Love everything about this product. Didn’t expect it to be this massive though (I’m used to smaller chargers). It took a while to arrive, but that’s pretty much a given when ordering overseas. That being said, TOTALLY worth the wait. The charger has a nice build. It adapts flawlessly to the need of the battery and the display is a very nice ‘finishing touch’ (all the information you need in one place). If all the safety measures are in place (and they say it is) then you can pretty much use any type of usb charger (not included). I’m using the go,comma (gearbest product) and it works nicely. I’m a thorough searcher and I’ve searched a lot of places and all I can say for the price these babies go; (€20) thats a lot of bang for your buck.

What is important in advance, the charger does not have its own power supply, but requires a USB charger (a USB-A to Micro-USB cable is included). In the best case of what dominates at least Quickcharge 2.0. Then the full bandwidth is exploited. You can load the standard AAAA, AAA, AA, C, D with it, but also IMR, Li-ion, LiFePO4 batteries, such as. 14500 or 18650 and many others. Due to the Quickcharge the charger can take up to 9V with 2A = 18W and maximum load with 2x1500mAh or 4x750mAh. The charger automatically adapts to the inserted batteries and loads them optimally. Man can also make manual settings. The display shows the charging voltage, the battery status and much more.

UM4 NITECORE charger is just under their best model UM4+ but I think it will cover all my needs to occasionally charge 2-3 types of batteries. Got it on big discount and so I am very satisfied with my choice charger. The device look big and solid and with very good built quality. It supports wide range of battery types and sizes. Main feature for me is that it connects via micro usb port. I hope it will work fine and charge well when connected via 5V solar panel.

Products description corresponds to actual product. Truly one and only high quality smart rechargable battery charger. This brand Nitecore produces well made, reliable high quality products. Delivery time to Latvia about 2 weeks. Package well packed. All of my recommendations to Chinese manafacturer, seller and distributor.

I've used it to charge 4 Li-Ion 18650 bateries recycled from a laptop battery. Also supports Ni-MH, NiCd, Po-Li etc... So far so good. Device feels robust, display has lot of info. Also has a mode that tries to recover damaged batteries. As a con, you need an external 5V power supply since it only has a micro USB port to get the power, despite it can also be a pro because you can use any old phone charger to power the unit. Overall I'm very happy with it.

Very good and precise charger so you want to charge your batteries quickly. I bought this because my old one needed to stay connected for 15 hours to charge any battery. This charges in less than 3 hours 4 batteries at a single time. I recommend the product, well built and of excellent quality.

Bought this to replace my old one which I had for a very long time. This one is fantastic. Being able to see exactly what each battery is doing is just great. Helps with finding those batteries that are way too gone.
