- XTAR VC4 Universal Battery Charger - LCD Display, 4 Slots for 18650 Batteries

This is awesome! I purchased a new charger because I thought my old one wasn’t working correctly. Every-time I’d recharge my batteries, they would drain so quickly. So, I pop my batteries in to this new one and I’m shocked to find out it was my batteries. It shows you voltage and everything. The awesome part is that it revived the real over used and old ones. Also the charging is very quick. Now my old batteries seem to be working almost like new again.

Absolutely LOVE this battery charger!!!! The info is all right there. Exactly what you need, and it stays lit up looking cool as heck as long as its plugged in. You know those generic pictures of a hacker wearing a black hoodie, with a Matrix screensaver... Yeah. that guy needs one of these battery testers on his desk to look cooler....

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!!

The pros: - Love the detailed display and option to turn on the backlight for better visibility! It even tells you the type of battery tech charging in each slot! - LOVE the versatility! This thing charges all kinds of batteries including lithium ion! Generally speaking, if it looks like anything from aaa up to D size, this thing will charge it. It even charges my vape batteries which is huge bonus! Cons: - proprietary USB charger so if you lose the cord it becomes a paper weight. - D size batteries need to be held down. I used rubber bands and it worked well.

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.

This is a first impression review as I've only had this about 48 hours so here goes. First off, I was a bit worried about counterfeit items as I've heard that's possible but there's a label on the box with a scratch off that you can enter at xtar.cc and confirm that it is their product which is cool. I use 18650 batteries for my vape mods and also flashlights but this will also work with most all rechargeable batteries. I had about eight 18650 batteries that I had marked with a 'D' (for dead) in sharpie because my vape mod wouldn't charge them anymore. As others have said, this charger can bring batteries back to life, they are all (so far) now again completely useable! I also completely charged up some very old Panasonic enloop AA batteries. I couldn't be happier with my purchase! It feels sturdy and well made and the display is very well thought out and informative. I highly recommend this product! Xtar chargers are way past cool!

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.

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.
