Charge or use a T:slim X2 with an external cell phone USB battery pack

Has anyone tried to charge or use a T:slim X2 with an external USB battery? I’m going on an extended backpacking trip this summer and would like to use one as an emergency back-up. I spoke with Tandem technical service last night and they said it will work, but I’m still a bit skeptical and would like to hear from someone who has successfully done it.

Dexcom / Tandem - No difference.
