I’m sorry, but I LOVE this battery…
Reviewed in the United States on July 6, 2025
Style: 1.2Ah DC5521 plugVerified Purchase
I’m sorry, but I love this battery. Charges pretty quickly, but lasts a long time, a little “pricy” for my model building budget. I originally bought this battery to power the Arduino in my (self printed) 1/1000 Crossfield Class Federation Starship. But I liked playing with it so much I have yet to close up my U.S.S. Discovery. Our neighborhoods power went out for three days. I took this battery, about 100 leds and lit up our (above averaged sized) front room. We had three nights with the kids and my mother-in-law playing games, doing puzzles or even just talking. I still wish I had a generator though, so don’t go thinking you can power your refrigerator with this. But if you are thinking that chances are you can’t read anyway so…
