Hi there. Just small review because i was looking for some advanced device with be honest basic features:ChargingDischargingTestingRepairing as an optionOf course for AA,AAA and 18650 batteries supportGood to have USB type C, but this is really good to haveThis device is on of the best, with wide range batteries type support, different current, auto and manual modes, and indication ;-)Completely understandable indication, with fully independent channels (differenet modes and batteries) suppport.So, really good device which can satisfy beginners and more advanced users.

I got an ever growing collection of Lithium and NiMH batteries, and this gives me a great way to be sure how well they are holding up. I bought this one as it claimed to offer the ability to charge a battery from Zero Volts. I have a collection of these too from a dead battery bank. Sadly not ONE actually started charging, so they should claim it starts batteries from below one volt. Once they hit zero these things don't come back.

Charger recognizes AA Li-ion as 3.70 volts. It shows that the battery is currently at 4.20 volts. The battery is actually at 1.5 volts. The battery an AA Zepath rechargeable 1.5v

My product died within the first year. The customer service is a joke but Amazon takes care of the issue

me facilita ver si mis baterías están en optimas condiciones para cargar y reutilizar en otros componentes electrónicos.

Works ok, but makes a big spark every time I connect the AC plug to the wall, which means is drawing a lot of current, when I mean big spark it makes you afraid, the sound is also scary, most likely is the power supply that came with the unit. Very disappointing,Can’t recommend this producto since is a safety hazard. Sad, I wanted to like this unit.

I would like to add two things to the first review by another customer.1. It appears it is possible so manually set the charge rate for each slot. It's in the manual but it's not very clear. But just go through the standard process of inserting your batteries and select the charge rate. Now switch to the slot you wish to change the rate on and hold the MODE button until "Charge" is blinking. Charging will restart and you can select the charge rate. This should make it possible to select different charge rates for all four slots. What you can't seem to do it mix between auto and manual. It's either one or the other it appears.Again it's in the manual; but comes off more a hidden feature easily missed.2. The LCD backlight will shut off after a short time until you press a button. If one wants to leave it on..long press the slot #1 button when the backlight is on. The backlight will now remain on.
