What is Reddit's opinion of KUNCAN 5ft USB 5v to DC 12v Step Up Converter Cable, USB Port Voltage Converter to DC 5.5 x 2.1mm Connector?

From 3.5 billion Reddit comments

My audiologist told me the batteries are incompatible between 6 and 7, so the chargers would probably be too.

Why, why, why, Cochlear?? ...There probably is a technical reason, such as better battery chemistry for higher energy density or somesuch, but dang, say so out-loud if that's the case.

It's a pity for the obvious reasons and also for the un-obvious one that the 6's charger requires a 12V input, which means lugging around a dedicated charger brick ...unless you run standard 5V USB-charger juice through a tiny step-up converter as I did for six years before upgrading to the 7. (A barrel adapter is also needed.) At least eliminating the brick will help you in your backpacking.

I got this step up converter on Sunday.

It's a partial success. It works on half of the USB 3 ports that I tried it on, and it worked with an Anker PowerPort 2 charger. For my needs, that is sufficient. Ymmv.

That charger takes 12V. USB provides 5V. You need one of these to charge via USB: KUNCAN 5ft USB 5v to DC 12v Step Up Converter Cable, USB Port Voltage Converter to DC 5.5 x 2.1mm Connector https://smile.amazon.com/dp/B01ID90K4A/ref=cm_sw_r_cp_api_glt_fabc_9XX0RN71TVFBM63GVWXC?_encoding=UTF8&psc=1 plus a simple barrel-connector adapter. This was my rig for years since I travel constantly (well, I did) and didn’t want to pack a bunch of wall plugs, not to mention my hotel rooms would run out of plugs quickly. A nice multi-outlet USB charging hub (like Anker PowerPort 10 (60W 10-Port... https://www.amazon.com/dp/B00YRYS4T4?ref=ppx_pop_mob_ap_share) let me charge everything I carry.

What was this thing then? https://www.amazon.com/KUNCAN-Converter-Cable-Voltage-2-1mm/dp/B01ID90K4A?th=1

Can’t I use this?

So I was browsing Youtube and came across a guy who created power supply based on two USB power banks in series with two modified USB cables... https://www.youtube.com/watch?v=vNUjy8yqowg

I decided to give it a go myself and splice a couple USB cables together and attach the Garmin power cable, then plug both cables each into a power bank.... and it worked! Though, the reading was 10.2v, which I think is at the lower-end of the spectrum for minimum requirements.

​

I then stumbled across a 5v to 12v step-up USB converter which seemed very interesting and like something that could potentially work here: https://www.amazon.com/KUNCAN-Converter-Cable-Voltage-2-1mm/dp/B01ID90K4A

I'm getting it tomorrow so looking forward to seeing how it works out. If this works out, I think it could make for a very viable solution. I don't know how much real-world run-time I'd be able to get using something like this in conjunction with my 16750mah power bank but that is a lot of juice, so I'm hoping it'll be more than adequate. I see those Nocqua 10ah batteries can run for a really long time (24+hrs?!).

This is what I use for my BMPCC: https://www.amazon.com/gp/product/B01ID90K4A/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1. I plug this into an Anker battery pack (one that would usually charge a smartphone or tablet) and the converter converts the battery pack's output voltage from 5V to 12V. Basically what this is doing is charging your LP-E6 battery continuously while shooting.

It already seemed more technical and EEing than I thought I could handle. My computer has additional USB 2.0 ports and I found something that can increase the voltage from 5V to 12V at the cost of Amps and I looked the specs up for the LCD screen (page 6) and it looks as the max draw is under the 1amp max the step up cable can provide. So I will only need to plug one thing into the wall (my laptop cable) instead of two but have the same number of wires. Does that seem like it would work?

Welp, it is currently working perfectly over just USB using this: https://www.amazon.com/gp/product/B01ID90K4A/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
