Overview

The BUODCO HL188 is a tri-fold Bluetooth keyboard that pairs a JIS-standard Japanese layout with an integrated touchpad. It is sold as a standalone input device, but it makes more sense to think of it as a complete mobile typing kit you can carry in one hand. Key pitch is 17mm, close enough to a laptop that touch typists should not need a long adjustment period.
Under the keys sits a pantograph mechanism tuned for quiet operation. That design choice points at cafes, train seats, and late-night living rooms, where the sound of typing carries further than you would like. The layout includes kana legends, which helps anyone who toggles between Japanese and Latin input all day.
Folded up, the HL188 shrinks to roughly phone size and slips into a bag without adding bulk. The leather-textured cover doubles as a stand, so you do not need a separate tablet rest to get a usable viewing angle. At its price point this sits toward the entry end of mobile keyboards, but the combination of a proper JIS layout and a touchpad gives it a clear identity.

Connectivity & Compatibility

Pairing happens over Bluetooth, and the HL188 lists support for iOS, Windows, Android, Mac, and Google. Note that Android 12 is explicitly excluded, so check your device before buying if that is your daily driver.
Up to three devices can be paired at once, and an Fn key combination switches between them. A realistic setup is a desktop at home, a tablet on the road, and a phone in transit, with the keyboard moving between all three.
The touchpad supports left and right clicks, so you can drive a pointer without carrying a mouse. Touchpad input requires iOS 13 or later; older iPhones and iPads cannot use it. If accidental palm contact becomes a problem, Fn plus the spacebar disables the pad entirely.
Charging runs through a Type-C port, and the rated figures are about two hours to full with up to 90 hours of continuous use. An auto-sleep routine stretches standby time past 150 days. The unit is listed as a certified model with Japanese documentation included.

Product Info

At 6,980 yen, the HL188 lands between entry-level and mid-range for folding mobile keyboards. What justifies the position is the bundle of features in one chassis: a JIS layout, a clickable touchpad, a cover that works as a stand, and three-device pairing.
Fourteen function keys cover copy, cut, volume, and similar shortcuts. They occupy their own row, so you press them directly instead of hunting for an Fn chord.
The box contains the keyboard, a charging cable, and a Japanese manual. A six-month warranty is stated for the product.

Best Use Cases

  • Tablet-first workers who write long documents: the JIS layout and 17mm pitch keep typing comfortable, and the cover-stand removes the need for a separate tablet rest. People who only type at a desktop will rarely reach for it.
  • Travellers juggling a laptop and a tablet: three-device pairing lets you hop between both without packing two keyboards. Anyone with a fixed desk setup gains little from the folding design.
  • Quiet-space workers in cafes or shared offices: the pantograph keys and the touchpad kill switch make considerate typing easy. Buyers chasing mechanical key feel should look elsewhere.
