Supersonic SC-2420VTV 24"
Dual AC and 12V car DC power options make this 24-inch HD LED TV uniquely suited for both home and RV use, with a 3000:1 contrast ratio and three HDMI ports for modern devices. The VIDAA smart interface provides direct streaming access to Netflix and YouTube, while legacy RCA inputs support older gaming consoles and DVD players. This set is best for RV owners or anyone needing a compact, portable screen that can run directly off a vehicle's power system.
Snapshot
The 30-Second Version
The Supersonic SC-2420VTV is a 24-inch smart TV built for RVs and portable setups, with dual AC/DC power and a lightweight 2260g frame. The 1366 x 768 panel and 180 nits brightness put it at the very bottom of our picture quality rankings, so don't expect much visually. At USD 180-200 (Newegg has the best US price), it's worth it only if you need the 12V car power option. Everyone else should look at a TCL or Roku for similar money and a much better picture.
Pros & Cons
Pros
- Dual AC/DC power with included cables makes it genuinely portable
- Three HDMI ports plus RCA input covers modern and legacy devices
- VIDAA OS gives you Netflix, YouTube, Disney+, and Prime Video built in
- Lightweight at 2260g, easy to mount or move
- 3000:1 contrast ratio is decent for a budget panel
Cons
- 1366 x 768 resolution is dated, even at 24 inches
- 180 nits brightness struggles in anything but a dim room
- Picture quality ranks at the very bottom of our database
- Wi-Fi 4 is old and slow for streaming
- Smart platform performance is well below average
The proof
Performance
Let's talk about what you're actually getting with that 1366 x 768 panel. This is HD, not Full HD, and at 24 inches, that resolution is... fine for casual viewing. Text will look a bit soft if you're using it as a monitor, but for watching shows from across a room or in an RV, it gets the job done. The 180 nits brightness is where things get rough. In a dim room, you'll be okay. In a bright room or near a window, you'll be squinting. Our database puts the display quality dead last among comparable products, and the picture quality doesn't fare any better.
The 3000:1 contrast ratio is actually the one spec that isn't terrible. It's not going to blow you away, but it's better than a lot of cheap panels manage. The 60Hz refresh rate and 9.5ms response time are standard for budget TVs, and casual gaming will be playable. Just don't expect competitive-level responsiveness. The 42W power draw is reasonable for a TV this size, and it matters when you're running off a battery in an RV.

vs Competition
Stacked against the competition, the Supersonic SC-2420VTV is playing a completely different game. The TCL QM6K Series 55QM6K and the Roku Plus Series 55R6C7 are both 55-inch TVs with proper 4K panels and HDR support. They're bigger, brighter, and better in every measurable way except portability. The Samsung M80H and Hisense QD7 Series 65QD7QF are even further ahead on picture quality, with quantum dot tech and much higher brightness ratings. The Sony BRAVIA 3 II K43XR30M2 is a 43-inch option that would be a much better choice for a small room if you don't need the 12V power.
The trade-off is obvious: you're giving up picture quality, resolution, and smart platform performance to get a TV that can run off a car battery and weighs just over 2kg. None of those competitors can do that. So the comparison isn't really fair, but it does highlight what you're sacrificing. If portability isn't a hard requirement, any of those other TVs will give you a dramatically better viewing experience.

Price
Value & Pricing
Pricing on this one is all over the place depending on where you shop. In the US, you're looking at USD 180 to USD 200 across three listings, and Newegg has the best deal at the lower end of that range. Canadian buyers will see a wider spread, from CAD 273 to CAD 312, so it's worth shopping around before you commit. The Japanese listing at JPY 50,514 and the Mexican listing at MXN 4,806 are single-vendor situations, so you don't have much room to negotiate there.
Is it worth it? For the right use case, yes. You're paying for the portability and the dual power setup, not the picture quality. If you need a TV that runs off a car battery and has smart features built in, this is one of the few options at this price point. But if you're just looking for a cheap small TV for a kitchen or bedroom, you can find better picture quality for similar money from more established brands.

Overview
The Supersonic SC-2420VTV is a 24-inch smart TV that's clearly built for a specific niche: RVs, campers, spare rooms, and anywhere you need a small screen that can run off a 12V car outlet. The included AC/DC adapter is the headline feature here, and honestly, that's the main reason this thing exists. You're not buying this for the picture quality, and the specs make that pretty clear right away.
At its core, this is a 1366 x 768 HD panel with a 60Hz refresh rate and a 9.5ms response time. The VIDAA smart platform gives you access to Netflix, YouTube, Disney+, and Prime Video, which covers most people's streaming needs. Three HDMI ports and an RCA input mean you can hook up everything from a modern streaming stick to a retro gaming console, which is a nice touch for a budget TV.
Who's this actually for? Someone who needs a small, portable TV that can survive life on the road or in a workshop. The 2260g weight makes it easy to move around, and the dual power options are genuinely useful. But if you're looking for a primary living room TV, even for a small apartment, you should probably keep scrolling. This is a utility purchase, not a home theater upgrade.
Common Questions
Q: Can this TV run off a 12V car or RV battery?
Yes, that's the main selling point. The SC-2420VTV includes both an AC adapter for home use and a DC cable for 12V power sources like car outlets or RV batteries. The 42W power draw is low enough that it won't drain a typical RV battery too quickly, though you'll still want to be mindful of how long you run it without the engine or a solar setup charging things back up.
Q: Is the 1366 x 768 resolution good enough for streaming?
It depends on your expectations. At 24 inches, 1366 x 768 is watchable for casual viewing, but it's not Full HD, so you won't get the sharpness of a 1080p or 4K panel. Streaming services will work fine through the VIDAA OS, but the picture will look softer than what you're used to on a modern TV. If you're sitting more than a few feet away, it's less noticeable.
Q: How does the VIDAA smart platform compare to Roku or Google TV?
VIDAA is a lightweight smart TV OS that covers the basics: Netflix, YouTube, Disney+, Prime Video, and a few other apps. It's not as polished or fast as Roku or Google TV, and the app selection is more limited. Our smart platform score puts it well below average, so expect some sluggishness in the menus. If you already have a streaming stick, you might prefer using that through one of the HDMI ports instead.
Q: Can I use this as a computer monitor?
Technically yes, but it's not ideal. The 1366 x 768 resolution means text will look soft and you'll have limited screen real estate. The 9.5ms response time is fine for basic productivity, but the 180 nits brightness will feel dim if you're used to a typical monitor. If you need a small display for a PC, you're better off with a dedicated monitor at this price point.
Who Should Skip This
Skip this if you're looking for a primary TV, even for a small room. The picture quality is the weakest we've seen in our database, and the 180 nits brightness will frustrate you in any room with natural light. If you want a small smart TV for a kitchen, bedroom, or dorm room, look at a 24 or 32-inch option from TCL, Hisense, or Insignia instead. You'll get a 1080p panel and better brightness for roughly the same money.
Also skip it if you care about smart TV performance. The VIDAA platform is functional but sluggish, and Wi-Fi 4 is outdated. If you're planning to stream 4K content or use demanding apps, this isn't the TV for you. And if you're a serious gamer, the 60Hz refresh rate and 9.5ms response time won't cut it for anything competitive. This is a utility TV for specific situations, not a general-purpose entertainment display.
Verdict
If you're outfitting an RV, camper van, or need a TV for a workshop or garage where AC power isn't always available, the Supersonic SC-2420VTV makes a lot of sense. The 12V DC option is the killer feature, and the included cables mean you don't have to hunt down adapters. The three HDMI ports give you flexibility for gaming consoles, streaming sticks, or a Blu-ray player, and the RCA input is a nice bonus for retro gaming setups.
For everyone else, this is a hard pass. The 1366 x 768 resolution, 180 nits brightness, and bottom-of-the-barrel picture quality scores mean you'll be disappointed if this is your main TV. Even as a secondary bedroom TV, there are better options from TCL, Hisense, or Roku that cost about the same and deliver a much better picture. Buy this for the portability, not the pixels.
