XTARVX4 Visible Mixer 1.5V/3.6V/3.7V Li-Ion 3.2V LiFePO4 1.2V Ni-MH Batteries Charger and Battery Capacity Tester

Very useful and versatile charger. Gives technical data as the battery charges more suitable for the tech minded person.

Get this one. This is the one you want. This is the one you need. This is the one you will love! This may be the best battery charger/analyzer/battery recovery tool available on the planet. Great user interface, well built, versatile type-c input, high power charging capabilities and it will handle virtually all of your cylindrical device batteries, including 1.5 volt lithium ion batteries! The long spring loaded slots will accept very large lithium ion cells that are becoming increasingly popular. Get this one.

Great quality. Easy to use.

This device can charge and test a variety of batteries, but I have found some AA and AAA lithium ion batteries that are not compatible. When I put them on, they read voltage much higher than they should and the charger thinks they are different than they are.User interface isn't fantastic, and button feel is really bad and cheap. Feel like they will break with every press. Functions are hidden behind unintuitive long presses.You have the option for 250, 500, and 1000mA charge/discharge.

Finally one charger for all my battery types. I have a mix of Li-iON, Ni-MH and I always wanted a smart charger that will first check for health and then charge. I also used once the discharge/cycle feature to check capacity. I really like this charger. I have been using 2-3 times a week for months. No issues.

Love this charger I have the Dragon that won’t do AA-AAA LI-ion nice addition I should be good for a few yrs only thing is change change charging amp on 1-4 bays it’s locked ,

Good charger for the Li-on AA/AAA battery's. No complaint's so far.

Product works as advertised!
