Ugoos AM6B Plus review

An Android 9 box with an S922X-J, Wi-Fi 6, gigabit Ethernet and two external antennas.

In brief

Two hundred and fifty-three dollars on October 25, 2026 for Android 9 — two versions older than the HK1 Box X4 runs — and no AV1, which the $96 Infomir has. What it does have is two external antennas, which nothing else here offers. Key figures: Android 9 TV box with a 12 nanometer Amlogic S922X-J hexa-core processor of four ARM Cortex-A73 and two Cortex-A53 cores and ARM Mali-G52 MP6 graphics, 4 GB of LPDDR4 memory and 32 GB of storage, Wi-Fi 6 dual band with MIMO and RSDB, gigabit Ethernet, USB 3.0, Bluetooth 5.0, 4K H.265 HDR, over-the-air updates, supplied with an infrared remote, two dual-band antennas, a 12 volt 2 amp adapter with a choice of plug, an HDMI cable and a manual. Amazon.com had an offer at $253 on October 25, 2026.

What the maker puts in writing

Two external antennas, which nothing else here has

2 Dual-Band Antennas.

The Ugoos SK1 Lite at $299.90 publishes “2* Built-in WIFI Antennas”. Every other listing on this shelf is silent on the subject.

And a box behind a television is the worst place for an internal antenna. Two advantages follow from putting them outside.

Position. An external antenna can be angled upward and away from the cabinet. An internal one is wherever the board puts it — frequently behind a metal shield, inside a case, behind a television.

And gain. An external whip is physically larger than a trace on a circuit board, so it couples more energy from the air.

The bullet adds “MIMO RSDB Technology” — multiple-input multiple-output with simultaneous dual-band operation, so the box can use 2.4 and 5 GHz at the same time rather than choosing.

If your router is two rooms away, this is the box on the shelf built for that.

But it runs Android 9, and that is the reservation

Android 9.0. On this shelf the versions run:

9 — this, $247.69 10 — Formuler, $121.43 11 — HK1, $78.62 14 — Ugoos SK1 Lite, $299.90

So the second-most expensive box runs a version two behind one at less than a third of the price.

Why it matters: streaming applications progressively raise their minimum Android version, and when one passes your box’s, the app will not install or will stop updating. Security patches follow the same curve.

What mitigates it: the listing publishes an OTA updater, “so you no need to update firmware manually” — so Ugoos can ship fixes. What that cannot do is raise the Android version beyond what the chipset vendor supports.

And there is no AV1, which the ninety-nine-dollar box has

This publishes “4K H.265 HDR”. The Infomir at $99 publishes “modern HEVC and AV1 codecs”. The Ugoos SK1 Lite publishes “AV1, VP9, H.265, H.264, MPEG-4/2/1”.

AV1 is in use now. YouTube serves it widely and Netflix uses it, because it delivers comparable quality at twenty to thirty percent lower bitrate.

A box without hardware AV1 decoding has two fallbacks and both cost you: software decoding, which stutters and heats the chip, or requesting an older codec, which means a lower-quality stream at the same bandwidth.

The cause is the silicon. The S922X-J is a capable part that predates AV1 hardware decoding; the S928X-K in the dearer Ugoos includes it.

So the $148 between the two Ugoos boxes buys AV1, Android 14 and Wi-Fi 6E — which, read that way, is a more coherent gap than the price suggests.

The chipset is genuinely the better-built kind

Amlogic S922X-J with 12nm, Quad core ARM Cortex-A73 and dual-core Cortex-A53… ARM Mali-G52 MP6 GPU.

Three things worth drawing out.

A73 cores are performance cores, where most boxes on this shelf use A55 or A35 efficiency cores — the HK1 publishes quad A55, the Infomir quad A35. Four A73s plus two A53s is a “big.LITTLE” arrangement: heavy work on the fast cores, background work on the efficient ones.

Twelve nanometers is the fabrication process, and it is published nowhere else here. A smaller process means less power and less heat for the same work — which the bullet connects to directly: “excellent heat-dissipation, never worry about buffering and overheat”. Heat is the commonest cause of a box becoming sluggish after an hour.

A Mali-G52 MP6 is six graphics cores, against the G31 MP2 — two cores — in both the HK1 and the Formuler.

And the box contents are the fullest on the shelf

Ugoos AM6B Plus, IR Remote, 2 Dual-Band Antennas, 12V 2A Power Adapter (US/EU/UK or AU Plug), HD-MI Cable, English User’s Manual.

Six items, and the choice of power plug is published — which no other listing here mentions.

One thing to note about the remote: it is IR, meaning infrared, which needs line of sight to the box. So this cannot live inside a closed cabinet. The Apple TV’s Siri Remote and the voice remotes on the Xiaomi and ONN use radio and do not have that constraint.

Wi-Fi 6, gigabit Ethernet and USB 3.0 complete a connectivity set only the SK1 Lite matches — and gigabit plus USB 3.0 is the pair that matters for playing high-bitrate files off local storage, where a 4K remux can exceed 100 Mbit/s.

What is not published

No HDR format. “HDR” appears without naming Dolby Vision or HDR10+ — the two incompatible dynamic-metadata formats. Xiaomi at $94.99 and Apple at $234.99 publish both, which means matching any television.

No audio format. The Xiaomi publishes Dolby Audio and DTS:X, the Apple Dolby Atmos, the Infomir eight-channel Dolby Digital Plus, the SK1 Lite nothing either. On a box feeding a surround system, that is the figure to want.

No HDMI version, where three boxes here publish 2.1.

No optical output, which the SK1 Lite has — and which is how you feed an older amplifier without going through the television.

294 g and 117 × 117 × 20 mm are published.

What gets asked most

How much does Android 9 cost me?

Future app compatibility, and it is the one serious reservation about this box. It publishes "Android 9.0 Amlogic S922X-J TV Box" — and on this shelf the versions run 9 (this, at $247.69), 10 (Formuler, $121.43), 11 (HK1, $78.62) and 14 (Ugoos SK1 Lite, $299.90). So the second-most expensive box runs a version two behind one at less than a third of the price. Why it matters: streaming applications progressively raise their minimum Android version, and when one passes your box’s, the app simply will not install or will stop updating. Security patches follow the same curve. Android 9 dates from 2018, which is a long time in platform terms. What mitigates it: the listing publishes an OTA updater, so Ugoos can ship firmware — and Ugoos has a reputation for supporting its boxes longer than most. But it cannot update the Android version itself beyond what the chipset vendor supports.

Why do external antennas matter?

Because a metal-cased box behind a television is the worst possible place for an internal antenna, and this is the only product here with external ones. The contents list publishes "2 Dual-Band Antennas" — where the Ugoos SK1 Lite at $299.90 publishes "2* Built-in WIFI Antennas" and every other listing is silent. Two advantages follow. Position: an external antenna can be angled upward and away from the cabinet, where an internal one is wherever the board puts it, frequently behind a metal shield and a television. And gain: an external whip is physically larger than a trace on a circuit board, so it couples more energy. The bullet adds "MIMO RSDB Technology" — multiple-input multiple-output with simultaneous dual-band operation, meaning the box can use 2.4 and 5 GHz at the same time rather than choosing. If your router is two rooms away, this is the box on the shelf built for that.

Does the missing AV1 support matter at this price?

Yes, and it is the oddest omission here. This listing publishes "4K H.265 HDR" and names no AV1. The Infomir at $99 publishes "modern HEVC and AV1 codecs" and the Ugoos SK1 Lite at $299.90 publishes "AV1, VP9, H.265, H.264, MPEG-4/2/1". AV1 is in use now: YouTube serves it widely and Netflix uses it, because it delivers comparable quality at twenty to thirty percent lower bitrate. A box without hardware AV1 decoding has two fallbacks, and both cost you — software decoding, which stutters and heats the chip, or requesting an older codec, which means a lower-quality stream at the same bandwidth. The cause is the chipset: the S922X-J is a capable part that predates AV1 hardware decoding, where the S928X-K in the dearer Ugoos includes it. So the $148 between the two Ugoos boxes buys AV1, Android 14 and Wi-Fi 6E.

Who should pick this one, among streaming boxes and sticks

A weak Wi-Fi signal — the external antennas are the one thing nothing else here offers
