Ajazz AK820 Pro vs Yunzii AL6675% Screen vs 65% Aluminum

Only the Ajazz AK820 Pro has a screen. It features a 0.85-inch TFT screen that can display battery status, date and time, connectivity mode, and operating system, according to the manufacturer's description.

Yes. The Yunzii AL66 features a CNC machined aluminum case for both the top and bottom, as listed in its characteristics. The Ajazz AK820 Pro uses an aluminum case with an ABS plastic top.

The Ajazz AK820 Pro is likely better for an office. Its 75% layout includes a dedicated function row and navigation keys, which are useful for spreadsheet shortcuts and document editing without memorizing layers. Its linear switches may also be quieter than the Yunzii's default clicky switches.

Yes, both keyboards are hot-swappable. The Ajazz AK820 Pro supports 3-pin and 5-pin mechanical switches. The Yunzii AL66 also has hotswap sockets that support both 3-pin and 5-pin switches, allowing for easy switch replacement without soldering.

The Yunzii AL66 includes more detailed sound-dampening materials. Its vendor listing specifies it comes with Poron sandwich foam, Poron socket foam, and PET sound pads for sound absorption. The Ajazz AK820 Pro mentions sound dampening and a gasket mount but does not detail specific foam layers.

The Yunzii AL66 has a larger battery capacity at 4600mAh, while the Ajazz AK820 Pro has a 4000mAh battery. This suggests the Yunzii may last longer on a single charge, though actual battery life depends on usage patterns like RGB brightness and wireless mode.

Yes, both keyboards are compatible with Mac and Windows operating systems. The Ajazz AK820 Pro listing explicitly states Mac/Win compatibility, and the Yunzii AL66 characteristics list both Windows and Mac compatibility as 'Yes'.

The Yunzii AL66 is more compact due to its 65% layout, but it is much heavier at 1145g. The Ajazz AK820 Pro is a 75% layout and lighter at 810g. For pure size, the Yunzii wins, but for a balance of size and weight, the Ajazz may be easier to carry.

The Ajazz AK820 Pro is a 75% layout, which keeps the function row, arrow keys, and a column of navigation keys like Insert and Delete. The Yunzii AL66 is a 65% layout, which removes the function row and further condenses the navigation cluster, requiring the use of function layers to access those keys.

Yes, both keyboards feature a metal control knob. According to their listings, the knob on both can control volume. The Yunzii AL66's description also notes the knob can control RGB modes and brightness.

The Ajazz AK820 Pro is likely quieter by default. It comes with linear switches and uses a gasket mount with sound dampening to reduce noise. The Yunzii AL66 comes with clicky switches, which are inherently louder, though its extensive foam kit would dampen other case noises.
