Can Omars powerbank of 100-230V, 90-120W support a 100-240V 0.3-0.5A appliance
I have an electrical appliance (it's a CPAP machine) that's labelled its input power as:
100-240V, 0.3-0.5A, 50-60Hz
Can the Omars 40200mAh powerbank below support (ie power) the above CPAP?
https://www.ebay.com.sg/itm/283550204371?ul_noapp=true
From youtube url below, appears that Omars powerbank's AC output gives
110-230V, with amperage unspecified:

Does the powerbank auto-adjust its amperage output??
Just don't want to burn / cause over-current to the CPAP machine as this
voids the warranty

What voltage is used in your country?
Stupid question, why not just get a power bank from the manufacturers and not worry about voiding your warranty in the first place?

The power bank will not supply more current than the device draws. My question is why don't you just plug the CPAP machine into the wall. Does it use a USB cable for power? Are you planning on flying and want to use the CPAP machine while in air?

> Can't you get one from China where it's probably made?
I've been hunting for one such DC to AC inverter in Asia but none found.
>The power bank will not supply more current than the device draws.
The current required by the CPAP is only 0.3-0.5Amp. As for voltage,
the CPAP (a Spanish brand) can accept anything 100-240Volt.
Yes I'm travelling outdoor with the CPAP.
i know of cpap.com that sells powerbank that cost US$320 & you'll still
need to get a US$69 inverter to be able to support the CPAP model I have.
I reckon this Apex XT CPAP was imported by a local dealer here from USA.
>That gives you a max current of 0.75 Amps, more than the 0.3 to 0.5 of the CPAP.
Think the above answers my question.
Can I safely say it's the voltage that will burn/trip an appliance & not the amperage?
>But 42,000 mAH at 5 volts is only 210 Watt-Hours... for 4 to 6 hours of operation
I plan to get 2pcs of the Omars powerbank so that will give me at least 8 hours
tho I'll need to wake up in the night to switch over

The manufacturer doesn't make one. Well, I could have got the Resmed CPAP as Resmed does make
a powerbank for it but Resmed is rare in my country & costs easily double of the Apex CPAP.
from cpap.com, it sells 3rd party powerbanks for the different CPAP that they carry but you'll need
to get their 150W sine wave DC-AC inverter.
My biggest concern is: will Omars 40200mAh powerbank damage (over-current/trip) the Apex XT
CPAP. This CPAP costs me about US$850 so can't afford to get another one. If the powerbank
fails to power the CPAP, doesn't matter as I can use the powerbank for other purpose & I'll
skip using powerbank when I'm going outdoor. My apnea condition is quite serious that even
with 9-10 hours of uninterrupted sleep, I can still doze off while driving. This CPAP makes a big
difference to my 'awakeness'

The powerbank outputs DC, which if you go through an inverter you will have a loss as it takes energy to convert from DC to AC. What you could use is a small UPS instead that already has the inverter built in and will be more efficient than the powerbank/inverter scenario you propose .
What I'd be doing if it was me was see if the unit uses 12V internally and if it doesn't need line power but uses low voltage DC internally I'd wire in a jack

Have you reported this "doze off whilst driving" condition to the driver licensing authority?

It's recorded in the public hospital; in the doctor's report. The doctor shared a number of
taxi / cab drivers have this issue.

In the youtube link I've given above (ie https://www.youtube.com/watch?v=b4QE44yEstI ) ,
it shows this Omars powerbank has an AC output port : reckon it has an inverter built-in
