Seems to charge at about 4kW (guessing), and hopefully should work with a Spark EV too
I have this two:

Both works fine with AbetterRouterPlanner, MyGeenVolt and Torque Pro
I got Achilles ATR Sport fronts (185/55r15) and Achilles ATR Sport 2 rears (195/55r15).
They were the cheapest on Amazon at $50/each when I bought them and they have exceptional wet and dry handling! I do not get snow where I live so I was after maximum grip. They handle much better than the Ecopias but did cost some range.
Ultimately anything plugged electrically to the car will use your battery range.
Because as far as I know, the 12V battery is charged from the traction battery pack. It's probably LESS efficient to run accessories from a 12V since the inverter has to convert 300+V DC to 12V DC to charge the 12V lead-acid battery which results in a % loss of power along the way. But of course, automotive accessories are only manufactured in 12V compatibility so we need that 12V battery too.
If you want a way to cool your phone without affecting your range at all, invest in a fan something like this that can plug into the charge port of your phone, then point the fan at the back/front.
Or maybe a battery powered fan you can point at it (and possibly yourself as well).
Also - keep the phone out of direct sunlight. Just having it in a shady spot with open air flow should keep it cool enough. Direct sunlight with high UV can overheat a phone in minutes.
Seems a little extreme to be honest, unless you absolutely need the range to make it home in a day. If it is hot enough to ruin the battery in your phone then you should probably just run your AC. If you want to conserve, close all the vents except one and put your phone on that one and then just run the AC on low.
If you are determined to run a separate cooler. Something like this might work.
I bought the Bafx Products one on Amazon, it's a bit on the pricer side at 22 Dollars but the reviews stood out to me and it was an Amazon choice product so it was kind of a no brainier purchase to me. It's been a great purchase and I've had no problems with it, would highly recommend.

The Juicebox is a great value, and it is built like a tank.
The RMA unit is sealed in the box. They took a couple weeks to decide if the lightening/surge damage was going to be covered under warranty, and I drive the full range of my car every day without enough charge time for my L1 to completely charge me, so I ordered the Juicebox to get back up and running. They ultimately came through with the replacement, but I havent been that interested in tearing the Juicebox off of the wall since it gets the job done. My Chargepoint is the hardwire model, and you would have to add the 18 or 25ft cable, depending on what you need (https://www.amazon.com/dp/B00YJFHF8M/ref=cm_sw_r_cp_apa_i_z6FyCb51HV3E5), so I would do like $250 for it. If you bought the 25ft cable on Amazon for $280 that would be $530 vs the $700 that combination retails for.
