XTAR21700 Battery Charger VC2L 18650 Charger 2 Slot 2025 Version with LCD Display Max 2A Rechargeable Liion and AA Charger Not Included Any Batteries(VC2L)

If you're looking for a fast and efficient two slot charger, this is a great choice. I mostly charge 21700 at 2A, and they stay nice and cool the entire charge. The sliders are nice and smooth and are easily extended. The display is pretty basic in info, but looks good and gives you sufficient info on your charging status. The only ding I would give it is the lack of rubber feet for surface grip. I did have to add my own, but not at all a deal breaker. Definitely recommended.

Would definitely recommend for a faster travel charger.

This charger helped me revive a couple solar lights by recharging their almost dead batteries in winter. The batteries come in different sizes and chemical composition from Ni-MH to lithium iron polymer something something. Currency is adjustable, so I keep it at the minimum possible setting (0.5A most often times).Couple things: There is only USB-C inlet. If your Ni-MH battery is at the end of its lifetime, it will not charge. You have better luck with older, non-smart chargers. Also some of my quite new Ni-MH batteries sometimes black-out. They don't accept charge on this charger. They need an old fashion charger to pick up some charge before acting normal. So, this one fails to revive those batteries. I noticed the left side finishes charging earlier than the right side and puts less energy into the battery when two identical batteries are charged in parallel starting at the same time. That's a little puzzling. Overall fine.

Does what I wanted. Charges batteries. As for readings I'm not concerned with the accuracy. If you want accuracy the you will have to pay a lot more. You get what you pay for

Just as described had it a few weeks no problems with it at all.

Great item to use.

using for few months with no problems on my li-ions.....so far product worked as described including reverse polarity.china made getting better ! thank you !

Amazon will not allow return, charger will only charge in channel 2 after a week of use! Buyer beware!!!
