Powkiddy RGB20S & V90 vs. R36S: Which Budget Handheld Should You Buy in 2026?

If most of your play happens in short stretches, fifteen minutes on a train or in bed after the house goes quiet, the buttons under your thumbs matter more than any line on a spec sheet. Below, I compare the chips, the control layouts, what each handheld can actually emulate, and what arrives on the microSD card across the 2Bluebox R36S, Powkiddy RGB20S, and Powkiddy V90.

Powkiddy RGB20S vs. R36S: Same RK3326 Chip, Flipped Controls

The Powkiddy RGB20S and 2Bluebox R36S ($79.99) share the Rockchip RK3326, 1GB of DDR3L RAM, and a 3.5-inch 640x480 IPS panel. The difference is the faceplate: the R36S puts the D-pad and ABXY buttons on top and the two analog sticks below.

According to the RetroCatalog Powkiddy RGB20S specification sheet, the RGB20S runs a quad-core Rockchip RK3326 at 1.5GHz with 1GB of DDR3L RAM and a 3.5-inch 640x480 IPS screen in a vertical, Game Boy-style body. That's the same core hardware inside the R36S, so on paper both handhelds run the same systems at the same speed.

Where they split is the faceplate. On the RGB20S, the two analog sticks sit high, just under the screen, and the D-pad and ABXY buttons sit below them toward the bottom edge of the shell. If you're weighing the two, buyer threads like this r/SBCGaming discussion comparing the RGB20, R36S, and RG35XX are worth a read before you pick.

As we cover in our R36S review, the R36S keeps the same internals and swaps the control zones:

• Same core, controls swapped: The R36S uses the Rockchip RK3326 (1.5GHz quad-core Cortex-A35), a Mali-G31 MP2 GPU, 1GB of DDR3L RAM, and a 3.5-inch 640x480 IPS panel (228 PPI). The D-pad and ABXY buttons move up under the screen, and the two clickable L3/R3 analog sticks move down.
• Firmware already set up: Every 2Bluebox R36S ships with ArkOS 2.0, a Linux-based handheld system that boots straight into the game menu, configured and ready on the card. See how it stacks up in our guide to the best retro handheld consoles in 2026.

Table 1 lines up the published specs of the 2Bluebox R36S ($79.99), the Powkiddy RGB20S, and the folding Powkiddy V90.

"Tested on our unit" means we checked it on a device we own. "Manufacturer spec" means the maker states it and we haven't verified it ourselves. "Community reports" means players report it, and results can vary.

The RGB20S question comes down to layout, because the chip is identical. The V90 is a different story, since its chip sets hard limits on what it can play.

Powkiddy V90 vs. R36S: What a 32MB Clamshell Can and Can't Play

With a single-core 533MHz Allwinner F1C100S and 32MB of RAM, the Powkiddy V90 handles 8-bit and most 16-bit games. The 2Bluebox R36S ($79.99), with 1GB of RAM and a quad-core RK3326, reaches PS1, GBA, and lighter N64 and PSP titles.

The V90's folding shell looks a lot like a Game Boy Advance SP, and that's most of its appeal as a travel handheld. Open the RetroCatalog Powkiddy V90 hardware datasheet, though, and the gap between the V90 and the 2Bluebox R36S ($79.99) is wide:

• 32MB vs. 1GB of RAM: RetroCatalog lists a single-core Allwinner F1C100S (ARM926EJ-S at 533MHz) with 32MB of DDR RAM and no 3D GPU. The R36S has 1GB, 32 times as much, plus a quad-core CPU and a Mali-G31 GPU. SNES games that use extra cartridge chips, like Star Fox and Super Mario World 2: Yoshi's Island (Super FX) or Super Mario RPG (SA-1), are the usual slowdown spots on this class of chip, and 3D PS1, N64, Nintendo DS, Dreamcast, and PSP games are out of reach.
• 320x240 vs. 640x480: The V90's 3.0-inch 320x240 screen has 76,800 pixels, while the R36S panel has 307,200, four times as many. SNES (256x224) fits the V90 screen at 1x with thin borders, but GBA (240x160) either plays small or gets stretched at an uneven scale that softens sprites. On the R36S, both scale up at a clean 2x.

Table 2: What Each Handheld Can Play and How It Saves

The V90 has one more habit worth knowing before you buy. Its slide power switch cuts power directly, so switching off mid-game without exiting first can corrupt files on the microSD card, a warning you'll see repeated for budget handhelds with hard power switches. On the 2Bluebox R36S, ArkOS 2.0 gives you a menu shutdown that closes files first, plus FN shortcuts that keep your saves safe:

1. Save before you stop: In any GBA, SNES, or PS1 game, press FN + R1 to save a state instantly, then FN + L1 to load it later.
2. Exit the game cleanly: Press FN + START twice to close the emulator and write your in-game battery save (the .srm file) to the 64GB card.
3. Shut down from the menu: Press START → Quit → Shutdown System so ArkOS closes everything before the screen goes dark.

If you want the RK3326's full library in a pocket-sized shell with the D-pad up top, the 2Bluebox R36S ($79.99) ships with ArkOS 2.0 set up and the 15,768-file card ready to play:

D-Pad on Top vs. Sticks on Top: Which Layout Fits Retro Games?

NES, SNES, Game Boy, Genesis, and most arcade games are built around a D-pad. On the 2Bluebox R36S ($79.99), the D-pad sits on top, so your left thumb works from the main spot while the lower shell fills your palms.

Think about where your hands go on a vertical handheld. Your index fingers curl onto the shoulder buttons, the lower corners of the shell rest in your palms, and whatever sits in the upper control zone gets the most comfortable thumb position.

On the RGB20S, that upper zone goes to the analog sticks, which makes sense for PS1 and N64 games built around them. For D-pad games, your thumbs work lower on the shell, closer to the bottom edge, with less plastic left underneath to grip. Over a long Street Fighter Alpha 3 or Metroid Fusion session, that lower reach is the part some players find tiring.

• D-pad and ABXY up top: On the R36S, the D-pad and face buttons sit right under the 3.5-inch screen, so your thumbs rest in a relaxed arc and the lower half of the shell fills your palms. The two analog sticks are still there below for the PS1, N64, and PSP games that use them.
• Same four shoulder buttons: Both handhelds have L1, L2, R1, and R2 on the back edge, so the difference you'll feel day to day is on the front of the shell.

5V Charging, MicroSD Cards & Game Lists: Buying the R36S From 2Bluebox

Charge the 2Bluebox R36S ($79.99), like most budget RK3326 handhelds, from a standard 5V USB-A charger because it lacks USB-C Power Delivery support. Buying from 2Bluebox adds a public 15,768-file game list, a checked Dual-RAM board, and a 30-day replacement guarantee.

One hardware rule applies whichever handheld you end up with. As the Handhelds Wiki R36S Buying Guide explains, budget RK3326 handhelds don't have a USB-C Power Delivery chip on the charging port, so they expect plain 5V power.

Back when I used to pop open SNES shells to check the PCB and scrub the brass pins with 99% isopropyl alcohol and a Q-tip, I learned that the label on the outside tells you very little. A handheld listing works the same way: what counts is the board inside the shell and the files actually sitting on the microSD card.

Table 3: Buying the R36S From 2Bluebox vs. Marketplace Listings

• What's on the card: Every 2Bluebox R36S ships with a 64GB microSD card set up with ArkOS 2.0. When we exported the list from our R36S card, it held 15,768 game files, and after removing duplicates and broken files, 12,805 unique playable games remain, all searchable on our R36S games list before you order.
• What's inside the shell: Every unit uses the Dual-RAM RK3326 board (1GB DDR3L) and a removable 3200mAh battery, backed by 2Bluebox LLC (1500 N Grant St, STE N, Denver, CO 80203) and our 30-Day Hardware & MicroSD Replacement Guarantee.

Try explaining to a seven-year-old why a 1990s game won't save wherever she stops. That's a conversation I have at home with my daughter, and it's why FN + R1 save states on a card that's already set up matter more to me than any spec on this page.

Verdict: Should You Buy a Powkiddy Handheld or the 2Bluebox R36S in 2026?

Pick the 2Bluebox R36S ($79.99) for pocket D-pad games: the RGB20S's RK3326 chip, D-pad on top. Skip it for TV play (2Bluebox Retro Game Stick 4K Pro, $59.98) or PS2 on a Windows PC (2Bluebox Portable HDD Super Console, $64.99).

Conclusion

The Powkiddy RGB20S and Powkiddy V90 both helped put cheap Linux handhelds in a lot of pockets. The V90's 32MB chip and 320x240 screen top out around 8-bit and lighter 16-bit games, and the RGB20S hands its best thumb position to the analog sticks while most retro games lean on the D-pad.

The 2Bluebox R36S ($79.99) keeps the same RK3326 power, puts the D-pad where your thumb expects it, and arrives with ArkOS 2.0 and a 15,768-file card you can check title by title before you buy. If your games live on the living-room TV, the Retro Game Stick 4K Pro is the better fit, and if you're after PS2 or GameCube, the Portable HDD Super Console on a Windows PC is the one to get.

Check the game list, use a 5V USB-A charger, and Press Start.
