Lightweight, affordable, rechargeable teaching electric piano keyboard, connect to USB-USB C port

NuJuly 28, 2021

The media could not be loaded. My husband bought me a piano app that requires connection between the electric piano keyboard and the laptop. We actually own 2 older, pass-me-down electric piano keyboards and an upright piano, and for a long time could not figure out the connection issue, so the piano app was not in full use since we would skip the exercise sections that require a connected piano. This is because the app is able to detect the keys pressed on the piano upon connection to identify errors, and therefore would make testing our knowledge of the note learning better. So for a while, I searched for a connection wire for the older electric piano keyboards, but learned that the older versions do not support this type of connection. I found this piano keyboard, the only one within our price range that is also rechargeable, which is an awesome feature that is not found within other comparable keyboards. With that said, upon turning on, the keyboard would have a red light indicating that it's still charging, whereas it will turn off when fully charged. Coming from using 6-8 expensive D batteries for our older electric piano keyboards to become portable, I so appreciate this novel feature of having a rechargeable piano keyboard! I had only charged it once overnight since receiving this about a month ago, with on and off usage for my app lessons. The manual does explain that it can be charged every 2 months if not in use. It takes about 4 hours to fully charge, and can play up to 6-8 hours of continuous play after a full charge. What's more, the charging cable is a regular USB to type C USB cable, which I already own many of for my Android phone. This means we're no longer afraid to misplace or lose the charging cables, not to mention again saving so much money on those expensive replacement cables that are only specific to the piano. From getting frustrated whenever we lose the power cable for the order electric piano keyboards to now having such an accessible and rechargeable cable, I'm really on cloud nine with this piano! Another lucky find is that this piano comes with a microphone. When purchasing, I really didn't expect this surprise find from reading the product descriptions, as I don't remember having read anywhere that a microphone comes with it. It's located snugly and conveniently at the bottom of the keyboard in case you missed it. I love that this is genuinely a teaching piano keyboard. There is a function called teach: OKON (one key for one note)/Guide/Follow with a metronome and a beat count that you can set up to 1, 2, 3, and 4 counts, though I can't figure out yet the difference between the metronome and beat functions. Nevertheless, this is also a cool and unique feature that I have not seen before. I'm also learning via a piano app at this time, so I'm not using this teach function. But when trying it in teach mode, the correct key notes will appear on the LED screen. To be honest, at my stage of learning, I don't really understand what the notes say anyway. I'll probably revisit this teach function once I'm more familiar with reading the notes. It has 37 keys which is suitable for beginner or even intermediate piano lessons. Once we get to more advanced lessons, we're planning to upgrade to the 61 keys by this brand. But honestly, except for being 37 keys, it has so much more functions than I know what to do with, and with the teaching function available, I know it will take me a very very long time of practice on this keyboard before even thinking of upgrading to 61 keys. With that said, I'm so impressed with this small but mighty teaching electric piano keyboard, but it does take some time to familiar myself and make use of all the functions. I'm still learning new functions to date. Some tips: It's super lightweight compared to my older keyboards. The microphone goes into the MIC port. Tuck it back into the slot at the bottom of the keyboard for storage. Headsets or earphones (not included) can go into the PHONES port. It comes with an extra audio cord which can go into the AUX IN port for additional audio connection. There are no specific volume + / volume - buttons. To change the volume, click on VOLUME and then choose CHOICE - or +. I had to search the manual to learn this, after my husband complained why the piano is so loud, and I frantically could not find the typical volume + / volume - buttons. I think this is a very clever way to condense the buttons because the CHOICE - or + buttons can also be used for other functions such as TONE SWITCH, TEMPO, TRANSPOSE (to adjust the Major), and RHYTHM SWITCH functions. There are 50 demos, 200 tones and 200 rhythms, and I can see how fitting all these in a small, lightweight keyboard would not have been possible had it not been for the alternative. Apparently, when choosing from 200 rhythms, I can fill in a percussion of my choice, then record, and play back as background music. This is way too advanced for me at this time, but so cool! In place of the pedal on the string piano, I can use the SUSTAIN mode to extend to key sound, VIBRATION mode to add vibrating key sound, or ECHO mode to add the echo key sound. I'm not able to multitask that much yet, so I can't quite figure out how to efficiently do this. To sum it up, I cannot believe this rechargeable teaching electric piano keyboard was only around $50 after tax, whereas I remember paying 3-4 times as much for my older electric pianos. For those who have bought or signed up for an online or in-app piano lessons, I highly recommend buying this gem for your study. Trust me, the piano lessons, especially the practice games, are so much more enjoyable with it. Read more

Very good keyboard for kids and beginners

Linda CApril 15, 2025

My husband is a musician so he bought a bunch of musical instruments for our 2 babies to “rain them young”. He picked this keyboard because it has rechargeable battery, doesn’t look like a toy, has different sounds and beats and songs, and even a microphone. The keyboard is pretty well built, light and portable, the sound quality is a lot better than most of those kiddy keyboards. Even the mic works ok and our son loves singing (babbling?) into it. We haven’t run out of battery yet and the battery life is advertised to last 6-8 hours, and it turns off automatically after awhile. This is not a professional keyboard - the sounds don’t sound very realistic, the keys are not velocity-based and don’t feel like a real piano, but considering its price point, the keyboard beats all expectations. We did receive a unit that has a broken key, but a replacement quickly arrived which works perfectly. Read more

Flimsy, failed early on.

JoeyOctober 16, 2023

When we received this it had plastic pieces rattling around inside. But it seemed to work so we charged it and gave it to our son to play with. Turns out the battery lasted less than an hour. This was frustrating, but we thought he could play with it while plugged in. Nope; this unit doesn't work that way. It plays on battery or nothing. Bought a 2A USB power supply, didn't make any difference. Meanwhile, the battery life was going down fast, only running the unit for a few minutes at a time. I thought maybe the bad battery was taking all the current from the power supply, so I opened the unit and removed the battery. When I got the unit open I found three of the plastic pylons meant to receive the screws to hold the case together had broken off, and there was a mystery piece of white plastic about 2mm square, also. Put the unit back together, tried to run it, nothing. But in reassembling the case I managed to break another one of the pylons. The case is made out of very flexible, thin and easily breakable plastic. Even if this had worked, I doubt it would've lasted more than a few weeks of actual playtime. To add insult to injury, while I was attempting to repair it I caught my finger under the edge of one of the keys, which bent upwards. Evidently there is no form of key retention in the unit at all. The whole thing is built on a shoestring budget. Into the trash it went. Wasn't worth a tenth what we paid for it. When I heard parts rattling around and felt how lightweight it was I should've sent it back immediately. How people can pay fifty dollars a pop for these and still file 4 and 5 star reviews is inexplicable. I guess we just don't expect much out of Amazon products these days. Read more

Nice little starter keyboard

Zackary GonczSeptember 30, 2025

My niece liked it. Smaller, but nice little starter set for a young person interested in music, a beginner. A lot of options and programmed effects and things. The instructions could be better though. I messed around with it for enough time that I felt like I should have been able to figure out how it worked. But time would fix that obviously. Still, kids don't have good attention spans. Sounded good, louder than you might expect. Read more
