Review: Fast, safe charging with excellent build quality - The Nitecore UMS4 is a fantastic charger. Being able to charge four batteries at once is a huge time saver, and I’ve found that it charges them quickly while giving me confidence that everything is being handled safely. It’s perfect for keeping headlamps, flashlights, and other gear ready to go. The build quality is excellent—solid, reliable, and exactly what I expect from Nitecore. They consistently make great products, and this charger is no exception. If you need a dependable multi‑slot charger, this one delivers.
Review: Easy Return on Investment - This is my second Nitecore charger, the first being the I2. Nitecore products have always been reliable for my battery charging and the digital displays are as informative as they need to be without being overly complex. The UMS4 is a great unit. Having USB C as an input makes it easy to take this charger where I need to without increasing the amount of cables and adapters I already have. The information readouts on the screen help keep tabs on charging progress, total time charging, and when it's time to retire a rechargeable battery that's been in my rotation for too long. So far I've successfully charged AA, 18350, and 18650 batteries with no issue. Similar to a 4-slot toaster, you don't always use the full capacity, but it's very nice to have when you do need it. If you frequently go through batteries, the investment in this charger and a pack of desertcart Basics rechargeables will quickly pay for itself.

### ⭐⭐⭐⭐⭐ Great charger. Use PD charger for best results. I use a 45 watt PD charger.
*by S***W on September 15, 2025*

Great charger that shows voltage, current, resistance and time of charging. I know of no chargers that sense between Li-ion and LiFePO4 batteries, so when charging LiFePO4 (lithium-iron phosphate) batteries, the battery type must be set manually to LiFePO4 or it will overcharge them. LiFePO4 should be charged to 3.7 volts maximum. I cannot understand the negative reviews as this is the best charger I have. I use a 45 watt PD charger with it and it charges four 21700 cells in very reasonable time for Li-ion batteries. A PD charger will give the best results. Note that it charges by monitoring current (CC) at the beginning and charges by monitoring voltage (CV) near the end of the charge cycle. This protects Li-ion and LiFePO4 batteries and charges them to 4.2 volts for Li-ion, or 3.7 volts for LiFePO4 batteries safely.
