Ajazz AK820 Max Plus vs AK870Compact Battery vs Gasket Sound

The Ajazz AK820 Max Plus has a significantly larger 8000mAh battery, double the 4000mAh capacity of the AK870. This makes the AK820 Max Plus the better choice for users who want to minimize how often they need to charge their wireless keyboard.

The Ajazz AK870 uses a gasket mount, where the plate is suspended by silicone or rubber gaskets to dampen sound and provide a softer typing feel. The AK820 Max Plus does not specify a gasket mount in its description. Gasket mounts are often preferred for a more premium and customizable acoustic experience.

Yes, both the Ajazz AK820 Max Plus and the AK870 feature hot-swappable PCBs. This allows you to easily remove and replace the mechanical switches without soldering, using the included switch puller tool.

The Ajazz AK820 Max Plus is more portable. It is lighter (850g vs 970g), shorter in length (333mm vs 370mm), and uses a more compact 75% layout that omits the function row and numpad found on a full TKL like the AK870.

Both keyboards have RGB lighting. The AK870's specification confirms south-facing RGB. A user review for the AK820 Max Plus also mentions south-facing RGB lights, indicating both models feature this design for better compatibility with shine-through keycaps.

According to their listings, both include a keyboard, USB-C cable, 2.4G receiver, keycap/switch puller, and manual. The AK820 Max Plus also lists a dust-proof cover, which is not mentioned for the AK870.

The Ajazz AK820 Max Plus has a 0.85-inch TFT screen. The Ajazz AK870, in models equipped with a display, features a slightly larger 1.06-inch TFT screen according to its vendor description.

The TKL layout of the AK870 is often preferred for programming because it retains the dedicated function (F1-F12) and arrow keys without the bulk of a full-size keyboard. The 75% AK820 Max Plus combines the function row with the number row, which some programmers may find less intuitive for frequent function key use.

Yes, both the Ajazz AK820 Max Plus and AK870 list support for Mac and Windows operating systems in their specifications. The AK870 vendor description also mentions compatibility with iOS and Android.

The AK870 is designed for a quieter sound, according to its vendor page, which details a 5-layer filling gasket structure and slotted PC plate to reduce noise. The AK820 Max Plus uses a layer of silicone and cotton for sound dampening, but lacks the gasket mount system, which may result in a different acoustic profile.

Yes, the vendor description for the Ajazz AK870 states that the screen module "can be changed into 3 keys," offering flexibility if you prefer additional physical keys over the display.
