A camping battery pack normally is known by the name backup power station since it can supply power to multiple electrical devices at the same time. It can power a portable computer, cell phone, flashlight, a personal alarm clock, a personal digital assistant (PDA), a GPS device, and an ipod. The size of the pack may vary according to the requirements of the user or the size of the device to be powered. Most of the modern battery packs are capable of supplying sufficient current to run all these devices simultaneously. Different models likewise have different ports and outputs for different common types of electrical devices: DC 12V, 6 mm, and 120 V AC.
Why need Camping Battery Pack
There are certain things to be taken note before buying a new camping battery pack. First of all, the capacity of the batteries is an important consideration. Li-polymer and lithium polymer (or Li-ion) batteries are considered to be the safest for camping purposes as they are less susceptible to damage compared to lead-acid batteries and do not produce toxic gases during discharging and recharging. However, Li-ion and Li-polymer batteries are slowly being replaced by other batteries such as nickel-metal hydride, lithium polymer, etc. They may have slightly higher discharge rates but give a longer lasting life. Nickel cadmium and nickel zinc are also gaining popularity as substitute materials for Li-ion batteries.
Other important considerations are the type of connection used for power and charging, the compatibility of the battery management system, and the expected amount of use. Fast charging and fast discharges are necessary when using a CPAP machine in order to use it while camping. A fast charging system generally is intended for overnight usage while a fast discharging system can be used over a period of time, depending on the amount of CPAP users and the needs. It is recommended that one purchases a power and charging system that are compatible with the brand of CPAP used in the device.
