Mangmi Air X vs Anbernic RG556: four systems apart

A 5.5 inch 1920 x 1080 Android handheld with Hall-effect sticks and a fan, for less than two hundred euro, is the slot most of this market is fighting over. Two machines claim it. The Mangmi Air X arrived in October 2025 at a budget price and the Anbernic RG556 has been the default answer since March 2024, because it put an AMOLED panel on a Unisoc chip and sold it for less than a Steam Deck.

We grade both on the same eighteen-system sheet, and on the ten systems from Game Boy to PSP they carry the same letter. The decision is not there. It sits at one boundary - GameCube, Wii, Nintendo 3DS and PlayStation 2 - and at the price of getting either machine into a European living room. Those two questions have opposite answers, which is why this page exists.

Ten systems identical, then a cliff

Begin with what the two agree on. Game Boy, NES, Sega Genesis, Game Boy Advance, SNES, PlayStation 1, Nintendo DS, Nintendo 64, Dreamcast and PSP all carry an A on both sheets. If your library is 8- and 16-bit with a side of PS1, N64 and Dreamcast, the comparison is already over: buy the cheaper one where you are and spend the difference on games. Neither device is the only option in this bracket either - we have run the RG556 against its RG557 sibling and the Air X against the Anbernic RG406H through the same eighteen systems.

The first crack is Saturn, where the RG556 holds an A and the Air X drops to B. Still playable, but it is the first sign that the smaller chip is being asked for something it cannot quite give. After Saturn the grades stop shading and start jumping by whole bands:

Read the playable column - B or better, the line we use on every page - and it is eleven systems against fifteen. The four in the gap are GameCube, Wii, Nintendo 3DS and PlayStation 2: between them the largest libraries of the 2000s, and none of them is a case of the Air X running them slightly worse. A D+ on 3DS and a D on PlayStation 2 are not slow versions of the games you wanted; they are the reason people describe a handheld as "doing PSP" and stop there.

Above the gap the two agree again, and neither agreement helps. Wii U, Switch and PlayStation 3 are out of reach for both, the RG556 topping out at D- on Wii U while the Air X sits at F on all three. Nobody should buy either of these for post-2017 Nintendo software.

The chips behind the letters

The Air X runs a Qualcomm Snapdragon 662: four Cortex-A73 and four Cortex-A53 cores at 1.8 to 2.0 GHz, an Adreno 610 at 1050 MHz, 4 GB of LPDDR4X and 64 GB of eMMC storage. It is a 2020 handset chip in a 2025 handheld, and it is good at exactly what those chips are good at - 2D systems, PlayStation 1, N64, Dreamcast, PSP. The ten A grades are that list.

The RG556 runs a Unisoc Tiger T820 on a 6 nm process: one Cortex-A76 at 2.7 GHz, three more at 2.3 GHz, four A55s at 2.1 GHz, a Mali-G57 MP4 at 850 MHz, 8 GB of LPDDR4X and 128 GB of UFS 2.2. It is not a flagship and nobody should describe it as one, but it is a class above the 662, and it is the chip that made a sub-$200 handheld take PlayStation 2 seriously. The grade sheet is the receipt for that claim, in letters rather than adjectives.

Memory and storage complete the gap. Double the RAM is the headroom the four contested systems need, and UFS 2.2 against eMMC is a different order of storage rather than a bigger one. We have not measured load times on the two devices, so treat the storage comparison as a specification; treat the memory comparison as the reason the RG556 can be asked to emulate a system the Air X cannot.

The same resolution is not the same panel

Five and a half inches against 5.48, both 1920 x 1080 at 16:9 and 60 Hz, both 400 ppi by the catalogue's own figures. That pixel density is why the two get compared at all: nothing about the Air X's picture is lower-resolution, and no game will look soft on it next to the RG556.

The technology is the difference. The Air X uses an IPS panel under OCA-laminated tempered glass; the RG556 uses AMOLED. In a lit room that is a footnote. In a dark room it is the whole picture: an AMOLED switches pixels off, so the black bars on either side of a 4:3 game are actually black and a horror game or a space shooter keeps its contrast. The IPS panel is grey in the same scene. If most of your play happens after dark, that one line decides the purchase more than any letter grade.

Both are touchscreens, and on both the touch layer is mostly for Android itself rather than for the emulators.

Weight, battery and the buttons

286 grams against 331, and 203.47 x 87.39 x 16.80 mm against 223 x 90 x 15 to 25 mm. The Air X is 19.5 mm narrower and 45 grams lighter. Neither is a pocket device, but the Air X is the one that goes into a bag without a second thought.

The batteries are 5000 mAh and 5500 mAh, ten percent apart. Anbernic publishes eight hours of play and a 3.5 hour charge at 5V/2A; Mangmi publishes no runtime figure, so there is nothing honest to say beyond capacity. Both are actively cooled: Anbernic describes a high-speed fan and a heat pipe, and the catalogue records a heatsink, fan and ventilation cutouts for the Air X.

The controls are closer than the price gap suggests. Both use Hall-effect thumbsticks, which is the part that used to fail on cheap handhelds. The RG556 adds Hall triggers, a vibration motor and USB-C DisplayPort output for 1080p on a television. The Air X's own specification lists no rumble and no video output, and adds a gyroscope and a microphone. If you intend to dock to a TV, that is another line the Air X loses.

What the makers charge

The tracked figures come from the public price sheet we import nightly, and both need a word of explanation. Mangmi charges $99.99 for the Air X today, so the $80 this catalogue carries is twenty dollars under what a checkout asks for, the one direction that misleads a buyer, and every page that prints it now says so. Anbernic is the opposite case: its own store listed the RG556 at $179.99 on 29 October 2026 against a regular price of $184.99, which is four dollars above the tracked figure. Anbernic's sale calendar moves constantly, so read the live number before you order rather than trusting any figure on any site, including this one.

What a European can actually buy

This is where the two stop being symmetrical. The Air X has a verified EU listing: an EU shop stocks it at €144.95 with VAT included, which is the price paid at the door with no import fees added on delivery, and it was in stock when we checked on 3 November 2026.

The RG556 has no verified EU listing. Anbernic's own product page offers an EU shipping origin alongside China and the United States, but we hold no EU shop listing for it that we have checked, so there is no landed euro price we can quote. Buying it from Anbernic directly means importing: VAT, duty and the battery and chemical fees are charged on delivery, and that can add a fifth to the figure before the courier hands it over. On a $179.99 handheld that is not a rounding error, and it is the difference between the two devices being eighty dollars apart and being twice the price apart.

Which reframes the question. For a European, the Air X is not the budget alternative to the RG556; it is the only one of the two that has a price you can hold the seller to.

Verdict: the four systems are the whole argument

The Mangmi Air X is the better buy for most people, and the reason is not the spec sheet - it is that €144.95 with VAT already paid is a real price in Europe while the RG556's is a figure you convert and then add tax to. On the ten systems from Game Boy to PSP the two are identical, the Air X is lighter and narrower, and nothing about its picture is a downgrade in resolution.

Buy the RG556 instead if any one of GameCube, Wii, Nintendo 3DS or PlayStation 2 is the reason you are shopping. It is the only device of the two that runs them, the letters are B+, B, B+ and B rather than C, C+, D+ and D, and that is a genuine library difference: a handheld that plays GameCube and PS2 at B grade is a different machine from one that stops at PSP, whatever the price. Add the AMOLED panel and the DisplayPort output and the case for the imported device gets stronger, not weaker.

What neither will do is Wii U, Switch or PlayStation 3, and no amount of memory or firmware will change that. If those systems are on your list, the honest answer is that this is the wrong price bracket and both of these handhelds are the wrong purchase.
