Abrru battery charger

This works great! I have a battery that I haven't used for more than a year, and it can be recharged very quickly and works normally.

I cannot charge the vaporizer using USB. This charger works very well! ! ! I can now use it for all rechargeable batteries in our home!

The best thing about this charger is the holder/contact-very reliable. Many devices have poor contact, so this is important to me.I like that all chemicals have been specified; I have tried with Li & Ni.I like to have separate channels; some other chargers require two identical batteries at a time.I like the input to be 5V, but I want to use a stronger connector, such as a coaxial cable, instead of USB.I would not call 4-segment displays "high-definition" like they did, but it is enough.
