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… Review: Great project power source - Great project power source Used with a Bluetooth amplifier set up, 30 watt speakers No problem running 4 the day ## Features - Package includes: 1*12V 1200mAh battery pack, 1*12V battery charger. - Battery size: 70*55*20mm (L*W*T),Battery weight about 132g, battery cable length 18cm, 12V charger cable length 90cm. - Premium battery pack: Build in protection board, prevent battery from over-charge, over-discharge, over-voltage and short-circuit.
