There are two different types of USB Battery Pack, they are the universal power bank and the solar power bank. The universal power bank is the normal USB Battery Pack portable chargers available in the stores and online. They are charged from the normal USB sources like USB chargers.
The solar power bank, as the name implies is capable of using sunlight to charge up since they have photovoltaic panels. The photovoltaic panels are only able to trickle-charge the internal battery when placed in sunlight because the solar cells are relatively small, but nevertheless, this is a very useful function.
A good USB battery pack is capable of holding a charge for up to 6 months with only a small loss of charge, but lower quality ones may only be able to retain a useful charge for about a month. The USB battery packs are for room temperature, but storing them outside the required room temperatures may considerably reduce their performance.
