Top 3 Portable Power Banks for all Your Needs – Don’t Lose Charge

More Power To Take You Further

With our increasing use of battery powered equipment and a need for charging on the move, power banks, or portable chargers, are becoming commonplace. With a multitude of charging uses, powerbanks can keep mobile phones, tablets and more powered up and working at full capacity. Power banks are charged up using a USB charger or thunderbolt dock when power is available, and then used to charge your battery powered devices.

Power banks come in a variety of shapes and sizes to suit your requirements, including solar powered chargers for the eco-minded and QI wireless chargers ideal for smartphones. Solar powered chargers have photovoltaic panels, and are really only able to trickle-charge the internal battery when placed in sunlight because the solar cells are relatively small, but nevertheless this can be a very useful function. The solar charging is a good back-up, especially if you are travelling away from mains power.

Power banks are usually powered by Lithium Polymer or Lithium Ion batteries.

Lithium-Ion batteries are more packed with power and less costly to produce; however, they can age which is an issue.

Lithium-Polymer batteries are more expensive, but are a good choice as they don’t deteriorate with age.

It’s looking increasingly likely that soon we’ll all need our own power bank, so here’s our take on the best-selling ones.

The flashlight is an awesome inclusion and it comes in a range of colors. Even charging four phones at once didn’t stop its battery lasting nearly a week.

This means it’s great for camping trips or long-distance traveling, especially with the compass, emergency whistle and hanging hook. It’s also water and dustproof and, being incredibly robust, designed to survive being dropped.

What Needs Improving
