Mini UPS query

[wingnut771]

this is a other calculation I found

Charging Time = Battery Capacity ( Ah ) (Divided by) Charging (input) Current to Battery (A)
Time= 16.80/1 = 16.80 Hour.
If its 2 A
then Time =16.80/2 = 8.40 Hour

I think this is ignoring voltage and assume both are the same.

 

[AlphaJohn]

12v x 1.5A = 18W times 0.8 for losses (14.4W)

Your capacity is 38.48Wh

38.48 divide 14.4 = 2.67 hours

In theory.

Erm W vs Wh they not the same

14.4W times 2.67 hours = 38.48Wh

14.4W times 2.67 hours = 38.48Wh

I have one of these bad boys branded as Andowl. It has a single power output with a cable split to two plugs, so one setting for multiple devices. I have been running my ONT (12V) and Router (9V) at 9V successfully for about two years now. I have had them run on battery for up to about 6 hours. Would definitely recommend.

I edited my post a little. There could be more losses, what is the level at now?

4 lights first two lights is now stable, with the last two blinking. Indicating more than 50% but less than 75%.

Okay, then I think a good estimate would be to say it will take half the time to charge, so 4.5 hours, we don't know the internal circuitry/charger inside. Please let us know the final outcome, as my UPS just sits on 100% because we don't get loadshitting here in durban.

I was using the genny, had to stop to fill up. But it was fully charge by 12. Including the 1 hour offline. So 4.5 -5 hours feels right.

Yeah, I think it only uses half the power out the power supply so 0.75A.

So both my routers are 12V1A, but the Gizzu outputs are 9V3A, 12V3A, and 12V5A. Does the difference in A matter? Can I safely use this UPS on these routers?

Yes you can.

 

[Eonv]

Yes you can.

Thank you!

Sorry to hijack this thread.

Anyone know of 24V mini UPS options out there? My router and ONT have different power requirements, 12V 1A and 24V 0.8A (combined drawing 31W).

Any advice is appreciated.

Thanks

Gizzu has one that can do that but I’m not sure one exists that can do both at the same time.

This is my one, running like a peach Nic Cage could eat.

My old man & my buddy bought the same one after my recommdation & they are both happy.
