Bought this power bank in 2009 and recently found it in my old hiking backpack. Once I found a USB mini cable to charge it (mini USB…that’s how old this thing is), it’s back in business.
It’s only 2000 mAh so will only partially charge my phone but it works great with a USB lamp or topping up my Meshtastic node.
Yeah, you’d have thought. I can’t remember the last time I bought a non-rechargable battery except for 9V for my smoke detectors, and none of them were Duracell or Energizer.
Hank green did a bit on as batteries
