The Raspberry Pi runs on battery!


To make your Raspberry Pi time lapse device more portable you can add a battery pack!
Anker 10000mah Astro 3e on Amazon

Anker Astro 3E 10000mah Battery Set

The Anker Astro 3e Battery pack is available with 10000mah cell and features dual usb output BOTH at 1A – This allows you to charge an average smartphone 5 times from the battery.

Specifications on back of box:

Anker battery specifications

Product is supplied with a short usb cable and various adaptors to allow connection to major products (and Raspberry PI)


The Battery arrived fully charged but charging from empty takes around 20 hours. It features 4 lights that indicate how much charge is left in a minty blue colour. In my early tests I have connected the battery to the Raspberry PI and powered it continuously for 14 hours.

In my test I used a Model B Raspberry PI with Camera and Edimax Wifi Dongle connected using wifi. No keyboard, No Screen. Just used putty to connect to it.

To keep it busy I ran a time lapse screen capture every 15 seconds for over 12 hours.

The battery was still functioning on its last blue segment – but felt happier being able to shut down the PI safely! (didn’t want to corrupt my memory card!)

Overall I would say this is a very good well built product. Highly recommended.

  1. Does the anker continue supplying the Pi if you plug the anker in to charge? In other words, can you use the anker like a UPS for the Pi?

    1. Hi Matthew,
      I have not yet tired but will give it a go in the next couple of days.
      I notice from the specification it can only charge at 1000mah and outputs dual 3100mah. If this is the case & it does charge the PI takes approx 500ma therefore may work without any heavy duty extras… I will let you know (hopefully tomorrow) Cheers,

  2. My Anker Astro3 (now Astro Pro) 10Ah’s charger is a 12V, 1A charger, i.e. 12W.
    Note that the outputs are 5V, 12W/5V=2.4A, minus losses, much more than the ~0.7A@5V Raspberry Pi maximum.
