Microsoft has just made yet another step to replace the Nokia brand with its own by launching its very first portable phone charger that would go on sale across official stores this month.

The so-called Portable Power charger comes with a rechargeable 6000 mAh battery and uses a microUSB port to connect to most smartphones out there and provide some additional power without the need for a wall socket.

The European Union last year decided to make microUSB ports mandatory on all mobile devices, thus calling for a common standard that would help buyers of smartphones and tablets to charge their gadgets without having to carry around more than a charger.

Microsoft's decision to go for microUSB on its portable phone charger makes sense not only following EU's new regulation, but also because all of its phones are using this standard right now, as well as the majority of Android smartphones on the market.

“It keeps a full charge for months”

Microsoft says that its new device comes in very handy for those who travel a lot because it can provide additional battery juice wherever you are.

And if you don't need to use it, you can simply carry it around with you for months without recharging because Microsoft claims that it comes with a standby system that saves battery for more than six months.

“If you’ve got concerns about the need to keep charging the Microsoft Portable Power, forget them. Because of the device’s low standby battery consumption, it keeps a full charge for months. Even after six months, the Microsoft Portable Power will have 80 percent of power,” Microsoft said.

“But if you do want to top up the stored power, you can do so via USB. Alternatively — and here’s a nice idea — you can daisy-chain the Microsoft Portable Power and your Lumia together and charge both at the same time. Priority will go to your Lumia, of course.”

Enough battery life for almost two Lumia 1520 phones

Thanks to its 6000 mAh battery, the Portable Power charger can help you fully recharge two Lumia 1520, which come with 3400 mAh batteries that Microsoft claims are enough for at least 2 days of heavy use.

As far as the Lumia 520 is concerned, which is quite the best-selling Windows Phone on the market, the Portable Power device can really come in handy because it can recharge its battery for almost five full times. The Lumia 520 comes with a 1430 mAh battery.

Microsoft's Portable Power will go on sale in October in the company's official stores and at authorized retailers for $49 (€39). The device will be available in multiple colors namely white, bright green, and bright orange.
