Review on Smiling Shark LCD Universal Battery Charger: High-Speed 4 Bay Smart Charger for 18650, Ni-MH, Li-ion, AA, AAA and more by Ian Patilla

I'm not even sure if they make rechargeable batteries these days, but this thing is adaptable enough to handle anything. I've long been accustomed to USB powered chargers; I have enough extra batteries, I don't need a faster charger. This one does the job. It's a little confusing at first to see the lights bouncing around, but they eventually calm down and show where the charge is. The only thing I can say is that it appears larger than it should be. I have no idea why the battery compartments are up to 3 inches long. I don't have batteries longer than 2 inches.
