I love my Nintendo Switch and when I got it last month among my first purchases was a case. Taking it on the road I was unsurprised to discover it could only go for two or three hours. The second thing I needed was a battery pack. I wanted something that could charge my Switch, my Samsung Galaxy S7 and whichever tablet I had with me. Enter the Aukey USB C Power Bank 30000mAh.

The Power Bank has a fairly conventional design – it’s a small rounded brick. All of the ports – one USB-C, one microUSB and two USB are on one end with the torch. One of the USB Ports is green on one is orange but there’s no marking as to which is the Fast charge port which can sometimes lead to plugging back and forth. It’s switched on and off with the single slightly recessed button on top. The button also glows to show the level of charge – white between 70 and 100%, green 30 – 70% and red between 0 and 30%.

It’s not a light carry at over half a kilo but isn’t over heavy for it’s capacity either. The bank is made of ABS plastic that while not completely smooth isn’t ridged and is not that ergonomic to hold. It is however just about small enough to fit in a pocket which lets you charge on the go.

Lets talk capacity. The Power Bank has 30,000 mAh which is fairly huge. For comparison, the iPhone 7 has a 1960mAh battery, while the iPhone 7 Plus has a 2900mAh one. The Samsung Galaxy S8 has a 3000 mAh and the S8+ has 3500mAh. Moving on to tablets the iPad Air 2 has a 7340mAh battery and the iPad Pro has 10,307mAh. Finally, the Switch has a 4310 mAh battery. There’s always going to be some loss in the system but that works out as maybe 10-12 charges for an iPhone, two and half for an iPad Pro or maybe five for a Nintendo Switch.  This weekend I took the Power Bank with us away and charged three phones an iPad and a mifi from it over three nights and two days and it took the battery down to around 30% charge.

Capacity isn’t the only aspect of a batter that matters – the amperage is almost as important. This makes a difference both in terms of the speed your device can charge and when it’s a high draw item whether it can charge it all. The higher charge port can put out at 6.5V/3A which has been enough to charge every device I’ve found including my Switch, iPad and Dell Venue Pro.

The Ergohacks Verdict

Power banks get bigger. It seems to be a fact of modern tech life that every power bank and battery we see is larger than the last. They also have more specs and standards and can output more and more voltage. The battery that I carried 10 years ago now seems laughably small. These days you want a battery with FastCharge, with a big capacity and one that can output decently high wattages for your more unusual devices. The Power Bank hits everything I want in battery and lets my whole family keep charged on the go. It might be a little too large for some people’s pockets but if you’re willing to deal with the weight then it’s a great gear bag choice and for Nintendo Switch owners a near Essential.

  • Qualcomm QuickCharge 3.0
  • Turbo Recharge. The Power Bank can recharge via its microUSB port, via USB-C or both for much faster charging. Aukey quote about 8 hours to fully recharge from empty using both charging ports and while it’s a difficult test to replicate without the same wall chargers I was able to completely recharge in about 9 hours.
