The Perks of AC Power with Rubjoy

Rubjoy runs on continuous AC power. There is no internal battery — the machine plugs into a wall outlet and runs for as long as you want without interruption, power fade, or the need to recharge between sessions.

This is a deliberate design choice. Batteries in high-draw motorized devices deplete faster than their rated capacity suggests, degrade over charge cycles, and introduce the possibility of the machine slowing down or stopping mid-use. AC power eliminates all of that. The performance at hour one is identical to the performance at hour three.

Power supply specs

The included power supply accepts 100–240V AC input, which covers the voltage standards used in North America, Europe, the UK, Australia, and most of the world. If you are outside North America, you need a plug adapter to fit your local outlet — the power supply itself handles the voltage conversion automatically.

The power cable is removable and replaceable

The cable that connects the power adapter brick to the wall outlet uses a standard figure-8 connector — the same type used on many laptops and electronics. It detaches from the brick. This means if you are traveling internationally and want to use a local cable rather than carrying a plug adapter, any locally purchased figure-8 power cable will work. It also means the cable is replaceable if it ever gets damaged.

Running Rubjoy without a wall outlet

Rubjoy requires AC power, so a standard USB power bank will not work. For mobile use — travel, outdoor use, or anywhere without a convenient outlet — use a power bank with a built-in AC inverter output. These are widely available and provide a standard AC outlet from a portable battery. Rubjoy's power draw is low, so a mid-size inverter power bank will run it for several hours on a single charge.

*the power cable with the plug attached is REMOVABLE from the power adapter brick. Meaning you can replace it with a local 'figure 8' electronics cable - or use a plug adapter.
