How many will it charge at a time?
Hi there.It seems to be charging ok, but the blue lights only go up and down to 4 on the level and 1 green light. If i put more than 2batteries in( 18650) batteries, then the 3 green lights and the 4 blue lights flash continually, and i don't think there charging if you put more than 2 in because of this. As i checked when all the lights were flashing the 1st time i used it and don't think they were charging. So looks like the type i use you can only put 2 in at a time, to know for definite that there charging. If all 4 would flash the way it should when you put 2 in, then it would be 5star. But I'll see how it goes, as i might be able to live with that. But obviously it should charge 4batteries of the 18650 type i use instead of 2 at a time.

Capable of charging 4 18650 batteries at the time. Easy to use.
I have used it for charging 18650 batteries. I provide it with 5V 2A and set the charger to the lowest charge power and it charges the batteries to their full capacity. The battery level indicator is better than a single charged/not charged LED on some other battery chargers. It does feel a bit light and cheap, but does exactly as required from it.

Junk
I got the 2 gang one, which is good but having got 16 batteries I needed more space. This does the new 20700 etc.In 12 weeks one of the charge lanes stopped working. Piece of junk. Don't buy
