MESWAO 15.6" MES-B3 Black 2025

The MESWAO MES-B3 is a niche tablet with a giant, smooth 15.6-inch screen and class-leading battery life in a nice metal body. Performance is its Achilles heel, with a processor that struggles under heavy loads. At $410, it's a terrible all-around tablet but a brilliant, purpose-built device for musicians or fixed-location business use where screen size and endurance matter more than raw speed.

Under the hood is a MediaTek Helio G99 chip, which is an honest, if aging, octa-core processor. We're going to be straight with you: in our database, the CPU performance lands in the bottom 10% of all tablets. It's built on an older 6nm process and designed for budget phones and entry-level gaming. What that means in real life is that Android 14 feels fine swiping around, and apps open without a ton of fuss thanks to that 8GB of RAM, but you're not going to mistake this for an iPad Pro. Light gaming is doable, but the GPU is even weaker than the CPU, sitting near the very bottom of our charts, so don't expect to crank up Genshin Impact. This thing is built for a static, purpose-driven life, not for pushing frames.

If you're cross-shopping a Samsung Galaxy Tab S11 or an Apple iPad Pro, just stop. Those are in a completely different universe for processing power and software polish, and they cost double or triple the price. The closest real fight is something like the Lenovo Idea Tab Pro. The Lenovo will run circles around the MESWAO in raw speed and has a better software experience for multitasking. But it's smaller, and its battery won't touch this thing's marathon endurance. Then there's the Xiaomi Pad series, which often packs a better screen and speakers into a similar budget range but with a processor that's just okay. The MES-B3 trades all-around competence for two extreme strengths: sheer screen real estate and a battery that just won't quit.

At $410, the value proposition is a total balancing act. You're paying for the monstrous 12000mAh battery and that genuinely large, 120Hz screen in a metal body. On the spec sheet alone, dropping that much cash on a tablet with a bottom-tier processor might feel like a mistake. But the real comparison isn't other $400 tablets, it's a tricked-out Echo Show 15 or a dedicated portable monitor paired with a cheap phone. For a fixed-location, single-use device like a demo unit or a music stand, the battery and screen size are features nobody else offers at this price. For a general-purpose tablet, though, you can find significantly more horsepower for the same money.

The MESWAO MES-B3 is a tablet that makes you do a double take. It's got a massive 15.6-inch screen, which is basically laptop territory, and stuffs it into a device running Android 14. Right away, you know this isn't for someone looking to one-hand a Kindle on the subway. This is for a very specific person, like a musician wanting a giant digital sheet music stand, someone setting up a dedicated kitchen recipe hub, or a business looking for a sleek point-of-sale demo unit. At around $410, it's positioned in a weird, interesting gap between premium smaller tablets and cheap Chromebooks, and that's where the whole conversation gets fun.

If you need this for actual, daily productivity like split-screen multitasking with heavy documents, spreadsheets, and constant Slack messages, walk away. Our scoring places it at rock bottom for productivity, and that big screen just highlights the slow processor's limits. You'll be tapping your fingers waiting for things to load. Get a cheap Chromebook or a used Lenovo Idea Tab instead. Also, if it's for a kid who wants to play popular mobile games, this will just lead to frustration. The GPU is a decade behind the curve, and you'll both be miserable. Save the money and get a last-gen iPad for a vastly superior gaming and app experience.

If you're a musician tired of squinting at a 10-inch screen on a music stand, stop looking. This is your device. The large A4-sized display is perfect for displaying full pages of sheet music, and the incredible battery means you won't have a cable snaking across the stage. Similarly, for a fixed business-use case like a POS display or a permanent kitchen companion for recipes and videos, the MES-B3 makes a ton of sense. It's a workstation tablet that asks to be put down and left in one spot.
