The Powkiddy RGB30 is a distinctive budget handheld built around a 4 inch square screen at a true 1:1 ratio. That screen makes Game Boy, vertical shooters, and arcade boards look incredible. It runs everything through PS1 with ease. A handful of cheap accessories keep it protected and let it reach a TV. For the full review, read our Powkiddy RGB30 review.

MicroSD Card: The One That Matters Most

The RGB30 boots and plays from a microSD card, and a bundled or no name card is the top cause of corrupted saves. Replace it with a name brand card from Samsung or SanDisk. A 128GB or 256GB Samsung EVO Select holds a huge library of 8-bit, 16-bit, and PS1 games and loads quickly. See our best microSD cards guide.

Best Case for the Powkiddy RGB30

The RGB30 has a body shape no other handheld shares. The square 1:1 screen forces a tall, chunky chassis that is wider and blockier than a normal vertical handheld, and that shape is the whole challenge when buying a case. The device is chunky front to back, so depth matters as much as width: a flat case meant for a thin handheld will struggle to zip shut. A device-cut case for the RGB30 is the best fit and the safest protection for the square screen. If one is out of stock, a padded boxy pouch with enough internal depth and a reinforced lid is the reliable fallback. A slim vertical case will not close around the chunky body.

Best Screen Protector for the Powkiddy RGB30

The 4 inch square screen at a true 1:1 ratio is the whole reason this device exists, so protect it, and that square shape is the catch when buying a protector. Most protectors are cut for rectangular screens, so you specifically need one cut for the RGB30's square 720x720 panel; a protector sized for any normal handheld will not match. The screen is not a touchscreen, so this is about scratch resistance only. A tempered glass two pack is the pick, since the square cut is harder to replace later. Clean the panel, line the glass up evenly on all four sides, and take your time squaring it up, because even alignment matters more than usual on a square screen.

TV Output

The RGB30 has a Mini HDMI port for TV output. You need a Mini HDMI to HDMI cable for it, not a USB-C adapter. The square screen content will sit in the middle of a widescreen TV with bars on the sides, which is normal for a 1:1 panel. Pair it with a Bluetooth controller for couch play.

Charging on the Go

The RK3566 is a low power chip and the 4,100mAh battery already lasts around 8 hours, so a compact 10,000mAh USB-C power bank is all you need. It adds several full charges and fits in a pocket. See our best power banks guide.

What You Do Not Need

AR glasses or a portable monitor. The RGB30 outputs video through Mini HDMI, not USB-C DisplayPort, so the one cable glasses and monitor setups do not apply.
A cooling fan. The RK3566 runs cool and does not throttle.
A grip. The chunky body already gives your hands room. Clip on grips add little here.
