Hi InfiniteDevelopment,
Thanks for your help, yes the PC USB ports are USB 3 and I agree that they might not be supplying enough power but I have the exact same result when using the Pineapple Juice 15000 battery packs I purchased with my new Tetra. I'm not very happy as I intended to use the purchased Pineapple Juice 15000 battery packs for remote deployments with the Tetra but even using both battery packs as prescribed the Tetra still reboots when I enable the PineAP Daemon! The reboot occurs from both power configurations, I've tried using different USB cables and power supplies, PC and Pineapple Juice 15000 I'm starting to suspect the Tetra is a faulty unit.
As I'm in Australia I'll try your suggestion for a charger 12v/2a and repost the results here.
As mentioned I've emailed Hak5 about thi issue but no reply as yet.
Regards.
John
