Solar Backpack

Max Solar Backpack (Black/Teal)

Recently I acquired a Sun-Plugged Max Solar Backpack. I have had solar powered devices before and never found them to be all that useful beyond anything novel. The Sun-Plugged backpack however has become a resource I use everyday now.

The battery is super light and with the tons of adapters, I can recharge my iphone, my android, or camera.  (Yea, I’m nothing if not armed with electrics.)

This  three compartment backpack features a waterproof, scratch resistant, high efficiency monocrystalline solar panel and acts as a mobile renewable energy power station designed to charge virtually all hand-held electronics. Surprisingly the removable solar cell’s weight is hardly noticeable. Given how fast my smart phone and iPod batteries die, the backpack is a life saver for this techie.

It comes with a variety of plug adapters, and any device that charges with a USB cable can plug directly into the super light-weight recyclable Lithium-ion solar battery.

With a nice look, padded back support, light-weight feel, and good solar battery, I easily give this backpack a 9 out of 10.

Sun-Plugged was founded in 2008 by a group in Monterey, California and has a variety of bags (tote, laptop, messenger) they offer that all have embedded rugged, lightweight, waterproof recyclable solar panels.

The specs on my Max Solar Backpack:

Price: $159.00

The solar panel produces 4.5 watts of power, so 1 hour in direct sun will power over 3 hours of iPod playtime or 1.5 hours of cell phone talk time.
