Powering Mikrotik hAP ax² Router from Power Bank

RouterOS General
1

Hi everyone,

I’m having trouble powering my Mikrotik hAP ax² router via a USB To DC 12V Step Up Cable from a power bank. The router specs say it can consume up to 27W, but in my setup, it’s around 11W.

The issue: The router goes into a boot loop when I try to start it from the power bank. I’ve tested three different cables, and it seems the current might be less than 1A, or the router needs more power during startup.

Any suggestions or experiences with this?

Thanks for any help!

UPD: I have resolved this issue using the Type-C to DC cable and a 65W power bank (both supporting PD). Thank you for your assistance!

Ordinary USB to 12V adapters are probably a bit limited.

However if it is a PD or a QC3 powerbank.
You can get PD or QC3 USB to DC connector, with a trigger circuit for QC3 or PD (different cables)
So 12V (or 20V) is provided direct from the power bank.

Read the Chinese advertising information correctly. USB 1A 12V means 5*1=5W

No, there are plenty of USB powerbanks that support different voltages. Just need the proper adapter

Or use ax lite.
Matches beautifully with most power banks without need for any convertor.

Test your boost adapter and see how much power it actually provides, and if the voltage is consistent with different power draws.. At the very least, sometimes the posts specs are just ‘wishful thinking’. And yes, the boot cycle may have more draw than running, I can’t confirm for that device though.

Suggestion, use a 12v power bank.
