Ajazz AK820 Pro vs Redragon EISA K686 Pro: your questions
The Ajazz AK820 Pro is better for small desks. Its 75% layout measures 327 x 136 mm, which is significantly more compact than the Redragon EISA K686 Pro's 430 x 90 mm 96% layout. This frees up considerable space for your mouse and other peripherals.
No, the Redragon EISA K686 Pro does not have a screen. The Ajazz AK820 Pro features a 0.85-inch TFT screen that can display battery status, time, and connectivity information, which is a unique differentiating feature.
Yes, both keyboards are hot-swappable. The Ajazz AK820 Pro supports 3-pin and 5-pin mechanical switches, and the Redragon EISA K686 Pro vendor states its socket is compatible with nearly all 3-pin and 5-pin switches.
Only the Ajazz AK820 Pro has a specified battery capacity of 4000mAh. The Redragon EISA K686 Pro product listing does not provide a battery capacity, so a direct comparison on battery life cannot be made from the available information.
Both keyboards are designed for a comfortable typing experience. They use gasket mount designs to reduce noise and vibration. The Redragon specifically mentions sound-absorbing pads and foams, while the Ajazz uses a flex-cut polycarbonate plate and PCB for a cushioned feel.
Yes, both the Ajazz AK820 Pro and the Redragon EISA K686 Pro list Mac compatibility as a feature. The Ajazz vendor notes a side button for switching between Windows and Mac modes.
The main difference is size and key count. The Ajazz AK820 Pro is a 75% layout with 81 keys, omitting the numpad and some function keys. The Redragon EISA K686 Pro is a 96% (or 90%) layout with 98 keys, keeping the numpad and navigation cluster in a condensed form.
The Redragon EISA K686 Pro is heavier, weighing 1060g (1.06 kg). The Ajazz AK820 Pro weighs 810g (0.8 kg), making it notably lighter and more portable.
Yes, both include accessories. The Ajazz comes with three extra keycaps, a 2-in-1 puller, a cable, and a receiver. The Redragon includes a keycap and switch puller, four spare switches, a cable, a receiver, and a sticker.
Both keyboards feature south-facing RGB LEDs. The Ajazz AK820 Pro vendor specifies 1.6 million color combinations. South-facing LEDs are often preferred as they provide better shine-through for keycaps and avoid interference with certain switch types.
Information is incomplete for a full comparison. The Ajazz AK820 Pro listing confirms a 1k Hz polling rate in its 2.4GHz wireless mode. The polling rate for the Redragon EISA K686 Pro in its 2.4GHz mode is not specified in the provided details.
