Fat Shark FSV1816 - Powershark 2 Cell 18650 USB Charger/Power Bank Case

I used two matched Sanyo 2000's that have excellent discharge rates before and after using them in a FatShark. This charger was taken on a backpack trip with an older LG V10, and it only charged at a max of 100mA. And only with the phone off. 2/3 charge took overnight vs. an hour on anyone else's nicer backups.

Over the past few years I've swapped out all my flashlights and lanterns for LED versions that use 18650 batteries. So this device serves a dual purpose. It rides in my truck and keeps a spare set of flashlight batteries charged. Then it goes on trips to charge my phone. I have not yet attempted to fully charge my phone from a depleted state, but when attached, my Moto g6 says "charging rapidly."Edit: After a few months use, I'm knocking off a star. On the positive side, I now use it to power a new LabRadar chronograph and it works well for that. But there are two negatives. One of my lights requires button top batteries and they don't fit without serious force, to the point where I'm afraid I'll break the unit. The second negative is that the micro usb port is a sloppy fit, so that I can't recharge batteries while driving because the cord keeps falling out.

I didn't give this product a five stars rating because the product only charges at 1 AMP when used with a USB Lightning charging cable on the 2 AMP port Otherwise, the product charges at about 1.5AMP to 1.9AMP using a micro USB cable on the 2 AMP port. The 1 AMP port charges at .8 AMP to .98 AMP and takes about 2 hours to fully charge my iPhone 6 from low battery (won't turn on). That is about the same charging time when using a 1 AMP AC (wall charger). Overall, I am very please with this product but time will determine the quality and durability of the device.

This is a great battery bank! Allows one or two 18650 batteries. Has two usb ports; one 1amp and one 2amp. Keep in mind, this does not include batteries! I suggest getting Panasonic 18650 to get the best possible mAH rating from this bank.

I was able to get three full charges on my iPhone X while camping! This device holds two - 18650 batteries NOT INCLUDED and it is a great purchase for that price.

This device doesn’t work at all it doesn’t do anything and the box didn’t contain a cabal as described.Don’t tell me to charge it because I did and it doesn’t work.

Comes without batteries it is unwritten and the batteries cost more than the product itself

As described, easy to mount the batteries. I put 2 X 3.7V 18650 standard & it works very good
