Security
Been using this for months now. It stops charging when full, batteries are never warm. I've charged 14500, 18650, and 20700 without issue. A reliable little unit.
This was my first dedicated li-ion charger. Easy to understand, just insert and charge. It brought a dead 18650 back to life that my old charger couldn't. USB makes it portable.
I use it exclusively for 18650 cells. One slot charges a bit faster than the other but that's minor. The LED is bright and shows status clearly. Good value.
Exactly what I needed. The 2-bay design is perfect for my small desk. USB input means I can use my phone brick. The sliding contacts are smooth, holds cells tight.
I like that I can put a 18650 and a 14500 in at the same time. The auto-detection works well. No overcharging so far. A great universal travel charger.
