Your miniSpinner is a 12 volt device, and many owners run them from rechargeable batteries. Because a miniSpinner only draws an average of around 0.5 amp, a relatively small battery can easily run it all day long. A miniSpinner requires the following:
- 12 volt output (CAUTION: if your battery has multiple outputs, be certain to set it to 12 volts!)
- Power connector is 5.5mm x 2.1mm, center positive (most common configuration)
- Recommended capacity 10,000 - 20,000 mAh (figure about 1-2 hours of run time for each 1,000 mAh of capacity)
The latest (and simplest) solution is to use a modern USB-C battery bank (or AC charger) and an inexpensive adapter that we sell. We use these to demonstrate miniSpinners at events.
- NOTE: A USB-A (the large rectangular plug) source will not supply 12 volts.
The USB-C power source must supply 12 volts, be sure to check! You can determine this from the specifications on the power source:

We like this Anker battery:
The batteries below can be configured to output 12 volts but they're an older solution, more expensive, and often more complicated:
*TalentCell Rechargeable 12V 38400mAh
*Krisdonia Power Bank 50000 mAh
The following batteries have inverters that produce 110 volts AC power, therefore they are not as efficient as the batteries above. But they are very simple to use and will work with either the miniSpinner® Pro or the Classic.
*Talentcell Rechargeable 12V 11000mAh
*HALO Bolt Wireless Power Bank
And, if you want to play with solar, here's something for you! I don't recommend solar for powering your miniSpinner directly as the output voltage will vary too much to work well, and in intense sunlight the voltage will be too high.
It would, however, be just fine for charging one of the batteries.
*ZeroKor Portable Power Bank with Solar Panel bundle
If you have one of the batteries that turns itself off when not in use, try one of these lights! We love them!
