Nokia has announced a new product that’s supposed to be the “first mobile phone with a mobile phone charger.”

The Nokia Mobile Phone Cage, which is available as an accessory for your Nokia Lumia 925 or Lumia 1020 phone, uses an external battery that charges a Nokia handset when you plug it in and discharges it when you put it back in.

It’s not clear how long it takes to charge and discharge the battery inside the phone, but it looks like Nokia’s marketing team has a lot of ideas for what the cage might be used for.

In an Instagram post, Nokia says the Nokia Mobile Phones Cage has a charging capacity of up to 30 hours and a power usage of “50W.”

The company says it also supports charging via Bluetooth 4.0 and NFC, and can be charged in minutes.

Nokia says it has tested the Nokia Cage in Australia, New Zealand, Japan, the United Kingdom, and the United States.

The Nokia Cage is currently only available in white, silver, and gold color options, but Nokia says that it will be releasing more colors and variants in the future.
