The Solar BackPack is fast becoming a must have item for gadget lovers and Eco warriors alike.  It is not surprising when recharging all our personal electronic items can be done for free, with purely renewable solar energy.  One of the most popular models is the Voltaic Solar BackPack which is reviewed below.

The Voltaic Solar BackPack

Okay, first and foremost this is a sturdy backpack.  It is tough enough to take hiking, with plenty of space and sturdy pockets to hold just about everything you could need.  It contains around 1,850 cubic inches of storage space.  The dimensions of the backpack are 15 x 10 x 20 inches.  Coming in at 3.5 pounds it is lightweight enough for use hiking or as a regular school or college back too.

Crucially though, the Voltaic back pack comes with three solar panels to collect solar energy.  This energy is converted into electricity that can either be stored for later use, or used immediately to charge your mobile electronics.  The solar panels generate up to 4 watts of power which is enough to cope with mobile phones, PDAs, blackberries and so on.

If you do not need to use the electricity for charging electronics immediately it can be stored in the 2,200mAh battery.  This makes the Voltaic far more versatile than many of its competitors.  Storing solar energy is critical if you always want the facility to emergency charge your personal electronics.

In a bid to make this even more environmentally friendly the Voltaic Solar Back Pack is made from recycled soda bottles.  Could this thing get any greener?

Versatility is probably the Voltaic BackPack’s middle name.  It can also be used when the sun is not forthcoming.  The battery can be charged from a car charger or from a household electric supply.  This means you can keep the battery charged prior to long excursions when you really would not want to run out of power, no matter what the weather.

The Voltaic Solar Backpack is supplied with a range of adaptors for charging various items but of course will not have one for everything.   Before buying it makes sense to email the supplier and check whether you will need additional charges.  Also, though this is a relatively powerful model it will not charge high power items such as laptops so it pays to check the power rating of the gadgets you really want to recharge regularly before making your purchase.
