I normally have a light (PSEQT 4 pods Rock lights) on top to serve as a bright flashlight. The power plug lets me plug in a USB/volt meter (DaierTek 4.2A Rocker dual USB) to charge my phone. This battery is 6 Ah so the light (250 mw) will last more than 20 hours. Long story short - it works. One tip - use Velcro to stick light or USB meter to top of battery, on the same side as the charge lights.
