How to choose the best energy bank for you

You may assume all power banks are much the exact same thing, but you’d be incorrect. You can acquire compact power banks which will charge your phone once, marginally larger portable chargers that might offer a couple of charges, or high-capacity banks that may charge your phone in excess of 10 times.

Working out the number of times each power lender will charge your phone depends on over the mAh rating on the packaging. No power bank is 100 percent energy-efficient, with every mobile charger reducing electricity through voltage conversion and heat generated.

The industry standard for energy efficiency is between 60- and 70 per cent, but some of the best can provide 90 percent efficacy.

We’re seeing a growing number of power banks together with assistance for Quick Charge 4.0 and USB-C, and in some instances these are supported on the input in addition to the outputsignal, making them as fast to refill as they are supposed to charge your phone. Electricity banks can provide these in place of or alongside full size USB, Micro-USB and quad vents.

We’re starting to find power banks which feature an AC/DC socket (a plug socket for non-USB apparatus). Unfortunately many provide just a US two-pin plug, so you may have to carry an adaptor.

Another kind of electricity bank assembles in solar panels. You might think residing in the UK our grey climate would rule out the use of such a device, but even in cloudy conditions these devices can draw a solar power.

Layout is important when it comes to deciding on a power lender, and a few batteries are more compact than many others in the exact same capacity. You can also purchase those protected by the elements, but make sure you check if they’re waterproof or just rainproof.

Nearly all electricity banks utilize LEDs to demonstrate just how much power remains in the device. This can be fine for smaller-capacity devices, but when each LED represents several charges on your telephone it can be tricky to see where you’re. We favour banks with built in LCDs.

Advanced features

Pass through charging is a good feature to have – the capability to control a connected smartphone in the same time as the apparatus itself.

Auto-on and auto-off is another sought after attribute, though sometimes a bank can support this and your phone won’t. It means that you can plug in a device and the electricity bank will begin charging with no pressing any buttons. When charging is complete it will place itself in standby mode to conserve energy.

Some power banks also include an LED flashlight, triggered by double-pressing the power button.

Get the fastest charging speeds

The input rating is crucial when it comes to recharging the lender – the greater is this figure the more quickly it can cost. You will see a figure at Amps, and you multiply this number by the voltage (5V for USB) to discover the rating in Watts.

Do not expect to get a USB mains charger at the box – you can utilize that which was supplied with your tablet or phone. Be aware that a power bank using a 2A (10W) enter will not recharge its own battery any faster than one with a 1A (5W) input signal when combined with an underspecified USB charger.

The reverse is also true when it comes to charging your devices – a phone that supports just a 1A (5W) enter will not charge quicker in the 2A (10W) output.

The output rating describes how quickly a power bank will control your apparatus. Generally you will find 1A (5W), 2A (10W) or 2.5A (12.5W) outputs.

It’s possible to use any output to charge any USB device – it will draw just the electricity it needs. However, you might find some tablets will refuse to charge from lower-specified outputs.

Increasingly power banks comprise clever technology named PowerIQ or similar. This enables the bank to recognise the type of device you have connected and provide the optimum amount of power.

If a power lender has a lot of outputs the highest total output capacity is key, because it might not be able to concurrently encourage each at full power.
