Review on USB Rechargeable Lithium D Batteries - 1.5V / 4000MAh (2-Pack) - ECO-Friendly & Recyclable - No Memory Effect - Not NI-MH/NI-CD/Alkaline Batteries by Daniel Smith

Revainrating 5 out of 5

Wow, these are neat and already used them multiple times

Saving money. and actually people are mind blown to see it is usb when I show them. Works great in a maglite flashlite , and also worked in a boombox I have no problem. Lasted several hours in the boombox. and the flashlight god knows how long it will go. surely days or more like regular D batteries. I haven't had to replace the flashlight batteries yet.

Pros
  • n/a
Cons
  • Unable to be disposed of in regular household waste
