If you’re trying to understand watt hours, voltage and power management, then shopping for portable chargers can become a little bit daunting.

Not only can you charge three gadgets at once – ideal for refuelling your phone, earbuds and Apple Watch simultaneously – there’s enough juice inside to deliver seven charges to an iPhone 8 or bring a more recent iPhone 13 to 50% in around 40 minutes. That’s impressive. At Anker, we care about your safety. Our MultiProtect system combines surge protection, short circuit prevention, and many more advanced safety features to give you peace of mind. Don’t know your USB-A from your USB-C or Micro USB? It doesn’t have to be too confusing. The older USB-A is the connector you’ll have seen often over the past 10 years or so (think little portable USB drives) while the newer USB-C connector is the one that has come with the newest Androids and iPhones (on one end at least, these still charge via Apple’s Lightning port). There’s a good reason the GH Tech Team added this model to our list of the best power banks: it gives you a big capacity without the size (and high price) of the more imposing Anker 737, although if you do fancy it, there's a 36% on that model, too.Comprehensive Safety System: Anker’s exclusive MultiProtect technology combines 10 safety features that work together to provide complete protection for your devices, your chargers, and most importantly, you.

A big power bank with 20,000mAh or more will deliver almost five charges for an iPhone 13 – and we’d recommend this size if you want to charge bigger batteries like those in an iPad or laptop. These are also about as big as you can bring on a flight (more on that below). Power for Three: Charge 3 daily items, such as your phone, earphones, and Apple Watch – all simultaneously from a single device.While you’ll probably have most of the cords that you’d need, we’d expect a power bank to at least come with a recharge cable and maybe some extra useful wires. It’s also a nice extra when it comes with a decent carrying pouch to keep the battery and cables together. What is the largest power bank allowed on a plane?
