Weikav Stars21 Programmable Numpad vs Lofree EH121: your questions
The Weikav Stars21 is better suited for gaming. Its product specifications list a 1000Hz polling rate for wired and 2.4GHz connections, which can offer lower input latency. It also supports N-Key Rollover to ensure all simultaneous key presses are registered correctly.
Only the Weikav Stars21 offers deep key reprogramming. Its vendor description explicitly states support for QMK and VIA, which are powerful, open-source firmware tools for creating custom layers and macros. The Lofree EH121's description does not mention any similar programmability features.
Yes, according to its vendor description. The Lofree EH121 is described as having two functions in one machine, serving as both a numeric keypad and a calculator. It features a ten-digit display and a one-touch switch to change between the two modes.
The Lofree EH121 has a larger capacity battery at 950mAh compared to the Weikav Stars21's 800mAh. While actual battery life depends on usage patterns like backlighting and connection mode, the larger capacity in the lighter Lofree model suggests a potential advantage for wireless endurance.
Yes, both the Weikav Stars21 and Lofree EH121 are listed with hot-swappable PCBs in their specifications. This allows you to easily change the mechanical switches without soldering, offering flexibility in tuning the typing feel.
The Weikav Stars21 is significantly heavier at 480 grams, due to its CNC aluminum case. The Lofree EH121 is much lighter at 252 grams, utilizing a plastic case construction which contributes to its portability.
Yes, both numpads offer tri-mode connectivity. Each supports a wired USB-C connection, a 2.4GHz wireless connection with a dongle, and Bluetooth, providing flexibility to connect to multiple devices.
Only the Weikav Stars21 features RGB lighting. Its vendor description specifies 16 million RGB colors. The Lofree EH121 has a single-color warm white backlight with adjustable brightness levels, but not full RGB.
The vendor description for the Weikav Stars21 lists 'Diy Kit/Barebones' as an extra feature, suggesting it may not come pre-assembled with switches and keycaps. Buyers should verify what is included in their purchase, as it might require sourcing those components separately.
The Lofree EH121 is more travel-friendly. It is less than half the weight of the Weikav Stars21 (252g vs 480g) and has a slimmer profile in one dimension, making it easier to pack. Its plastic case is also likely more resistant to minor travel scuffs than anodized aluminum.
The Weikav Stars21 uses a CNC aluminum case with surface treatments like anodizing and sandblasting, which typically offers a more premium and durable feel. The Lofree EH121 uses a plastic (PC) case, which keeps it light and cost-effective but may feel less substantial.
