A digital piano is an electronic keyboard that plays piano sounds through built-in speakers or headphones, and in listings the term electric piano means the same kind of instrument. The digital pianos here all have 88 keys and weighted or semi-weighted action, so the choice comes down to tones, connections and what comes in the box.
What a digital piano is
A digital piano is an electronic keyboard built to stand in for an acoustic piano. It has 88 full-size keys, and the keys use weighted or hammer action so they push back like piano keys. The sound comes from built-in speakers, and a headphone jack lets you play without the speakers. It needs power from an adapter or a battery.
What electric piano means in listings
In listings, electric piano is used as another name for a digital piano: the Donner DEP-20 is called a digital piano in its name and an electric piano in its own description. When you shop, read the keys, the action and the connections instead of the label. A listing that names 88 keys, weighted action and USB-MIDI describes a digital piano whatever the title calls it.
Compare the key count and the action
A full piano has 88 keys, and the digital pianos here all have 88 keys. Weighted and hammer action keys push back under your fingers, while the GLARRY uses semi-weighted keys with spring resistance. Check the action in the listing: the Yamaha P71 names weighted action that replicates the acoustic piano experience.
Compare tones, connections and the box
The GLARRY has 380 tones and the Donner DEP-20 has 238, while the Yamaha P71 has 10 voices and the UISCOM has 8 tones, so the range of built-in sounds differs a lot. For connections, the GLARRY has Bluetooth audio and USB-MIDI, and the Donner DEP-20 and the UISCOM have USB-MIDI. The GLARRY comes with a stand, triple pedals and headphones, the Donner DEP-20 comes with a furniture stand and a 3-pedal unit, the Yamaha P71 comes with a sustain pedal and a power supply, and the UISCOM comes with a power adapter.
