What can I charge with a mobile power supply?

These battery packs can power almost any device, from your smartphone and tablet to laptops and portable gaming consoles. However, they are primarily intended for portable media and communication devices. Examples include: smartphones, tablets, portable speakers, wireless headphones and small cameras.

 

Size, shape, weight and capacity are the main factors to consider when buying a mobile power supply. A clear indication of available power is also useful, with some models showing a digital display rather than a bar (e.g. "80% remaining").

Size and weight

Size and weight typically increase as the mAh capacity increases. While the 20,000mAh model seems like a convenient choice, it may be too big for your pocket or bag.

If you want to charge your phone for a day-long music festival, picnic or night out, consider a pocket model with at least 6,000-10,000 mAh. Other situations, such as hiking trips that leave you disconnected for several days, may require larger models, but these are usually too large for most pockets.

How to purchase the best mobile power

  What capacity do I need? Capacity, expressed in milliamp hours (mAh), is a rough indication of charging capacity. The higher the number, the more power it can provide to your device before the mobile power source runs out of juice.

Mobile power can range from a single charge (3,000mAh) to well over (20,000mAh), with most of the latest smartphones having a battery capacity of about 3,000mAh. a 10,000mAh mobile power should be able to charge your smartphone 3 times, while a 20,000mAh mobile power should be able to charge your smartphone more than 6 times.   How long does it take for a mobile power to charge my device?
