Charge/charge lights change from red to green but very dim

Seems to be working well. The LEDs used for charge/charging indicators change from red to green when charging is complete. LEDs are very dim. When I first plugged it in I thought it wouldn't work until I turned off the light on my desktop. The indicators are not visible outside or inside the vehicle.

Pros
  • Overall performance is excellent
Cons
  • Doubtful

Nice concept when it works

I like the fact that it's small and easy to use, but one or more of the ports doesn't charge. I thought maybe I had a bad one so I ordered another one and sent the first one back and when I got the second one I had the same problem with a different port. Maybe I'm doing something wrong but 2 of my batteries didn't charge while the other 2 charged. It's cheap and I think you get what you pay for.

Pros
  • Great for me
Cons
  • No instructions

It's good. The top-up for 8 slots is also good.

I'm charging a Revain Basics AA 2400mAh battery. After 10 minutes of charging, my Keweisi USB meter shows that 75 mAh went to the Revain battery. The charger seems fine. I like the small size. USB charging becomes very convenient. I would recommend not charging batteries with two different brands of chargers as the batteries will end up draining at different rates.

Pros
  • Decent performance
Cons
  • Miscellaneous Miscellaneous
