The Anker 767 24,000mAh power bank sets a gold standard for charging tech on the move - and now it’s cheaper than ever

As smartphones become more and more powerful, their batteries struggle to keep up the pace.

Especially as our phones and tablets get older, we're finding the need for a mid-afternoon top-up increasingly necessary - and that's fine if you're by a power point, but if you're travelling or commuting, you'll need a power bank.

While it's possible to buy a half-decent power bank for around £20, if you need it to perform well, you'll need a decent one.

For example, modern power banks can now charge laptops. It's possible to buy one with a big enough output to keep a MacBook going for a while, at the same time as topping up your telephone.

This kind of output comes at a price, and it requires a huge battery. That's one of the things offered by Anker's popular 737 power bank.

It is capable of pumping out a huge 140 watts from one of its USB-C sockets - enough to keep a MacBook Pro 16" happy.

And, while you're doing that, you can be charging a smartphone on its other USB-C sockets, and a smartwatch on its USB-A socket.

Its output is relayed to you through a colour display, which also gives a clear indication of how much charge you have remaining in the power bank itself.

And, when it comes to charging it back up, its 24,000mAh battery will drink in up to 140 watts of power - enough to take it back to 100% in just 52 minutes.

It is, then, one of the best power banks on the market - but it does come at a price. Normally, it costs £139.99 - but you can get a £60 discount on the Anker website right now, with an automatically applied code.

Anker hasn't said how long the discount code will be available for, so if you need a reliable, powerful power bank, jump on this offer while you can.
