Review on Rechargeable 12V 3000MAh Lithium Battery Pack: Power Bank For LED Strip, CCTV Camera & More by Owen Blanco

Been running a mini fan for camping trip for 7 hours straight and it still shows only a 20% drain. Powers my portable record player on USB mode which uses barely any power and the battery hasn't shut down at all while playing music because it uses an on-off switch! Previous battery would shutdown because of the lack of amperage/load. Now I can play music really low and not worry about the battery going to sleep. Solves my problems. So far, so good; hope it lasts atleast 3 yrs. Store it in an ammo can just in case it decides to burn up to prevent fires. Can never be to cautious with Chinese batteries.
