At the moment, there are several mobile phone chargers that can replace the standard one that came with your cell phone. You can now recharge your phones without any wires, with the help of a portable charger and soon enough all mobiles will come with a standard USB port that can be used for charging.

You can also recharge your phone with the help of a solar mobile charger, and Off-Grid Systems provides another way to do that by presenting the Sunbag S, that comes in three different varieties, a wallet, carry pouch and backpack, in order to suit the needs of any user.

The product ensures that the mobile phone recharges via solar power and targets people who are always on the go. Therefore, even though the users are far away from any power source, with the help of the Sunbag S, enough power to charge mobile phones or other portable devices will be provided.

It includes a long-lasting lithium-polymer battery that can charge most electronic devices and the list of compatible mobile phones includes Sony Ericsson's P800 and P900, as well as the Z, T and R series, several Motorola models including the V3 and all Nokia mobile phones.

Apart from that, it can also be used for charging your iPod or GPS. The battery can also be used as a spare battery when the user removes it from the rucksack, carry pouch or solar cell wallet.

The Sunbag S can be purchased for around $145 (which is kind of a lot for a charger), with the adapters that the innovative charger comes with included in the price.
