A new accessory that launched earlier today on the crowdsourcing platform Indiegogo attempts to solve an important concern with mobile devices—battery life—with an interesting twist.

Dubbed the PowerMe, this tiny multi-purpose dongle turns almost any mobile device outfitted with a microUSB port into a mobile battery pack for your other gadgets, including Lightning-enabled iPhones, iPads and iPods.

In addition, the PowerMe lets you share photos, music and other documents between devices and it’s small enough to easily snap onto your keyring.

Three devices in one

Created by three young students from Italy—among them Francesco Crema and Ludovico Cianchetta, the brains behind the Adappt, an affordable Apple Watch band adapter—the PowerMe can charge any microUSB or Lightning device by taking power from most smartphones and tablets.

“Mobile devices are all around us, and every device is a potential power source,” reads the site. ”With PowerMe, you can take energy from your friend’s phone, or share yours if someone needs it.”

The accessory includes a Lightning adapter allowing you to charge your iPhone, iPod touch or iPad from another device. Another cool thing about the PowerMe is that it doubles as a classic USB-A charging cable via another included adapter.

It allows the PowerMe to be easily plugged into your computer, or USB wall charger, and charge your microUSB or Lightning device.

As mentioned, you can use the PowerMe for syncing and sharing files between devices because it supports USB standards for data transfers. For instance, you can use the gadget to transfer videos and photos from a GoPro camera to your iPhone.

The PowerMe is compatible with USB OTG (On-The-Go) standard which permits USB devices like smartphones to act as a host. This lets other USB devices, such as USB flash drives, digital cameras, mice or keyboards, to be attached to them.

They’re aiming to collect $10,000 to take the PowerMe off the ground. Multiple tiers are available to early-bird backers, starting at $9 for the PowerMe itself, a 20 percent discount on the full price wit such perks as free international shipping and a free USB adapter.

The accessory will be available in white, gray, green, blue red and orange. Full production starts in December and first shipments should be expected in January 2016. You can back the campaign and secure your sample of PowerMe over at Indiegogo.

    So, would this kind of be a solution for transferring 4K video from the iPhone 6s to the iPad pro?

    • Hi

      hmmm, if it was USB 3.0 it would be good

    • No sorry, one of the two devices needs to be microUSB. You can transfer videos to any Android device, but two Apple devices won’t work.

      • iBanks

        Got you.

      • :D

        Will two Apple devices work if I get the lightning adapter?

  • Hi

    Wow, i have pre orderd 2 with lightning port adapters

  • Merman123

    Is that safe?

    • Yes it is! It follows USB standards. It’s just the same as connecting to your computer

    I really believe in this project. I always wanted to design something like this but I don’t have the skills to do it. Nice work PowerMe team!

    • Really thanks! We love your support!

  • Bronson

    At what rate would an ipad air charge an iphone 6? How fast?

    • Sorry but the device giving charge cannot be an Apple device, due to Apple limits

  • Jaskaran Chadha

    will it work if i order an extra lightning adapter along? that way it can connect to apple products on both side.Will file transfers be possible with that?

    • No sorry, the problem is that you can’t take energy from an Apple device

    This is cool! I always wanted one but didn’t think it’ll be made so I bought a power bank instead lol

    Serious security question…. if I plug my phone (iPhone, but it could be an Android) into another person’s phone…. could I just copy their photos off without any interaction on the source phone? That would be a serious security concern… and remind me of a lot of recent “spy” movies lol

    • iPhones do ask for confirmation before accessing. Not sure about Android, but, as far as I know, latest versions do this as well.
      Once the access has been granted, yes, you can copy everything you want. But, how could something like that happen?
