    Stay powered up

    From online shopping on your lunch break, to making plans over the group chat, to sharing snaps of your dinner, you can use up a lot of juice in a day. But with the Griffin Power Bank's 5000mAh battery, you can get up to two full charges of your smartphone. So you can carry on doing the stuff you love, for longer. Like to keep tabs on your notifications and step count through a smartwatch? Make sure you pack your power bank – it can charge your smartwatch over 15 times.

    Keep it simple with wireless charging

    Feel like you spend half your day untangling your cables? The Griffin Power Bank lets you charge compatible phones wirelessly, so it's easier than ever to power up when you're on the go. And if you've got a phone without wireless charging, just plug your cable into the USB port. It's that simple.

    Don’t get caught out

    If your phone's on low battery, the last thing you need is a power bank that's run out of charge. That's why the Griffin Power Bank has LED indicators to let you know how much battery it has left. So you can go about your day knowing for sure that you've got a back-up power source. And if your phone and power bank run out of charge at the same time, it's no biggie. It has pass-through charging, which means you can charge both of them at the same time.
