XTARVC4 Universal Battery Charger - LCD Display, 4 Slots for 18650 Batteries

Being a die hard Nitecore brand enthusiast for many decades, it great to see other companies that can compete. This XTAR VC4 surprised me when it fully charged a 18650 Battery that my prized Nitecore D4 deemed as a bad battery.. The XTAR VC4 is definitely one of the best chargers on the market in terms of price, quality, durability, craftsmanship, attention to detail, and holds it own against the tried and true more expensive brands in every test.. I highly recommend this charger especially since the USB charging cable can but used in the car as well as home, unlike my more expensive Nitecore that required an additional purchase for car charger. You can't go wrong with either, but I'm starting to think XTAR VC4 is a better product, even though the Nitecore has an over decade long spectacular track record with zero malfunctions or issues!! Thank you for supporting America and it's Armed Forces!!

I have been using a Powerex MH-C9000 Maha for over 10 years and it has been fine. In its day it was considered a very advanced charger. It died a few days ago and I replaced it with the Xtra VC4. Over the last couple years I would throw the batteries that the C9000 said were defective into a bag for later recycling. Turns out this charger can bring them back to life, very nice. Now I am not claiming it brings them back to like new, but many times I need batteries for a clock, or a sensor, not high demand applications. I am thrilled to bring these batteries back into "circulation". I also bought the EBL USB Wall Charger, 5V 2.1A Charger Adapter(Model: M5129) to be used with this since it only comes with a cable and no usb transformer. It seems to work fine and provides the 2.1A needed for fastest charging. I have only used this combination for a few days so cannot say anything about long term durability.I should mention that the first unit I received had one light not working and was promptly replaced by Amazon. Perhaps not ideal build quality but seems to be well designed circuitry.

Charger works like expected. No problem. The only thing I really dont like is this special cable. Why dont they deliver a simple USB-C cable that you can youse any (good) cable? If you loose or break this cable ... what to do?

OK, so I don't know too much about Lithium chargers, so while i think this is a good charger, I'm not an expert in chargers...I bought some 18650 batteries (for flashlights) and tried to charge them in the very, very basic Lithium charger I got included with a flashlight I had previously bought. Despite charging for 8+ hours the charger never showed them as fully charged. When I put the batteries in this charger, it took a couple of hours, but the charger did fully charge them. The weird thing is that when I put the other new batteries (that I never tried to charge in the old charger) in this charger, they fully charged in less time than the others took to finish charging. So it looks like maybe the old charger did something to these batteries.I really like that it has a display and shows me the charge voltage and current. Not that I really know how that relates to the state of the batteries, but it's good to have extra information and watch for anything obviously wrong.I also like that I can charge 4 batteries at once.BTW, I don't know what "sheerness" meant, so i just gave it 3 stars.

I just got it, only time will tell how long it lasts but I believe it comes with one-year warranty. Replacing faulty Nightcore i2. Leaps and bounds ahead, technology, build quality, display, night and day between the two chargers. I've charged two sets and it does not even get remotely hot. Seems to function very well, restoring 4-year-old batteries that could barely hold half a charge, I'll update the outcome. It gives you voltage, capacity. With Amazon and other marketing you have so many options, you're not limited to the smoke shop no name brands that we have all come across. They want just as much as I paid for this and this is a quality charger. I've been vaping for 13 years, so far best charger I have had, Nitecore was great, last 4 years but doesn't give you anywhere near as much information as this charger provides.Update, still running strong after a month. Restored reconditioned two batteries that would not hold a charge. Very impressed. It'd be hard to find a better charger at this price.

This reasonablly priced charger can handle lithium cells as well as nicad. C cell aa and AAA and 18650!I used it to charge 10aaa batteries from new condition, partially charged. I took less than 90 minutes to charge all 10 aa cells. No odd odors or excess heat. Just slightly warm. Meters work well very easy to spot problem batteries. Easy to see how fast they are charging too.

Clear display, nice looking charger.

I bought this because it has a lot of features to tell me the state of the batteries and tells me how many millamp hours it has charged. The charging on the batteries is weird because it chooses to stop charging, saying that it is full but then if you remove the battery and put it back it, it will charge a lot longer. However the reason I am giving it 3 stars is that after just 6 months, it no longer powers on. I am only used it a few times over these 6 months and it would previously turn off unexpectedly, and the problem got worse and worse. I guess there is a bad power supply component - I have tried different 5V wall adapters and cables.
