To keep your phone, tablet or other USB device going all day you need a power bank. They come in all shapes and sizes but the absolute basic function is to recharge your device when it’s needed. If you travel a lot and can’t easily get to a power supply, then a powerbank is a must have piece of kit, giving you peace of mind and keeping you connected at important times. For example at the end of a long day and you need to get home, the last thing you want is to be without your phone because it’s out of charge.
Choosing a power bank
Several factors are important when choosing a power bank. One is portability: some of the power banks we review are small and light enough to slip into a pocket; others you’ll notice their presence even when slung in a bag. Pay particular attention to their weight and avoid bulky designs if this is a device you’ll carry every day, rather than in certain situations only.
Another factor is capacity. It’s important to note that a power bank will not deliver its full advertised capacity to your device – some of this energy is lost through heat generated and voltage conversion. If a power bank manufacturer doesn’t expressly state otherwise, expect to achieve around 70 percent efficiency. A 10000mAh power bank might therefore deliver 7000mAh of power. Some of the best power banks offer around 90 percent efficiency. Check the specification of your phone or tablet’s battery to estimate how many full charges you can expect from this.
Most standard powerbanks rely on being charged from the USB port of a computer or some may charge from the mains. Our powerbanks have this feature but have the extra benefit of using solar power as an additional source of charge.
Our ranges of solar powerbanks
We have several solar powerbanks available so it’s best to search and see what’s available. Alternatively get in touch to ask any question.
Generally we recommend charging the solar powerbank conventionally using USB power connections, but a couple of hours in the sunshine will top-up the charge and may get you out of trouble. See our PowerPlus Zebra as an example of an affordable powerbank.
