Portable Chargers and Battery Packs for Mobile phones and Laptops
A portable power pack or power supply is a useful addition to any good portable solar power kit.
Some are designed to be used specifically with a certain solar kit, like the Powergorilla and Solargorilla, but they all can be charged from any other power source like an wall power point, USB port or a standard solar charger.

Most battery packs use Li-Ion Batteries
Li-Ion batteries are light yet powerful, so are used in portable battery packs and solar chargers. In addition to great power to weight ratios they are eco friendly because they do not contain any hazardous metals like lead or cadmium.

LI-Ion batteries do not have a charging memory
Another great improvement of Li-Ion batteries is that they do not need to be fully discharged like the Ni-cads as they don't suffer from the memory effect, where a battery can't be fully recharged if they are repeatedly recharged after being only partially discharged. Lithium ion cells will always fully recharge.

LI-ION Batteries hold their charge longer
Most batteries will go flat even when not used but Li-Ions will last 3 to 4 times longer than older types so they are suitable for use in emergency backup chargers and lights.
There are many great advances being made in battery technology and we can expect power to weight ratios dropping and shelf life being extended to provide better, smaller, more compact power packs.
