A new rugged feature phone designed to double as a portable charger is currently in development at HMD. Leaked by industry insider smashx 60, the Nokia 300 4G Power Bank combines a 3700 mAh battery with 2 SIM card slots and an IP65 durability rating. But the official release date and retail price remain unconfirmed.
The primary draw of this upcoming device is the large battery capacity. At 3700 mAh, it dwarfs standard feature phone batteries and supports 18W fast charging. The leak suggests this capacity delivers up to 44 days of standby time or 26 hours of continuous talk time. It also powers an integrated flashlight that is reportedly 2 times brighter than the one on the iPhone 16 Pro. Owners can run the flashlight for 23 hours or play music for 19 to 26 hours on a single charge.
To function as a portable charger, the phone uses a dedicated button on the side of the frame to trigger 5W reverse charging. The package includes a multi connector cable featuring 2 Type C plugs, 1 Type A plug, and 1 Type B plug. This setup allows users to power up external accessories and smaller gadgets directly from the phone. The physical dimensions of the chassis are 136 by 55 millimeters with a thickness of 14.95 millimeters.
Beyond its battery capabilities, the device remains a basic communication tool. It features a 2.4 inch QVGA display and a basic 0.3 MP camera on the back. It supports storage expansion up to 32 GB using memory cards. Additional hardware details include Bluetooth connectivity, an FM radio, and a standard 3.5 mm audio jack. HMD has not yet announced when this 3 color lineup will hit retail shelves.
