Many varieties are available to someone looking at a Solar power backpack.
Portable Power In A Solar Power Backpack
If you are a techie on the go, then you know how frustrating it can be when your iPhone or camera runs out of battery power. If you are not in a place where you can plug in your charger, you are simply out of luck. With a solar power backpack, you never have to worry about that problem again.
There are a variety of different solar power backpacks available on the market today. Some will power all your hand held electronic devices, while a few will work with a laptop or notebook. Most people won’t even notice the built in solar panel, and will simply think you are carrying a backpack, tote or messenger bag with your laptop and camera in it. Of course, you have those devices in it, but the point is that you are carrying around a rechargeable energy source with you at all times.
The solar panel is designed to be scratch resistant and waterproof. Most will come with quite a few different adaptors and anything that uses a USB cable to charge can be directly plugged in without the need for an adaptor in some models. The battery is a very lightweight Lithium-ion solar battery that is designed to be recyclable.
Backpacks such as the Sun-Plugged Max Solar Backpack produce 4.5 watts of power, which means that only 1 hour is needed in the sun for it to power an hour and a half of cell phone calls or 3 hours of iPod use. This backpack is rated for most mobile devices.
The Samsonite Solar Laptop Backpack also generates about 4.5 watts and is designed to power your equipment with a 12v adaptor. The bag is made of recycled fabric so the entire backpack is ‘green.’
As you can see, there are several manufacturers who have joined the solar generation to provide useful ways of taking your power wherever you go, whether it is up the mountainside or up to your 5th story office.
