Back2thefuture Posted July 10, 2018 Share Posted July 10, 2018 Can someone recommend a battery pack that they’ve had extensive field testing with? I purchased “Portable Charger RAVPower 26800 Battery Packs 26800mAh Total 5.5A Output 3-Port Power Bank” and it does not seem to be as advertised...during heavy consumption my Tetra just crashes and reboots Link to comment Share on other sites More sharing options...
b0N3z Posted July 10, 2018 Share Posted July 10, 2018 i use 2x anker 10000mah batteries. Im pretty sure the tactical kit comes with anker 13000mah battery. you need a total of 5v4.8a to power the tetra which is 2x 5v2.4a ports. Ive had a lot of luck with anker. the ravpower 20000mah battery I got is the same way as you have described. Also use 2 separate cords. Ive found that using a y-cable is shotty with the tetra. So plug one into eth1 and the other into the uart micro usb port. I have also made my own y-cable from really nice cables that way fitment for the port is tight. Y-cable <-- I grabbed 2 of these Micro usb cables and one of these. Link to comment Share on other sites More sharing options...
Dave-ee Jones Posted July 10, 2018 Share Posted July 10, 2018 So dodgy powering the TETRA by combining different power sources..It might seem like a good idea for field work but at the same time..nah. Link to comment Share on other sites More sharing options...

I just tried using two separate micro USB cables with the same battery and it might just be the Hak5 USB Y-cable. The battery I bought should technically be enough...I did look for quite a while before buying it> RAVPower 26800 Battery Link to comment Share on other sites More sharing options...
b0N3z Posted July 11, 2018 Share Posted July 11, 2018 its a good battery but the y-cable is definitly a loose in the port. I also make sure my Tetra is quite secure in whatever I need to carry it in, that way the cables aren't moving around and causing reboots Link to comment Share on other sites More sharing options...

merlin20302 Posted August 30, 2018 Share Posted August 30, 2018 How Long can You use the Tetra with one Anker (10000mAh)? Link to comment Share on other sites More sharing options...

Tetra = 18W max load so worst case calc would be 18W / 5V = 3.6A 10Ah / 3.6A = 2.7 Hrs 2.7 hours * 60 = 162mins But that is continuous max load so will be much better than that if idling or doing low power tasks.

Ethermine Posted November 17, 2018 Share Posted November 17, 2018 XTPower XT20000QC2 This is the battery I use and it has been great. Charges quickly with a dc adapter, can output from dc port so you can connect this to your pineapple without wasting your other ports to power. Reasonably small, you can put it in a backpack anywhere and thread it to your device. I went through a lot of batteries until I found this one. Give it a shot.
