Using Power Stations to power COB lights?

A

analogs

Well-known member
I am considering buying a power station to run an Aputure 120D II light instead of a V-mount battery?

Any advise regarding this route?

How do I know which power station to buy?
- pure sine wave
- 150 Wh
- AC output 100 Watts continuous

Does it matter if I use a power station that only outputs 110 AC when it is plugged in Australia that uses 240volts? Will this cause issues with flickering, sync issues with lighting with other lights?

If its AC output is 100 watts continuous, what would happen if I put the 120D on full power as it uses 120 watts, will that damage anything or just shut off?

Does anyone know which lasts longer or has grater recharge cycles, V-mount batteries or Power Stations?

Here is an example of the options - https://www.ebay.com.au/itm/S270-S1...hash=item41f4eca7fc:m:m8p153sTU4dsA6iwE1G1Czg
This only outputs 110 volts AC.

Thank you.

I'm not seeing any advantage to using the power station. It is a battery and an inverter. So now you have more things to fail than just a battery. Plus you have double conversions. Battery to AC in the station and then AC to DC in the Aputure. That's a waste of power.

Most everything is 90-240V input these days, so I'm assuming the Aputure is the same and it is not an issue. Check the specs on the Aputure input. No, it won't add to any flickering issues that may already be there.

Screwing up is trying something that won't work just in case it will. If it says it will only output 100W and you want to draw 120W, well, your guess is as good as anyone's on what will happen, but it won't be good. It says it has thermal and short circuit protection, so maybe it will protect itself from being destroyed, but who knows.

It's bigger than a V-mount. I'm no fan of V-mounts, but I'm not seeing much on the plus side here. But maybe you have some other reasons to use it.
 
Thank you for the reply Paul.

I thought these would last longer than using V-Mount batteries as they seem to have better value when comparing price to how long they will run a light for.
 
V locks do not provide the best WattHours/$.

What you want to do is used the DC input if the light has one.

If you need 24v in then get a 24v DC battery of some nature.

THere are doubtless many options cheaper (bulkier and more ugly) than Vlocks.

Learn what a Watt/Hour is, max current draw is and the like and then buy a bettary.

Basics
W=VxAmps
Watt Hour = abilitiy to deliver X watts for an hour until the battery is charged.

Just because a battery has a lot of watt hours that does not mean it can deliver them all in one hour.. that is limited by the max current (amps) the batter can deliver.

FYI my 12v panels I run them off caravan leasure batteries, which are huge, heavy and super cheap. (cheap fast and good doesnt exist!)
