Review on Ultra-Fast 18650 Battery Charger by MiBOXER - 3A/Bay Rapid Charging for AA AAA D 26650 18490 18350 18500 RCR123 Li-ion/IMR/INR/ICR/Ni-MH/Ni-Cd - LCD Display, Intelligent Temperature Control by Tatiane White

After buying a pair of flashlights with 21700 batteries, it was time to get a charger that could work with those batteries. Although the flashlight has a charging function, I prefer to have a spare set of charged batteries. This charger can charge Tiny & Skinny 10340, 10350 and 10440 cylindrical lithium-ion batteries up to the thickest and longest 21700 Button Top and 26650 (yes, including RCR123a / 16340 batteries). It also charges conventional NiCd and NiMH rechargeable batteries: A, AA, AAA, AAAA, C, SC and DA. It worked fine for several weeks. By searching you will find lithium ion electronics professionals who have tested and analyzed every aspect of this and other chargers. Let's just say the wizards aren't exactly against it. ;- }Is it the fastest? I do not know. In real applications it is not easy to find two batteries in the same condition to compare with this and one of my other chargers. As I said, I have this to meet all my charging needs. I'm still learning about the information this charger offers. Note. It may be useful to remember to leave the batteries in the charger for a long time after they are fully charged.
