Explore beyond the range of power outlets with a DC charger for the Onewheel.  Recharge directly from battery to battery with no conversion to AC, and no need to bring the Onewheel charger.  The kit includes a protective box sized for a standard 36v 4.4ah hoverboard battery, which can provide a single full charge for the Onewheel.  A boost converter slides onto the top of the case and converts the output of the battery to the 58.4v that the Onewheel charger normally provides.  

The boost converter can handle up to 30A on input, and 20A output.  The high limit on input current means it can boost batteries as low as 12v, so long as those batteries can output 15-20A.  It has a vey large heat sink, and is capable of fast charging a Onewheel at 5A without the need for a noisy fan.  It can continue to perform while zipped up inside a pack, making it ideal for charging while riding.

The controller comes set to a default output of 58.4V and 5A for charging the Onewheel+.  The 5A output provides a fast standard charge of around 25 minutes, and a fast enough charge while riding to keep up with a relaxed pace.

The settings can be changed to 63v 3.2A for charging a Onewheel+XR.

The battery box has rails on both the edge and the face, so there are two options for mounting the charge controller.

The displays on the controller show the source battery status and the output voltage.  The display for the battery can be toggled between voltage and battery capacity.  The capacity display is based on a 10S Li-ion battery, which is the configuration of a standard hoverboard battery.

The battery is not included in the kit, but hoverboard batteries are easy to find on Ebay, ranging from $35 to $60.  Search for "36v 4.4AH battery".  Batteries made from Samsung or LG cells will be the best quality, though a little more expensive on average.  These come in a standard configuration which will fit in the case.  The actual capacity might vary a little, so it is wise to do a test charge before going out into the field.

Extra cases are available for additional batteries, and the charger can be ordered with a double battery case for holding two batteries connected together.  When charging while riding (CnR) it's best to use two batteries wired together with a splitter.  In addition to the extra range, they share the load and do not heat up as much as a single battery.  The double battery setup runs cool enough to stay zipped up in a backpack, but a single battery should have ventilation available, or be removed from the pack while charging.

The charge controller and battery together weigh about 4lbs, and single batteries about 2lbs each making 6lbs for two charges.  By comparison, a Chafon UPS battery backup weighs 7lbs for two charges and still requires the Onewheel charger for 9lbs altogether.  With a single charge per battery, you can choose to pack however much power you think you will need.

The kit includes a charger for the hoverboard battery, and a fireproof lipo charging bag to hold them while recharging.  The Li-on cells that make up a hoverboard battery are safe, and fires are extremely rare.  However it is best to only charge them when you are present, and keep them in a fireproof container.
