If your device regularly runs out of juice while you’re out and about, then consider buying a portable power bank - ideal for keeping your battery at a comforting 100% all day long.

Whether we like it or not, we’re all increasingly dependent on our phones and devices for everyday life and, the more we use them, the quicker they run out of battery.

What’s more, with many of us now working from home, we’re no longer sitting at a desk next to a landline, and our phones have become essential pieces of work kit. Throw in a bit of social media, some online shopping and a quick game on your loo break and, before you know it, your battery situation can look perilous.

How do I choose a portable charger?

If you’re in the market for a portable charger then the main features to consider are the power capacity of the device, plus its size and weight.

The capacity of power banks is measured in mAh (which means milliampere hour). A higher mAh number means that the power bank can store more energy, so it has a higher capacity. For example, a power bank with a capacity of 1,800 mAh could deliver a current of 1,800 mA for one hour. If you plan to use your power bank on long trips away from mains electricity then consider getting the highest capacity you can.

The higher the capacity of your portable charger, the heavier and larger it will be, so make sure to factor in space in a bag when you’re on the move. We’ve included the dimensions and weight in the information about our recommended power banks to help you out.

How long do portable chargers last?

As mentioned above, the capacity of your power bank will determine how long it will be able to keep charging devices for. The greater the capacity, the longer your charger will keep going.

There’s no specific answer because each device which is plugged into a power bank has its own requirements. But, in general, a power bank with a capacity of 10,000 mAh will be able to charge an iPhone up to three times, and a power bank with a capacity of 30,000 mAh may be able to charge an iPhone up to 10 times.

What is the best portable charger to buy?

The best portable charger you can buy is the Anker 26800 PowerCore Portable Charger, a great quality power bank with a large capacity that comes recommended by over 20,000 happy customers.

How we chose our recommendations

Because we know that there’s nothing like a real recommendation from a real parent, we first headed to the Mumsnet forums to find out which power banks discerning Mumsnet users had bought for their homes.
