Want to take your Raspberry Pi projects to the next level? You’ll need a battery solution to take it mobile, but it’s easier than you think. Several mobile power options are available, from dedicated solutions designed for the Pi to custom-built DIY batteries. Get your Raspberry Pi out of the house and involved in some mobile projects, powered with one of these four options. Portable Power Requirements for Raspberry Pi Just like static Raspberry Pi projects, portable uses for the Raspberry Pi need to be powered by a good quality 5V micro USB mains adapter with a 1.2A (1200mA) current (although 1000mA should suffice for most projects on older Pis). However, the USB ports benefit from a supply of 2.5A (2500mA) if you plan to connect devices without a powered hub. Which power supply you need depends on the final application of your Pi.
