1onn. Google TV 4K Box (Walmart)US-Only Bargain★ 4.0/5≈ $20 (US)

The onn. Google TV 4K box is Walmart’s own-brand streamer, famous for being extremely cheap in the US — around $20 for full Google TV with 4K HDR — but it is US-only and not officially sold in Europe. We cover it for context and to steer European buyers to the right locally sold alternatives, since importing brings power, warranty and support issues. Here is what it offers, and what to buy instead in Europe.

Specifications

Spec onn. Google TV 4K Box
Max resolution 4K at 60fps
HDR Dolby Vision, HDR10, HLG
Audio Dolby Atmos passthrough
Wi-Fi Wi-Fi 5 (dual-band)
Storage ~8 GB
Ethernet Not built-in
OS Google TV (Play Store)
Price (obs. Jul 2026) ≈ $20 (Walmart, US only)

On paper it is remarkable value: full Google TV, 4K with HDR including Dolby Vision, for about $20 — but only in the US.

Using It: Real-World Performance

For its price, it performs well:

  • Cold boot to home screen: ~30 seconds.
  • Opening a major app: ~4–6 seconds.
  • Interface: the same clean Google TV experience as pricier devices.
  • Picture: genuine 4K HDR with Dolby Vision — unusual at the price.

The catch is entirely about availability. As a Walmart US exclusive, it is not sold in Europe, and importing means US power adapters, no local warranty, and potential app-region friction. Storage is also tight at ~8 GB. For a US buyer it is a superb budget pick; for a European buyer, a locally sold device is the sensible choice.

Our Verdict

The onn. Google TV 4K box is a genuine US bargain — full Google TV and 4K HDR with Dolby Vision for around $20 — but that is a US-only story. It is not officially sold in Europe, and importing brings power, warranty and region headaches that erase the value. If you are in the US, it is an easy budget recommendation; if you are in Europe, skip the import and buy a locally supported alternative like the Xiaomi TV Box S or a Fire TV Stick. Rating: 4.0/5 (US); not recommended to import.

Frequently Asked Questions

What is the Onn 4K box?

The onn. Google TV 4K box is Walmart's own-brand streaming box, known for being extremely cheap in the US, often around $20. It runs full Google TV with the Play Store and outputs 4K HDR. Its headline is value, but it is sold through Walmart in the US and is not officially available in Europe.

Can I buy the Onn 4K box in Europe?

Not officially. The onn. brand is a Walmart exclusive sold in the US, so it is not officially available in Europe, and imported units can face power, warranty and app-region issues. European buyers are better off with a locally sold Google TV device such as the Google TV Streamer or a Fire TV Stick, which have proper support.

Is the Onn 4K box good value?

In the US, yes, it is exceptional value — full Google TV with 4K HDR for around $20 makes it one of the cheapest capable streamers available. Outside the US the value case collapses once you factor in importing, adapters and lack of support, so its bargain status is really a US-only phenomenon.

Is the Onn 4K box as good as a Chromecast?

It is broadly comparable, running the same Google TV interface with 4K HDR, and it is cheaper in the US. Build quality and remote feel more basic, and it lacks some refinements. For US buyers it is a strong budget alternative to a Chromecast; for European buyers, locally sold devices are the sensible choice.

What is the best European alternative to the Onn 4K box?

For European buyers wanting a cheap Google TV experience, the Xiaomi TV Box S and the Chromecast with Google TV are the closest locally sold alternatives, with the Google TV Streamer as a step up. A Fire TV Stick 4K is also a great-value option. All are properly supported and easy to buy in Europe.
