over USB-C, but I assume you can charge your offline battery which you can charge in a power bank inside your bags.
I don't have the battery grip but think that if I carry 2-3 charged batteries I should be reasonably covered for what I do. I can always get the grip if it turns into a problem. Sorry if its not terribly helpful that I have rationalized my way around the core questions you are seeking answers to. :)
Tenho um Anker, é excelente e não muito caro. Esse que tenho carrega um iPhone 7 vezes ou um iPad mini 4 vezes. Mas demora 24 horas pra carregar.
Buy a portable battery charger. You can carry that (and a usb cord) around with you and let your phone charge off of it. The largest phone battery I'm aware of it about 5000 mAh (though most are in the 3-4k range), so something like this is at least another 4x battery life: [link]
Hey, I have a question, cause I already own a Powerbank from Anker and I would like to ask you, if it also works: [link]
It is a USB-A Powerbank, and It has 5V=4.8A
Thanks for your help!
EDIT: It supports PowerIQ
Going by the back side of the box it appears to be a Anker PowerCore 20100. You'll most likely be able to use alternatives that full fill those specs (esp. PowerIQ compatibility and output current).
I bought an Anker power bank a year ago that can charge my laptop twice.
I have this one and it charged my Switch while I was playing Zelda once I bought a USB-A to USB-C cable. I think I got it on sale for like $30 about a year ago
Lots of good advise here.
Keep in mind Watts are Watts but amps depend on the voltage. A 10 amp 120V appliance is 1200 watts while a 10 amp 12V appliance is 120 Watts.
I recommend you get 2 of these. One for you and one for your gf. $80 total and usable. [link]
So the next meetup I go to I would really like to show off my backlit keyboards.Is it safe to plug a keyboard into one of these powerbanks?
I don't want to fry them or anything... but there has to be a way to light them up without lugging my laptop to the meet and having it run for 3 hours.
We gave our clients a Anker portable battery for xmas a few years ago. We branded it with our logo
Amazon Link
This was the travel pouch that came with Anker's 20k mAh battery pack ([link]). There are probably other similar sized packs that come with things it will fit in.
So you're looking at about 4-5 hours of hiking a day depending on pace which means you'll have a lot of time in camp to charge your electronics via a solar panel. If you want the solar panel way I'd suggest the Goal Zero Nomad 7 combined with the Flip 20 or you can go the cheaper way and order a an Anker external battery such as this Anker PowerCore 20100 - Ultra High Capacity Power Bank with 4.8A Output, PowerIQ Technology for iPhone, iPad and Samsung Galaxy and More (Black) [link]
You can use a battery pack and ethernet. With Cat6 cable you can do a 100 meter run. This battery should get you about 40 hours of run time. Still way more expensive than the pi itself, but should work.
(the battery estimate is for a zero without wifi, using a usb ethernet adapter, and pi camera)
I've done this since day 1 with my Anker Portable Charger Battery is a beast. Charges in 1 night and can charge my phone + more to full capacity a few times before needing another overnight charge.
HIGHLY Recommend to anyone looking for a GOOD backup battery!! I love it!
Yep, this is the battery pack I have. The battery is easy to hang if you are inside your tent. Especially if it's a smaller battery. Their straps are actually pretty nice. I also do have their 10ft white Luminoodle but it's not dimmable but works well for larger areas
edit: forgot to mention the bag it comes with. you can stick the battery in there and just hang it inside or hang it off a tree or whatever when not inside your tent
Potentially grab a battery pack if you have enough time (might need same day shipping to make it work).
Something like this can recharge your camera a bunch of times if you have USB charging.
> Gift horses' teeth spring to mind.
Hhaaahaa you're right.
Well to go into more detail, this was gifted casually, along the lines of "here you can have this" after they returned from a vacation and used it to charge their phone while traveling. They probably paid $20 (hopefully)
Thanks for the info on how to test, is it reasonable to assume it's only 5,000 - 10,000 mAH ?
I've been wanted to buy this one that's 20,000 mAh for $45 CAD: [link]
A portable battery pack will recharge your phone 3-4x times before it's exhausted.
Anker 20,000mAh is around ~$35 and only weighs 0.78lbs. Easily can be thrown into your backpack or bag and takes up little space. It's almost 2018, you need to step your tech game up.
>charges the iPhone 7 almost seven times, the Galaxy S6 five times or the iPad mini 4 twice.
I keep one of these, an iPhone cable, and a micro-usb cable in my bag
...because everyone has needed their phone charged at some point, and most people don’t want to be with out it.
Edit: fixed link cause /u/YellowishWhite is boss
I have this Anker 20000mah bank: Anker 20000mAh Portable Charger PowerCore 20100 - Ultra High Capacity Power Bank with 4.8A Output, PowerIQ Technology for iPhone, iPad & Samsung Galaxy & More – Black [link]
It doesn’t have USB-c and things I’ve read said it shouldn’t raise the battery level will plugged in and playing Zelda. But, in my experience it does. It raises it by about 1% every 15-20 minutes while playing Zelda. Much faster with the console asleep. Glad I didn’t drop twice as much on the other one people recommended.
Sorry for the confusion. I meant something like this: [link]
That way, it will charge from the portable charger while the car is off, and then the portable charger will charge while the car is on.
I’ve got this guy.
I got it on sale around Black Friday last year. Works just as perfectly as it did when I bought it. I’m that person my friends can count on for an extra charge haha. 10/10 would recommend.
Wife has a 12kmah Anker, and I've got the 20100mah. Mine is slightly larger and heavier than hers, but both are fantastic and worth the weight.
Even charging tablet, phone and multiple camera batteries during the day, I've never drained my powerbank at Disney.
It's a great option for multiple people to use as well.
It does a rapid charge to about 90%, for samsung, and apple products.
A fuel rod, on the other hand, doesn't do a rapid charge, and doesn't have the capacity to do a full charge of any smartphone from the last 3 generations.
Here's my recommendation: [link]
Compared to similar products available in retail outlets, Anker destroys the competitors available at Best Buy, Target and Walmart on price, capacity, and the rapid charge.
Yes, it's more expensive than a fuel rod... but it's useful EVERYWHERE, while a fuel rod specifically is only at it's best at a park that uses their products and you can swap all day long.
Depends. A lot of powerbanks have chips that adjust the amperage based on what the device can handle. This is what I went with - [link] - Although most of Anker's powercore power banks have their "PowerIQ" tech that is designed to moderate flow of power.
I went with that though because it wasn't too expensive and still had solid capacity. There are plenty out there with more capacity.
> I doubt there would be enough usb ports and a sufficient power supply to maintain hours of use with a higher end keyboard and mouse
Why would a keyboard use up much power at all? It shouldn't, no matter how high end it is. Same with the mouse.
All the devices you mentioned should run easily half a day with heavy usage as a minimum by just using a small battery pack made with phones and tablets in mind. For example this Anker power back is enough to power a VR headset (Rift / Vive) with its dual OLED screens, the tracking tech (in case of Rift multiple independent IR LED) and a high quality sound output on top of two independent wireless transceiver (2.4/5ghz and 60ghz) in form of the TPcast wireless solution for around five hours:
Now look at the amount of space in that couch thingy is. You could easily put a few of those batteries in there.

I can't guarantee anything but you'll probably get at least 4 hours from that if you max both ports.

Found this for half the price and same capacity just without PD.
Portable Charger Anker PowerCore 20100mAh - Ultra High Capacity Power Bank with 4.8A Output, External Battery Pack for iPhone, iPad & Samsung Galaxy & More (Black) [link]
What does PD add to the charger?
Well, you have to realize that a pack that takes "all day" to charge is high capacity battery that's going to last a lonnnng time. My 10,000 mah battery takes a few hours with a fast charger - but it's enough to charge my phone 4 times (most take around 2500 mah). A small 2000 mah battery may only take an hour or two but it isn't going to last long - it'll charge a phone about once or a little less.
I find that if I'm careful I can get through the full week on about 2 sets off AAs on lights like that, as log as you're dilligent about turning them off when not on use. On a 10,000 MaH battery, you're probably going to get the full week on a single trips. 1-4 ports - doesn't really matter but if you wanna power two strips, obviously you'll need two ports.
10,000 mah battery might get you through the week on two strips though these days you can get a 20,000 pack for barely more. I'd get that. There's a nice one from anker and you can use it for your phone, too. Link here.. It WILL take a full day to initially charge but you'll get like 8 charges on your phone off of that.
... I'd personally just use AAs though.
I found one one amazon. Is this the same one? If not, which is the better buy? amazon
I just wanted to add that I got the Nintendo Joy-Con Charging Grip and that comes with a USB C to USB A cable that actually charges pretty rapidly - enough that I can play and still have the battery increase. I would say roughly 3 or 4 hours to full charge if asleep, but I have never actually timed it.
I also use this Anker power bank. This past weekend I was in LA with my family and it fully charged our phones (all iPhone 8’s) 5 times and partially charged my sister’s switch before I took it to fully charge my own. After all of that the power bank is still at 50% power.
I fully recommend the official Nintendo USB C to USB A cord (although I am not sure if it is available to purchase independent of the Joy-Con Charging Grip) and the Anker Power Bank (I know they make larger ones with even more charge but the one I linked is honestly more than enough and is the perfect size).
Just my two cents since I was really surprised to read that the OP said it takes 1 hr to charge 10% with USB (and asleep at that) when my switch fully charged in the length of a football game.
Edit: I see now that graphic I was looking at was for in flight outlets, with my Anker I didn’t need those at all.
I was wondering if this was the non-switch version. As far as I can see it is but just want to make sure.
I bought this of Amazon Au:
It was 59 over black Friday, arrived within a few days as it is sold by "Anker Au"
It didn't come with a charge cable, I have been using the one I got with my pro controller for now while I look in what a "proper" charging cable is.
I have no complaints, but to be fair I am waiting till I do a charge cable to do rigorous testing.
Hope this helps.
Hi Streetwalker!
​
12W Apple charger would be okay, however I wouldn't recommend keeping the MYLE plugged in for longer than 40 minutes on that thing, as it's a constant power output.
​
The Battery pack I was referring to (Although this applies to all juice-packs) is this one.
​
As for the information regarding the battery and pod versions, The Juice Punk is the Canadian distributor for the MYLE, so this information is passed on to us through MYLE HQ. Hope that was helpful, and let me know if there's anything else I can help clarify for you. :)
I didn't know this was considered big. Also you can practically stick it right under your couch without having to see the wire or power bank. Those things are absolute gimmicky, you could buy a similarly priced couch that has better quality that doesn't have a usb charger.
Hey there! Personally, I use this Anker PowerCore 20100mAh power bank, and it definitely gets the job done. I personally use an S9+, and while I usually do IRL streams for 2-4 hours I don't run into power problems. The charge on the bank could easily charge my phone completely 3-4 times over. As for the mic, I can't help you there as I don't use one, but I'm very curious to see what kind of recommendations you get for that so I'll stay tuned. Good luck!
I used this one last year :) it lasted the whole weekend! It's pretty big but it has so much power it was worth it! Just remember to charge the portable battery pack beforehand haha
