Battery-powered keyboards (28)
Battery power is the spec that decides whether a keyboard actually leaves the house. It is what makes street performance, travel practice, garden sessions and lessons without a mains socket possible - and on many models it changes the recommendation on the spot. These are all 28 models in the database that can run away from mains, with what the manufacturer promises.
What to weigh before choosing battery power
AA cells vs internal battery. Most battery-capable pianos take 6-8 AA batteries - replaceable anywhere, expensive over a year of daily play; a few models have built-in lithium packs you recharge over USB. The table below shows the manufacturer's own figure for each model.
Speakers are the battery's biggest enemy. Playing through headphones multiplies the claimed hours; playing out loud at volume burns through cells fastest. Manufacturers usually quote both figures - where they do, we list what the source states.
The keyboard on your lap. Battery keys are usually synth or semi-weighted actions (the mechanism weighs least), and the models that combine battery with Bluetooth - 4 here - are the ones that double as wireless controllers for a phone. If you need hammer-weighted keys and battery in one instrument, the list is short: check the action column on the model pages.

Frequently asked questions
Do digital pianos with weighted keys run on batteries?
A few do - Casio's CDP-S line and some 88-key portables take AA cells with hammer actions. Most battery-capable instruments are lighter, with synth or semi-weighted keybeds.
How long do batteries actually last?
The table lists the manufacturer's own figure, usually 4-13 hours for AA sets, heavily dependent on speaker volume. Through headphones you approach the upper bound; playing loud out of the built-in speakers can halve it.
Rechargeable AAs - yes or no?
Yes for daily home use: standard NiMH cells work in every AA-powered model here and pay for themselves within months. Keep alkalines for the cold and the road, since NiMH self-discharges.
Battery and Bluetooth together?
That combination makes a completely wireless setup - keyboard to phone, sound to speaker. 4 models in this list offer both; the rest pair battery power with cables only.
