Heltec v3 power requirements

Support
1

Hi, sorry for the noob question, however could really do with the support I am currently running a heltec V3 over a 1 m USB cable plugged into an Amazon 5 volt 1 amp wall charger.

To gain further elevation, I plan to plug in downstairs and run a larger USB lead of around 5 m up into the loft.

Question is what is the recommended power requirements to make this setup work effectively please?

I have the option of a one amp. 5. Volt plug or a 2 amp. 5. Volt wall plug,
I currently have no facility to hardwire in the loft and there is going to be no batteries.
please advise?

Cheers

you can expect the heltec to use 40-100mA , so the power supply wont be the problem. even a 500mA would be more than needed.
i would expect a 5m usb cable to be good for this little current.
if the cable is too long, there can be a small voltage drop. but the heltec will run on much lower voltages than 5V. so, NO PROBLEM
