Review on 🔋 Tenergy TN471U Universal Battery Charger: LCD, Li-ion/NiMH/NiCD, Micro USB Input, Portable - 18650, 16340, 26650, AA, AAA and More by Allison Smith

I have bought several of these 'fancy' chargers from various manufacturers over the years and have had no luck. The display will usually turn off first and the charge capability will ramp up and down, then turn off shortly after. This unit has been running trouble free for several weeks. I use a lot, 18650, 14500, 10440 lithium almost daily. I haven't used the Nimh feature yet because I haven't used it in years, but I'm thinking of getting a few. So, apart from one unforeseen explosion, this device is fast, no weird noises, which I can recommend with confidence.
