need an external battery bank:
External battery power bank supplier
I went out for a short trip in the past two days, where was impossible to get a wall charger to charge my phone, camera and things, hence I thought it'd be really great if I got a solar battery power bank or a compact and practical battery pack charger that can charge my phones especially the camera in the trip days.
Can your guys suggest some external battery chargers good for maybe a short trip? economic if possible.
