My original power center has worked well. Run times have been a bit under 8 hours powering two lights. I'm using this power center for my cell phone and ipad and as back-up for the one that came with my light kit.

I purchased this battery to have as a spare for my light kit. It a little pricey, but the quality is there and it works well. Both my batteries are getting around 7.5 hours running 2 lights. The USB charging port is a nice feature....charges my iphone without breaking a sweat.

Charges quickly, very handy for our tradeshow booths.
