18650 Charger XTAR VC4H Battery Charger 4 Bays Updated 21700 Battery Charger USB C Charger Not Including Batteries

Works great, gives info staus on screen.

I keep this on my desk and use it to recharge a variety of batteries for flashlights and battery packs. It's simple and easy to use, the screen tells me when it's charging and when the batteries are done charging. I don't know what else to say about it, works good, not too expensive. If you need to charge several batteries at once, this is the way to go.

The device works as intended but the unit is not designed to work with standard USB C pinned cables. What this means is if you lose the detachable USB Cable that comes with it, you can not just replace it with any USB C to USB A cable you have. This also means the the USB C power supply I had intended to use with this unit will not work as you are forced to use the included USB C to USB A cable. This is kind of misleading but unfortunately it does use a USB C port on the device so it is technically correct. ======UPDATE====== After testing out several combinations of cables and adapters I have discovered that this device does function on standard USB C to USB C cables and USB C to USB A cables. It just would not function on the specific combination of cable and adapter I had tried it on. To clarify, I have tons of USB cables of different types of varying quality levels, the ones I originally used are ones that are rated to charge up to 100w of power and are also rated to use USB 3.2 high speed data transfer. So when they did not work to power this device I pointed a finger at the device. After swapping out the power adapter the device worked as intended. But weirdly when I swapped out the cable for another brand using the original power brick it also worked. So YMMV depending on what power brick you have and what cable you have as to weather or not this device will work. This all based on you losing the original cable because that never failed to power on the device no matter what I plugged it into. Updating to 5 stars.

Awesome, was able to charge batteries that my Duracell charger couldn’t revive. Nice to see the charging level as well. Great buy and you won’t be disappointed

Quick Charger.

AMAZING for the price! Very happy :)

Not expensive or super high quality charger. It will 1 amp charge a NiMH in one slot, if you charge 2-4 you only get 0.5 amp charging even though it's a 2 amp charger. 1 amp charging is actually good for the batteries and faster so it's disappointing it won't charge 2 at one amp. It charges all the batteries I have put in it fine. It has a display that tells you what it is doing and gives some idea of battery capacity. I recommend it at the price. I just wish it would charge 2 NiMH batteries at 1 amp, then I would give it 5 stars. It's scarcely more expensive than a 2 slot charger but I mostly use just one slot and if you don't have a lot of batteries or are space limited, I would buy the two slot because fast charging one battery at a time is as fast as charging 2 batteries slow. Charging at 0.5 amps is slow and doesn't really protect the batteries because no harm is done at 1 amp charging but at 0.5 amp charging, NiMH batteries won't live up to their full potential. Lithium ion batteries are fine at 0.5 amp, though it's slow. Good charger at the price.

Bought this for an assorted bag of 21700, 18650, 14500, and NiMH AA/AAA. Charges efficiently and does so with mixed types of batteries on it.
