Our Verdict
At $280, the DEP-45 costs less than dinner for two at a nice restaurant — and it gives you 88 keys, Bluetooth MIDI, battery power, and 200 sounds. The catch? The keys aren't hammer-action.
Pros
- • Under $300 — one of the cheapest 88-key keyboards on the market
- • Battery powered — play anywhere without a power outlet
- • Only 7.5kg — light enough to carry under one arm
- • Bluetooth MIDI for connecting to piano learning apps like Simply Piano
- • 200 sounds with layer and split modes — generous for the price
- • Built-in lesson function, recording, and 50 preset songs
Cons
- • Semi-weighted action — NOT hammer action. The keys feel like a keyboard, not a piano
- • 3.5mm headphone jack only — you'll need an adapter for standard headphones
- • 10W speakers are thin and quiet — adequate for a bedroom, not much more
- • No headphone optimization — the sound through headphones is flat and unspatialized
- • Build quality reflects the price — the chassis feels plasticky
The DEP-45 is not a piano — it's a keyboard with 88 keys and some piano-like features. And that's fine, because at $280, it removes the financial barrier to starting. The battery power and 7.5kg weight make it genuinely portable in a way that heavier models aren't. The Bluetooth MIDI lets you connect to learning apps. But be honest with yourself: if you get serious about piano, you will outgrow this instrument within months. Think of it as a trial run, not a destination.
Technical Deep Dive
About the Key Action
This is the DEP-45's biggest trade-off. Semi-weighted keys have some resistance but lack the hammer mechanism that simulates real piano weight. They feel more like a synthesizer keyboard than a piano. The keys are responsive enough for casual playing and learning basic melodies, but they won't teach your fingers the proper strength needed for acoustic piano. If developing real piano technique matters to you, save up for a hammer-action model.
Who Is This Piano For?
You're not sure if you'll stick with piano and you don't want to spend $500+ finding out. Maybe you're a college student with a tight budget, or you want something to bring to a friend's house or play in the park. The DEP-45 is the lowest-risk way to start — if you love it, you can upgrade later. If not, you haven't lost much.
