Review on 🔋 Versatile 18650 Charger: Smart 2 Bay Li-ion Battery Charger for Multiple Rechargeable Batteries - USB Charger with Universal LCD for 26650, 18500, 17335 & More - Ideal for Flashlights, Headlamps, and Electronics by Robert White

I like that I can charge two different 18650 batteries at the same time and see the charge status of each one individually. There is a button that allows you to charge between half an amp and 1 amp. I understand that 1 amp speeds up charging, but it can also reduce the total charge you can get from the battery. So if I'm not in a hurry I use a half amp charge state. Nice blue LEDs. It also charges other sizes of lithium batteries. The price was very fair. The instructions didn't mention the charge select button. I had to research it. Can't comment on durability yet, so I'm not rating it.
