Broad emulation range
X35S lands in a crowded lane, which is exactly why the comparison with RGB20SX, RGB20 Pro, and RG-35XX Plus matters so much.
X35S looks most interesting when you treat it as a specific answer to a specific kind of retro player, not as a mythical one-device-for-everyone machine.
Before the review gets opinionated, here is the clean spec picture. This table is the reality check that keeps the rest of the write-up grounded.

If this review pulls you in, the fastest next rabbit hole is RGB20SX and RGB20 Pro, because those are the products most likely to clarify whether X35S is your real match or just your current curiosity.
X35S pairs the hardware with 3.5 inch, IPS, 60 Hz, 640 x 480, 4:3, and 228.57 PPI. That is the kind of detail stack retro buyers should linger on, because a handheld can be technically capable and still feel wrong if the aspect ratio, sharpness, and scaling story are off. The screen protection is listed as Tempered Glass, a small clue that often hints at how polished or rough the front face might feel in daily use.
The controls are described with Cross Lower placement, Dual thumbsticks (L3/R3) Upper placement, 4 Buttons, L1, R1, L2, R2, and Power, Reset, Volume +-. That matters more than many spec sheets admit, because the difference between a fun handheld and a fatiguing one often shows up in the D-pad, shoulder shape, and how naturally the thumbs settle into place. This is where a retro handheld stops being abstract and starts becoming a piece of physical furniture for your hands.
The 4:3 aspect ratio adds another layer to the story. Retro gaming screens are never neutral. They reward some libraries, punish others, and always whisper a preference about how the device expects to be used.
X35S is currently tracked around 60.0 and lands in the $050 - $075 pricing band. Price does not just change whether a device feels affordable. It changes what kinds of flaws buyers are willing to forgive.
The spreadsheet points shoppers toward Powkiddy for availability. That matters because storefront quality, shipping confidence, and after-sales expectations often shape the emotional experience of a purchase before the box even arrives.
Every handheld makes tradeoffs somewhere, even when the spreadsheet leaves them unstated. The smartest shortlist is usually the one that sees the flaw clearly and decides it is either acceptable or disqualifying before the credit card comes out.
X35S is best framed as a machine for buyers who want a serious all-rounder with room for tougher systems. The smartest handheld purchases usually happen when the buyer matches the hardware to a play style instead of falling for the loudest marketing line.
The vertical shape matters here because it changes comfort, portability, and the kind of nostalgia the device leans into. The fact that it runs Linux also affects what kind of setup work, app ecosystem, and tinkering ceiling buyers should expect.
The release timing listed as 2024 / 08 helps place it in context. A handheld can be exciting because it is current, but it can also be relevant because it still makes sense at today's street price.
| Console | Angle | Price | Performance | Why Click Through |
|---|---|---|---|---|
RGB20SX PowKiddy | Brand Neighbor | 60.0 | ⭐️⭐️⭐️⭐️⭐️½ | same operating system, vertical layout, tracked around 60.0. |
RGB20 Pro PowKiddy | Brand Neighbor | 70.0 | ⭐️⭐️⭐️⭐️⭐️½ | same operating system, vertical layout, tracked around 70.0. |
RG-35XX Plus Anbernic | Closest Match | 64.0 | ⭐️⭐️⭐️⭐️⭐️ | same operating system, vertical layout, tracked around 64.0. |
RG-40XXV Anbernic | Closest Match | 60.0 | ⭐️⭐️⭐️⭐️⭐️ | same operating system, vertical layout, tracked around 60.0. |
X35S becomes much easier to judge once it is forced into the same room as RGB20SX, RGB20 Pro, and RG-35XX Plus. This is where a vague impression turns into a real buying decision, because each nearby rival throws a different kind of pressure on the table.
X35S versus RGB20SX is interesting because brand neighbor is the obvious angle. Compared with X35S, RGB20SX makes the more obvious play for readers who care about brand neighbor. RGB20SX is tracked around 60.0. Its overall rating is ⭐️⭐️⭐️⭐️⭐️½. X35S versus RGB20 Pro is interesting because brand neighbor is the obvious angle. RGB20 Pro sits close enough to X35S to make the comparison meaningful, but different enough to sharpen the buying decision. RGB20 Pro is tracked around 70.0. X35S versus RG-35XX Plus is interesting because closest match is the obvious angle. If X35S feels almost right but not quite, RG-35XX Plus is the sort of nearby detour that can completely change the shortlist. RG-35XX Plus is tracked around 64.0. In practice, its overall rating is ⭐️⭐️⭐️⭐️⭐️.
Comparison is the antidote to spec-sheet hypnosis. Once you stack the neighbors side by side, you stop asking which one is objectively best and start asking which one is best for your habits.
X35S is described with battery: 3000 mAh. Those are not background details; they shape noise, comfort, endurance, and whether the device feels eager to be used or mildly exhausting to keep fed. Audio is covered by Dual Stereo Front facing and Headphone Jack, which matters for sofa play, travel, and late-night sessions when speakers and headphone output can quietly make or break the experience.
Physically, the device is outlined by 81 mm x 126 mm x 22 mm, 177.0, Plastic, and Transparent Purple, Gray, Black, White, Orange. This is where you start picturing whether it is truly pocketable, only jacket-safe, or clearly a bag companion. The best portable devices earn their place in a routine. They are easy to reach for, easy to trust, and easy to put back down without feeling delicate.
The practical I/O story includes Internal & External MicroSD card, OTG, Bluetooth, USB-C Top facing, and Mini HDMI. These details matter because many retro buyers are also collectors, tinkerers, dock-and-TV players, or people with large libraries that need sensible storage and transfer options.
The heart of the machine is the RockChip RK3566. CPU duties are handled by Cortex-A55. Graphics are handled by Mali-G52 2EE. Memory is listed at 1 GB LPDDR4X. The sheet rates the overall performance at ⭐️⭐️⭐️⭐️⭐️½, or roughly 5.5 on the normalized scale.
The CPU side is described with 4 Cores, 4 Threads, and 1.8 GHz, which is more useful than brand names alone because it hints at how much headroom the handheld should have before emulator tuning gets annoying. On the graphics side, 2 Cores, 850 MHz, and ARM helps sketch the ceiling for heavier systems, upscale experiments, and shader curiosity.
X35S looks strongest with Game Boy (A), NES (A), Sega Genesis (A), Game Boy Advance (A), Super Nintendo (A), and PlayStation 1 (A), which gives the review something more tangible than a vague "good for retro" verdict. The listed emulation limit, N64, PSP & Dreamcast mostly playable but not all full speed, is the kind of line buyers should actually respect because it tells you where the romance ends and the compromise begins.
The middle tier of compatibility, including PSP (B-) and Sega Saturn (C), is where the buyer needs some honesty. These are usually the systems that separate a casual dabbler from a user who is happy tweaking emulator settings, testing cores, or accepting the occasional rough edge.
X35S leaves the strongest impression when you frame it as a recommendation for buyers who want a serious all-rounder with room for tougher systems. That framing keeps the review honest and stops the verdict from sliding into generic praise.
Broad emulation range is not just a catchy label here. It is the cleanest shorthand for why this device deserves attention. The compatibility profile around Game Boy (A), NES (A), Sega Genesis (A), and Game Boy Advance (A) gives it a concrete identity.
If the device sparks your interest, the smartest next click is usually RGB20SX, followed by RGB20 Pro, because that is where the shape of the market around it comes into focus. A useful verdict should leave the reader more curious, but also more precise.
