  • The Auskang 5,000 mAh backup charger available on Amazon for $21.
  • It’s small and thin but sturdy and delivers everything it promises.
  • I wish it could be recharged using the built-in USB-C port.

I have a thing for large power banks: there’s something about larger devices that makes you feel secure with all the power they can hold. But I’m also acutely aware that the bigger the power bank, the easier it is to get left behind, depriving my devices of those sweet electrons.

The first thing that absolutely impresses about this power bank is how thin it is. It’s really thin, much thinner than my iPhone and about the thickness of a few credit cards or a few coins.

When I first saw it, I thought it might be plastic and was worried that the battery might bend and catch fire in my pocket. Luckily, everything is encased in a stainless steel shell that has so far resisted everything I’ve thrown at it.

Sure, I’m sure I could bend it in half if I tried, but the same thing happens with my phone or tablet. What’s important is that it’s powerful enough to handle everyday life.

The power bank has all the basics you’d expect — there’s a power button, four LEDs that show the current charge level, and a USB-C port that can both charge the device and recharge the power bank itself.

It also has a built-in USB-C connector on a short pigtail cable for charging any device with a USB-C port. This awesome twist adds versatility, meaning you don’t need to carry extra cables or rely on wireless charging. Prefer Lightning connector instead of USB-C? Nothing! Only one version is available with just that.

Two outputs allow the power bank to charge two devices at the same time or to be charged while charging another device. This makes it extremely handy for those times when you’re on the go when you need reliable power without the bulk.

And perhaps most importantly, the success of this power bank has freed me from the need to always carry the biggest charger I can find. It offers 5,000mAh capacity, which is not one big amount, but it is enough to charge a modern smartphone once. If you need more than that, you’ll need a larger bag to hold a larger power bank or AC power source.

ZDNET Buying Tips

The Auskang 5,000mAh power bank Perfect for use on the go with your smartphone. It’s small, light and packs a punch. The only criticism I have is that it can’t be charged using the built-in USB-C cable; you’ll need a separate cable for that. Even though the power bank includes a cable, it’s still another item to carry, which somewhat defeats the purpose of taking the light on the go. Think of this power bank as a one-time use case.

Overall, for around $20, the Auskang does a lot for you. If you’re looking for something small, thin, and sturdy enough to carry in a pocket or bag, it’s a great choice.
