So you will need to purchase a separate USB power adaptor, or use the one that came with your smartphone. However, EBL does not provide a 10 watt USB power adaptor to actually power this 8-bay lithium-ion battery charger. The 8-bay charger has a 10 watt power input, delivering up to 1.25 watts per bay when fully-loaded with eight batteries, and up to 1.5 watt per bay with fewer batteries. But this is a minor inconvenience – you won’t generally remove the cable unless you are travelling. In 2022, I would have very much preferred a bidirectional USB Type C connector. Power input comes through the very common Type A to micro-USB cable. That “vampire power loss” may seem little, but it is still a waste of power. I would also recommend that you disconnect the charger after use, because it will use up to 0.3 watts of power even when it’s not charging any battery. Trickle-charging lithium-ion batteries is not good for their lifespan. That said, EBL recommends that you take out the batteries once they are fully-charged, and do not leave them in the charger. It is also smart enough to prevent over-charging, over-voltage, over-current and overheating while charging. Please do not use it to recharge your NiCd / NiMH rechargeable batteries!Įvery bay has a separate circuit, allowing for optimal charging according to each battery’s condition. However, please note that this charger only supports lithium-ion rechargeable batteries. It has 8 battery bays, supporting up to eight AA or AAA lithium-ion batteries, or a mix of them. ![]() The EBL 8-Bay lithium-ion charger has a pretty simple design.
