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.

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.

I found the XTAR VX4 by searching for a charger that could be powered by a USB-C PD power adapter (Note: It requires a power adapter that supports 12V1.67A to take advantage of PD. Several popular USB-C PD power adapters do not support 12V). Alternatively, it can fall back to QC3.0 (9V2A) or 5V2A). I ultimately purchased this charger to grade batteries, as the marketing states it is > 95% accurate compared to lab grade testing equipment. However, while attempting to grade batteries, the charger keeps resetting. I put the charger into "Grad." mode, insert the batteries, the type is detected automatically and the batteries begin to charge, then, after charging completes, they begin to discharge, showing a flashing mAh rating as they are graded. However, when I come to check if grading is complete (it can take all day to grade higher capacity batteries), the charger is in "CHG" mode showing all batteries fully charged, with no final grading information. This has happened multiple times with Ni-MH batteries and most often with older eneloop AAAs. This has happened using both the included power adapter and cable, as well as using an alternate USB-C PD power adapter and cable. I am going to exchange the unit I received and will update this review if the replacement works as expected.EDIT: The replacement unit has not had the problem described above. I’ve completed grading multiple sets of AAAs, including two sets where I experienced the above issue with the original charger. Increasing my rating from 3 to 4 stars.

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!
