I use this almost every day and it's very light weight and easy to use. It does not have an amperage guage so if you're looking to switch between 0.5 and 1.0A then this isn't for you.This also does not have a digital screen to show how much your batteries have charged. It will show a light at the top that starts red with an uncharged battery and turns green when it's finished charging.Overall, if you want your batteries charged this will do the job.

I used this to charge a new pair of 3200mA-hr 18650 Lithium Ion batteries over night. The initial voltage was 3.7V and the final voltage was 4.26V. I used the power supply for a Raspberry Pi to provide the energy to recharge the batteries, since it didn’t come with a wall adapter. It worked.

Does just as expected. It is exactly what I ordered and functions just as expected. Good purchase

Tried charging when delivered and worked alright. Made of cheap plastic but price was ok.

Works great just seems kinda cheap. But works ok.

Does exactly what I needed. I think I like that this one isnt complex like my old one. It doesn't seem particularly well-made but it also doesnt seem like it will break for no reason.

Super nice charger. Comes in handy for when you don't feel like charging up every day. Sometimes I can go days without charging depending on my use - im a regular user too. Highly recommend

It works fine to change my batteries. One thing I didn’t like was if I put a battery on the left side without a battery on the right side it wouldn’t charge.
