A rechargeable power pack is an electronics accessory which is designed to provide a power boost to components like mp3 players, laptops, and so forth. When portable devices are plugged into the power pack, they draw on the pack for power, rather than depleting their own energy reserves, and their running life is prolonged. For people who travel frequently or are often far from a power source, a rechargeable power pack can be a very useful thing to have.
Power packs are meant to be portable, so that they do not add significantly to the load of items being carried. They are also small, and highly compact. Some are designed to work with specific electronics, as in the instance of a power pack which connects with the base of a camera to add more power, while others can work with generic devices, like a power pack with USB ports.
Some manufacturers make rechargeable power packs for their devices as accessories which can be purchased by consumers. The advantage of such power packs is that they are customized for specific devices, delivering the right amount of power and often being associated with warranty coverage. Third party suppliers also make rechargeable power packs which can be used with a variety of devices.
Electronics stores are often a good source for such items, and they can also be purchased through Internet retailers and stores which stock supplies which are designed to enhance mobility, like camping stores. When buying a rechargeable power pack, it is a good idea to look at the recommended energy ratings for the device which the pack will be used with, to confirm that the pack does not produce too much power. It is also possible to buy converters for use with portable power packs and erratic electricity supplies to protect devices from power surges.
When the rechargeable power pack runs down, it can be recharged by being plugged into a source of power such as a wall or car outlet. In some instances, a rechargeable power pack is designed to recharge very quickly, so that little time is lost in the charging process, while others are meant to charge overnight. Most have indicator lights which light up to show the amount of charge which has been completed, and some plug into charging bases which keep statistics about usage and power management, which can be useful for people who like to keep track of these things.
