For baro-probe to XCtrack usecase - We recommend only high quality cables - you can now get one as bundle with vario

Vario has non-rechargeable battery. Charging via USB won't help.

CR2032 battery for 20 cents will power your vario for another 200h. You can buy it on every gas station or supermarket. No worries to connect vario to USB, battery won't be connected to power. Why vario uses one time battery? Because it is effective for devices, what lasts a year or more. Like TV remote, like car remote.

SkyBean2 learned and improved all good skills from its older brother SkyBean vario. This compact audio vario is durable and reliable flight assistant. Instead of breathtaking feature list, there are some practical use cases, where for sure you will find yourself:

• Beginner pilot should focus her/his attention to basic pre-flight preparation, not to set up complex flight computer. Also during flight, she/he must concentrate to all those new feelings and not to study actual glide ratio on half bar.
• Commercial tandem pilot doesn’t have space for large instruments, neither a need for obvious info in her/his well known playground.
• SkyBean2 can quietly stay for years resting in harness pocket and with pleasure will do its job, when you will forget your main vario at home.
• Everybody now has a smartphone. Those with Android can turn their phone to full featured flight computer when connecting SkyBean2 as a baro probe to XCTrack app. Suddenly, they don’t have to carry another heavy brick over the mountains.
• Are you tired of super flashing technology all around which requires so much attention to keep it alive? Is flying just your pure natural relax? SkyBean2 can serve as a little undemanding assistant, which will work for hundreds hours without energy feeding.
• Some pilots like to experiment and try to set every single variable in their world. However SkyBean2 is just a simple audio vario, it offers a plenty individual advanced settings, adjustable through friendly PC interface.
• Solar panel? NO. Why not? Not needed. If vario last for 150h, you don't need solar panel. If you don't trust this explanation - Answer yourself - Does your car key have solar panel?
