Does anyone have an advice for an external battery pack or power bank to connect to the Karoo 1. I am facing battery life time issues like many others, and since replacement isn't offered this might a way to extend the use of my Karoo 1.

Are there any technical specifications I need to take into consideration when connecting a battery pack or power bank, such as:

• min./max. storage capacity in mAh (Milliamp Hours)
• min./max. charging capacity in A (Amperage)
• min./max. V (Voltage)
• any other technical specification ?

  If you are planning on using the powerbank to charge the Karoo while riding, I’d say pretty much any USB powerbank will do and the main considerations are mechanical: general robustness (powerbanks handed out as swag are just awful), form factor (do you have a frame bag where it fits or will you just attach it to the handlebar), and finding a cable that isn’t too long and fits between the unit and the handlebar, if you are using an out-front mount.

  (I personally have used some small thing from Anker about the size of two fingers attached to the handlebar near the stem with a couple of elastic bands.)

  Using the Karoo standard mount, will there be enough room between Karoo2 and steer/stem to get the USB-C in without stressing it?

  Depends on the size of the USB-C plug on your cable. I have a couple of random cables with a small enough plug that it will fit comfortably enough, but most cables (iirc including the one that came with the unit) definitely won’t.

  I use a USB-C cable with a 90 degree connector for this purpose, otherwise the connector won't fit between the Karoo and my handlebars.
