Microsoft Foldable Black Review

The Jelly Comb B003B is a foldable Bluetooth keyboard with a built-in touchpad, made for maximum portability. Its standout feature is the all-in-one design, but it's held back by outdated Bluetooth 3.0. At around $102, it's expensive for its dated tech. Only recommend if you absolutely need a folding keyboard and a touchpad in one package for a non-iOS device.

Let's be real, the Jelly Comb B003B foldable keyboard is a weird little gadget. It's not trying to be your daily driver for a desktop PC. This thing is for the person who's constantly on the move with a tablet or smartphone and just can't stand typing on a glass screen for more than a few minutes. It's a portable typing solution that folds up to about the size of a large wallet, which is its entire reason for existing.

The core idea is simple: unfold it, pair it via Bluetooth (or plug it in with the included USB cable), and you've got a physical keyboard and a touchpad for your iPad, Android tablet, or even a lightweight laptop like a Surface. It runs on Bluetooth 3.0, which is pretty old tech by today's standards, but it gets the job done within a 10-meter range. Just know that if your computer doesn't have Bluetooth built-in, you'll need to supply your own adapter.

What makes it interesting is that it's trying to be a complete input hub. It's not just keys; it has a small touchpad with left and right mouse buttons, which is a huge upgrade for navigating a tablet without constantly reaching for the screen. The keys use a scissor-switch mechanism, which promises a decent typing feel for something so thin. It's a niche product, but for that niche, it could be a game-saver.

Performance here isn't about processor speed or frame rates. It's about how well it does its one job: being a portable keyboard. In our database, its overall performance score lands in the 16th percentile compared to other peripherals. That sounds rough, and it is. The main bottleneck is the aging Bluetooth 3.0 standard. It works, but pairing can be slower than with modern Bluetooth 5.0 devices, and you might notice a tiny bit more latency when typing, especially if there's interference.

The real-world implication is that this isn't for competitive gaming or high-speed transcription. It's for writing emails, drafting documents, or browsing the web on your tablet. The typing experience itself is reportedly comfortable for a foldable, which is a win. But the overall performance ranking tells you that in a head-to-head spec battle with modern, non-folding Bluetooth keyboards, this one is going to feel a bit dated and sluggish.

The value proposition is tricky. At a current price of about $102, the Jelly Comb B003B asks for a premium. For that money, you could get a very nice, full-sized, non-folding Bluetooth keyboard with modern tech and better battery life. You're paying almost entirely for the folding form factor and the included touchpad. If those two features are absolute must-haves for your mobile setup, then this keyboard has a place. If you just need a portable keyboard and can live without a touchpad or the fold, your money goes much further elsewhere. It's a specialist tool with a specialist's price tag.

Looking at other portable options, the trade-offs become clear. A standard compact Bluetooth keyboard, like a Logitech K380, will cost half as much, have better battery life, and use Bluetooth Low Energy for easier pairing. But it won't fold, and it has no touchpad. If you need a touchpad, you'd typically have to buy a separate portable mouse.

Within the foldable category itself, there are other models. Some might use newer Bluetooth versions but omit the touchpad. Others might be cheaper but have truly terrible key feel. The Jelly Comb's main advantage is trying to bundle the fold, the keys, and the pointing device into one unit. The compromise is that it doesn't excel at any one thing except portability. It's a jack-of-all-trades, master-of-none in a very specific package.

iPad owners should look elsewhere immediately, as the key feature (the touchpad) is useless to you. Hardcore typists or anyone who needs a primary keyboard for long writing sessions will find the small size and potential latency frustrating. You'd be better served by a high-quality non-folding Bluetooth keyboard. Gamers should also steer clear, as the input lag from Bluetooth 3.0 will be a dealbreaker. If you don't have a specific, compelling need for a keyboard that folds in half, you're paying a premium for a gimmick you won't use. In those cases, a compact, non-folding keyboard offers better performance and value.

If you are a digital nomad who writes on an Android tablet or a Windows 2-in-1, and the idea of carrying a mouse and a keyboard gives you hives, this could be a worthwhile purchase. The fold-and-go convenience and all-in-one design justify the hassle of older Bluetooth for that specific user.

For everyone else, it's a harder sell. iPad users should skip it immediately because the touchpad doesn't work. Anyone who needs responsive typing for gaming or fast-paced work will be frustrated by the latency. And if you only need a keyboard occasionally, a cheaper, non-folding model is a smarter buy. This is a tool for a very specific problem.
