No box or instructions

This charger arrived in a box with several other items I had ordered from Revain. It didn't have its own packaging. It was not in the box and was not sealed. There were no documents or instructions. It looked like it was just thrown in a box with other items after the fact. It looks and feels cheap, I wouldn't order it again.

Pros
  • Smart charger
Cons
  • Can't remember

Pretty decent USB charger

Somehow I misunderstood that this charger also comes with an AC plug. This is not the case and the only power source is the USB cable. Fortunately, I have already bought 3 packs of USB charging adapters. Works perfectly! I ripped apart a "dead" laptop battery only to find that I had 8 perfectly healthy 18650 cells inside. It only took a few hours to charge all of them, 4 at a time, and now they're all measuring 4.0-4.2V.

Pros
  • security
Cons
  • boring packaging

Works well for the price.

This charger offers good performance for the price but is not, nor does it claim to be, a fast charger. It's worth noting that the USB port is the only charging option, and if that part bends at all, the charger will fail and become unusable. This part of the USB is VERY thin and can easily be bent. If you plan to keep this charger on your desk or bedside table, it works perfectly. A full charge takes around 6-8 hours but if you plug it in before bed you will wake up with 4 fully charged…

Pros
  • Universal USB port
Cons
  • Only available in white
