“I realy like this keyboard. I feel is harder to make typos compared to the K3 v2. I decided to go with the K1 Pro instead of the K3 Pro and it's going to to take time to adjust to the new layout, but the feeling and shape of the keys is definitely better.”

“For anyone buying this, remember to toggle the switch to the correct operating system. Other than that, the feel is good and it comes with a good feature set for a low price”
“I was happy at the beginning but after few months of use I'm getting more and more frustrated. Keyboard just hangs sometimes and I'm not able to connect with BT. I use it to operate two laptops and using Fn+1 anf Fn+2 combination is great... when it works…”

Keychron K1 Pro vs K3 Pro: your questions
The primary difference is the layout size. The K1 Pro uses an 80% tenkeyless (TKL) layout, while the K3 Pro uses a more compact 75% layout. Additionally, the K3 Pro includes 2.4 GHz wireless connectivity, which the K1 Pro lacks.
The Keychron K1 Pro has a larger 2000mAh battery, while the K3 Pro has a 1550mAh battery. Based on the specifications, the K1 Pro should offer longer use between charges, assuming similar usage patterns and lighting settings.
Both keyboards offer a hot-swappable version as an option. However, according to the manufacturer, both are currently compatible only with Gateron low-profile mechanical switches and do not support low-profile optical switches.

Yes, the K3 Pro is significantly heavier. It weighs 930 grams, while the K1 Pro weighs 580 grams. This is notable given the K3 Pro's more compact dimensions.
The K3 Pro is more compact in size (306mm wide vs. 346mm), making it easier to fit in a bag. However, it is heavier. The K1 Pro is lighter but has a larger footprint. Portability depends on whether you prioritize smaller dimensions or lighter weight.

Typing preference is subjective and depends on layout familiarity. The K1 Pro offers a standard TKL spacing which many typists prefer. The K3 Pro uses a condensed 75% layout. Both share the same low-profile Gateron switches, PBT keycaps, and redesigned stabilizers, providing a similar core typing feel.
