Dubleup Credit Card Power Bank

There’s a saying in photography that the best camera is the one that you have with you, and it’s a similar story when it comes to power packs for smartphones and tablets. The best battery pack is the one you have with you, and to make sure that you do have it with you, here’s the Dubleup Credit Card Power Bank, launching today on Kickstarter.

The Dubleup Credit Card Power Bank can be preordered on Kickstarter with a 15% discount for early birds. Coming in three different colours (black, silver, gold) and two connector types (Apple Lightning and micro USB) there should be a match for both colour preference and device type, though a USB C connector would’ve been cool. I’ve had the power bank for a fortnight and it seems well-enough made with no obvious problems – everything closes up, nothing catches, there are no rough edges. I think the top surface is metal and the back is a high density plastic but it’s hard to tell.

Physically the pack is 86 x 54 x 5.5 mm with curved edges and the connector is built-in, popping out when needed. On the back, there’s a power button and three LEDs showing the charge level in thirds. The height and width dimensions are genuinely credit card sized but the depth means it’s a little fat. To be fair, it was the thinnest one that I could quickly find on the internet from a vendor that I’d trust. The thinness comes at the price of capacity – it’s only 1,280 mAh which would about charge an average smartphone from 20% to full. Obviously it depends on the size of the smartphone’s battery! The charging current is 1A (not 2A) and in the box there’s a short USB to microUSB connector for charging the Power Bank.

I’ve done a quick unboxing video for the Dubleup Power Bank. I say quick but it’s five minutes but should give you a real idea of the size of the battery pack.

Overall, the Dubleup is a small solution to the everyday problem of not quite having enough power to get through the day. It is relatively expensive at AU$79 inc shipping, (US$60/GB£48), for the capacity but if the size means it’ll stay in your purse, wallet or bag when other battery packs get left at home, it’s probably worth it. YMMV. Delivery is expected in June and there are a few early bird discounts (AU$60) if you get in quick.

Thanks to Dubleup for providing the Credit Card Power Bank for review.
