The Solar Recharger Bag has three built-in solar collectors on one side, and a concealed rechargeable battery ('standby battery') which is recharged by solar energy, from which you can recharge your portable devices with 6 Volt inputs. The bag has a laptop compartment, the separated compartment has padded walls which protects your laptop from impact, scratches, and excessive wear or anything that you would carry in a convenient bag this size. However, do keep in mind, it will not charge a laptop.
When you are not on the move, the rechargeable standby battery can also have energy supplied (topped up) from a car cigarette lighter or from an AC power supply, e.g. a power point.
