Maybe you should attach the power to a cheap  USB battery pack and leave that permanently recharging?

Some cannot simultaneously charge and discharge.  Some can.

The "USB UPS" is the tool you want here.

I think the bigger problem would be "fluttering" power that might cause the probe to hang and require a manual hard power cycle.

But if the power interruptions are short, an in-line battery should help.

Hello everyone!


I have recently deployed a probe in a place where there's unstable power. Probe is rebooting like 4-5 times a day and unlikely power would be fixed in near future. 


I was wondering if it's safe for probe at all. Does anyone has experience with 4-5 reboots a day with probe? Will probe sustain it or better I just disconnect it and rather wait for power to become stable? 



Curious to hear your experiences. 



Thanks.
