Device Overview: PowKiddy RGB10S

The PowKiddy RGB10S is a pocket-sized horizontal handheld that copies the silhouette of a shrunken Game Boy Advance, right down to the offset thumbstick sitting where the GBA’s d-pad used to be. It arrived in March 2022 as a mid-cycle refresh of the original RGB10, and under the shell it runs the same Rockchip RK3326 that powered a whole generation of sub-$100 emulation handhelds, from the Anbernic RG351 line to the Odroid Go Advance. That immediately tells you what it is and is not: a cheap, capable retro machine for 8-bit through PlayStation, not a device that will ever touch a modern 3D console. What PowKiddy changed for the “S” is mostly cosmetic and tactile: a sharper IPS panel and reworked face buttons, while leaving the silicon untouched.

Emulation performance, generation by generation

The RK3326 is a quad-core Cortex-A35 clocked to 1.5GHz with a modest Mali-G31 MP2 GPU, paired with just 1GB of DDR3. In practice that means everything up to the 16-bit era runs flawlessly. NES, SNES, Genesis/Mega Drive, Game Boy through Game Boy Advance, Master System, Game Gear, WonderSwan, PC Engine and Neo Geo all hit full speed in RetroArch, using cores like Snes9x, Genesis Plus GX and mGBA. Arcade emulation through FinalBurn Neo and MAME 2003 Plus handles CPS1, CPS2 and Neo Geo boards cleanly, which suits the low resolution well. PlayStation 1 is the real headline: PCSX-ReARMed runs the overwhelming majority of the PS1 library at full frame rate, which is the single biggest reason to own an RK3326 device. Above that line, honesty is required. Nintendo 64 is a lottery, with Mupen64Plus booting the simpler titles like Mario 64 and F-Zero X with dips while heavier games chug or glitch. Nintendo DS through DraStic is technically possible but cramped by the 480×320 screen and starved by the 1GB of RAM, so only a subset plays comfortably. PSP via PPSSPP is a stretch, where a handful of 2D-leaning games run and most 3D ones crawl. Dreamcast, Saturn and anything newer are effectively off the table. This is a machine you buy for its floor, which is excellent, not its ceiling.

Screen, build and controls

The 3.5-inch IPS display runs 480×320 at a 3:2 aspect ratio, a genuine upgrade over the original RGB10’s weaker panel with better colour and viewing angles. That 3:2 shape flatters GBA and PS1 but forces letterboxing on 4:3 systems like the SNES. The whole unit weighs about 143 grams and measures roughly 144mm wide, which makes it comfortable for smaller hands and cramped for larger ones over long sessions. A 3000mAh battery delivers a real-world five hours or so, short of PowKiddy’s optimistic eight-hour claim but enough for a commute or a lunch break. There is no internal storage, so a single microSD holds your games. Build quality is plastic but solid. Controls are where opinions split: you get a single top-left analog stick, a d-pad below the face buttons, and stacked L1/R1 and L2/R2 shoulder buttons. Those shoulder buttons are the weak point, mushy and awkwardly placed and widely panned by reviewers. The stick is not Hall effect, so expect eventual drift. For a device whose sweet spot is PS1 and 2D, the single stick barely matters; for N64 or PSP it is a real limitation.

Software and setup

Out of the box the RGB10S ships with PowKiddy’s own open-source Linux firmware, which works but feels dated and clumsy. Almost everyone reflashes it. The RK3326 has one of the best custom-firmware scenes of any budget chip: ArkOS is the go-to for its clean setup and reliability, while JELOS and its active successor ROCKNIX offer a more modern, frequently updated alternative with better shaders and scraping. Both are free, boot from a second microSD card, and turn the RGB10S into a far nicer machine than the stock software. One quirk to note is that on this specific model the analog stick axis can come out inverted under ArkOS, so you will want to follow the device-specific configuration notes when flashing. There is no muOS or OnionOS here, since those target different chips, but ArkOS and ROCKNIX cover everything this hardware can realistically do.

Price, value and who it is for

The RGB10S launched around $80, and that price is the whole argument. For the money you get a competent PS1-and-below handheld in a genuinely pocketable body with a good screen, dual-band WiFi and USB-C charging. But by 2022 the RK3326 was already old, and rivals like the Anbernic RG353 series offered more power and better ergonomics for not much more. The RGB10S makes sense as a cheap secondary device, a gift for a younger player, or a grab-and-go machine for someone who only cares about 2D and PlayStation. Anyone hoping to play N64, DS or PSP seriously should spend more and look elsewhere. Judged strictly as an inexpensive 16-bit-and-PS1 pocket emulator running ArkOS or ROCKNIX, it does its narrow job well.
