Have a look at the plug you should have something like this (Dyson handheld) printed on it.

Continuing. The important calculation is Power in Watts = Voltage in Volts x Current in Amps. So the output from mine is 26.1V x 0.78A = 20.4 Watts. This should be the power requirement for charging the device. Yours may be similar. The Ocean inverter is good for 150 Watts.

I’m afraid that calculation is not correct. You are calculating the Power Output of the plug at 26.1v.

The Dyson plug requires 240v at 0.6amps so 144 watts.
The Inverter socket is rated at 150 watts. So in theory it should work but is on the borderline.

Thanks @WelshGas. Always happy to be corrected. If the power drawn from the socket is 144 watts and the delivery to the device or power out is 20 Watts, where does the rest go? If the output is 144 Watts at 26.1 V it will deliver over 5 Amps. That seems excessive.

Thinking about it as the charger is multi voltage 100 to 240 volts maybe the 0.6 amps is for a 100v circuit making it 60 watts and a lower current at 240 volts to give the same 60 watts power requirement. In which case it should work fine unless it doesn't like the non-pure sine wave output of the California Inverter.

In which case the current required at 240 volts would be 0.25 amps.

Sorry for resurrecting this old thread but I have a very similar question. Last week I converted our bikes to electric using the Swytch electric bike kit.

The bike charger has an input rating of 100-240V 2.0A Max. I had assumed that the calculation is 240 x 2 = 480 Watts but from what @WelshGas says, maybe the 2.0A Max could be for the 100V circuit making it 200 Watts power requirement, which would be well within the maximum 300 Watts of the T6.1 inverter. If this the case then it would make a big difference to our upcoming 4 week trip to Slovenia and Croatia as we won't need to search around for sites with EHU.

I would really appreciate some advice with this before I'm tempted to try it and blow something up during our trip. Incidentally, our last campervan trip to that part of the world was 50 years ago in 1973 coming home from Istanbul in our 1969 VW Bay-window T2. Happy days!

The quoted output is 84W and for a SMPS, which this must be judging by size, an efficiency of better than 50% can be assumed.

Whether it's design assumptions include modified sine wave remains to be seen. I'd give it a go, listen for abnormal buzzing and check for excessive heating.

You could find a 300w inverter on Ebay (any 12v to 230v inverter I imagine) and ask the seller of this item if it would charge what you want without any damage and get their free advice. I use a plug in inverter to charge my power tool batteries on the go in my work van but not too sure of the wattage

Good idea, thanks! I've put a couple of enquiries out on eBay, will be interesting to see what they say. Interesting that you use a plug-in inverter to charge your batteries - I will look to buy a separate plug-in if the built-in inverter doesn't work.

The newer t6.1 inverter is 300 watts check to see what you have fitted.

Thanks for this info, it sounds encouraging. I'm not sure what the 50% efficiency means but am assuming it's a good thing. I wonder if the sine-wave isn't compatible then could I cause damage?

If I look out for buzzing and overheating and switch it off if there are problems then I guess I can't do much damage. I think I'll give it go!

If the watts is already on the charger then you don’t need to do any calculations AFAIK. 84W is fine. No different to my laptop charger. Ref sine wave I read not long ago that was no longer an issue on the 6.1 300W inverter.

Yes, I do have the 300W inverter but if the calculation is 240V x 2A = 480W then is well over the limit. I must admit, I don't understand this stuff - maybe I should have paid more attention in school physics lessons!

You calculate on the output, not the input. 42x2 = 84 watts, as already written on the case.

It's a high volt item though - expect it to drain your batteries tout suite and get pretty hot.

You'd be better off with a power pack.

Oh right! I assumed it was the input because that is connected to the inverter. This is a game changer, thanks. I have fitted a solar panel from Solar Solutions so that will help with the battery drain.

I don't fancy yet another piece of kit and the power packs seem quite big, so I will see if I can get away with what I already have. Thanks for your help.

TBH the inverter is not designed for the sorts of loads being asked of it, especially people trying to charge large batteries and bikes. It’s meant to be an “emergency” plug if you are not on EHU. It’s basically two lead acid car batteries. Which you need to run the van. A solar panel, or inverter, is not going to give you the longevity you’re looking for to charge up e-bikes off EHU.
