iCreatiniCreatin 8.4V 1A Power Adapter Li-ion Battery Charger with LED Indicator 2.1x5.5mm Interface Suitable for 7.2V 7.4V 8.4V 2-String Lithium Battery Pack

I bought this in January of 2023 worked perfect ever since. I saw a some negative reviews on this item. Those were user problems, not product problems, I am an electronics technician. This works great in any two lithium ion cell charging applications. In some case the plug connector will not fit other sockets, that's not the fault of the charger.

I purchased this as a replacement for a bicycle headlight charger that broke. Before buying, I was careful to check the plug sizes and the voltage rating of the device and make sure it matches the old charger. This charger works great at charging up the battery concerned. I am completely satisfied.

I lost my charger for my Bubba Knife. Took a chance and bought this one to replace it. Luckily it worked.

The first time I plugged this charger into my 8.4 V battery, the green light came on, suggesting the battery was already charged.Problem is, I had been running the battery for over a month without charging it, so I knew it was not fully charged.I unplugged the charger, plugged it back in a few times, and eventually the red light came on, suggesting the battery was in need of charging and that the charger was doing its job.I let the charger sit on the battery overnight, and in the morning the light was green. I figured everything was great, but found out I was wrong when I tried to use the 8.4 V battery the next day.Now the battery is completely dead and the charger will not charge it.

Charges my bike light battery with no problem

I found this older camera at the pawn store but I couldn't see if it worked or not, one there was no charger, so with this I was able to charge the camera and it works fine now

Great product and goodPrice

Was hoping this would fit my dad's heated knee massager, it didn't.
