Your miniSpinner Classic is a 12 volt device, and many owners run them from rechargeable batteries.  It's a great convenience.  Because a miniSpinner only draws an average of 0.5 to 1.0 amp (about 1.5 amps at maximum load), a relatively small battery can easily run it all day long.  A miniSpinner requires the following in a battery:

  • 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 hour of run time for each 1,000 mAh of capacity)

For your miniSpinner Pro is also a 12 volt device, but the requirements are slightly different;

  • 12 volt output; no more, no less.
  • Ability to deliver up to 3.5 amps of current at 12 volts.
  • Capacity of at least 20,000 mAh (milliamp-hours), or 20 amp-hours. This will easily power a miniSpinner Pro for a long day of spinning. A higher capacity will give more spinning time.

HansenCrafts does not sell batteries.  We have not tested all of these, but the suggestions are based upon the published specifications which are, hopefully, correct.

The batteries listed below are ads, we get a commission on orders placed through the links.

The batteries below should work with both the miniSpinner Pro and the miniSpinner Classic:


This Halo has been recommended by some of our customers.  It is actually an inverter, therefore probably isn't as efficient as the batteries, and weighs 3#.  But it is very simple to use and will work with either the miniSpinner® Pro or the Classic.



The batteries below should work with the Classic miniSpinner only:



And, if you want to play with solar, here's something for you!  I don't recommend it 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 listed above. 

If you have one of the batteries that turns itself off when not in use, try one of these lights! We love them!
