Review: PowKiddy V90

Last updated: 17FEB2021

I wasn’t expecting much from this device, but I underestimated it. After a disappointing experience with the TrimUI Model S, this little clamshell device was everything I was hoping for in a budget handheld.

Buy one here!


One of my favorite aspects of this device is the fact that it just uses a Nokia phone battery, and it’s easy to access and swap. If you’d like to buy a replacement (or upgraded) battery for the device, here is the recommended model.

The custom firmware for this device makes a huge improvement to your experience. Install the MiyooCFW 1.3.3 firmware here. Once you have installed the new firmware, there are a few recommended tweaks to increase performance:

Update certain emulators:

  • Download the latest version of snes9x4d (SNES) and place it in the emus/snes9x4d/ folder (replace the one that’s already there).
  • Download the latest (“PocketGo”) version of Gambatte, (GB/GBC) and place it in the emus/gambatte folder. Make sure it is just named “GAMBATTE”, and replace the one that’s already there.
  • Download the latest “improved” beta version of fceux (NES) and place it in the emus/fceux. Make sure it’s named just “fceux” and replace the one that’s already in there.
  • Download and unzip the latest version of pcsx (PS1) and place it in the emus/pcsx_rearmed/ folder (replace the one that’s already there).

Add BIOS files:

  • If you want boot logos for Game Boy, Game Boy Color, and Game Boy Advance, add the bios files for each emulator. You’ll definitely want to do this for GBA anyway, since it will improve compatibility and performance. Once you have added these files, you will need to turn on the boot logo (“boot to bios”) option in the Gambatte and GPSP emulator settings.
    • gb_bios.bin goes in the .gambatte/bios folder
    • gbc_bios.bin goes in the .gambatte/bios folder
    • gba_bios.bin goes in the emus/gpsp_rumble folder
  • The PCSX ReArmed emulator also needs bios, which is the SCPH1001.BIN file. Place it in the emus/pcsx_rearmed/bios folder. For best results use the PSP’s PSX BIOS (often described as “PSXONPSP660.BIN”), because it has the fastest performance of all tested BIOS files. Just be sure to rename it to SCPH1001.BIN when adding it to the folder.


  • Using custom firmware, tap the function button to place the device in suspend mode
  • Using custom firmware, press R1 + START (or hold START for a few seconds) to bring up the safe shutdown menu

  1. My internet buddy wanted one of these, and I told him about the screen tearing and low performance. ZeePeezy had already made a couple of videos about it so I knew to steer clear since I already had a LDK vertical. “But it’s SO Kawaii!!!” Was the immediate response , and yeah, that’s why you get one. You want the GBA sp without the hefty price? There you go! The colors match your favorite Pokemon? There you go! He loves it, but I’ll stick with the LDK. It’s around the same price and Gameblabla has done some amazing things with it (like a Super Mario 64 port.) Since they use the same battery here’s a tip: the Taeozi BL-5C 1600mAh battery is one of the best I’ve tried. There’s one that promises 2450mAh, but it’s a scam. Peel off the pretty gold label, and you’ll find that it’s a normal Nokia battery. After installing the Miyoo custom firmware you’re definitely going to want a new battery and the Taeozi batteries come in a two-pack so if one croaks on you you’ve got a backup. Hope this helps!
