Is there a cordless hand vac that will charge using DC?

I stopped by Wally World to get the specs from the rechargeable I had been considering. The output from the AC plug is 23 volts and 240 MA. There was one other rechargeable there and it's output was 21 volts and 400 MA.

Thanks for the input. It looks like a power inverter would be the best way to go if I want a powerful vacuum when camping off the grid.

I use a 2 gallon wet dry vacuum powered by the 2000 watt inverter.
Cleaning power is somewhat better than those rechargeable toys.

Otherwise I recommend a small sine wave inverter to recharge.
Probably find it handy charging other items also.

I just went through this and all the "good" rechargable , hand-held vacumes I could find charged at 15-18 volts.

I bought one of these and it is truly amazing! Made in America by a small father and son team. Not DC, but small and EXTREMELY powerful.

The battery voltage on the more powerful ones may be much higher than a normal lead acid battery.

Just buy a small inverter to run the charger and unplug it when it is fully charged. You can get a small inverter with a lighter plug that should handle the current. Check the wattage on the charger of the vacuum and find a suitable one at an automotive store.

Might want to consider a small plug in type inverter in the 50 to 75watt range
Used one of them for many years with no issues charging our cordless Dyson Vac

Almost all of them will charge on DC just have to cut off the wall wart and put on a dc plug like a cigar lighter plug and plug it in.

Well, if the wall wart has a 12 volt output that might work. If the wall wart is 6 or 9 volts though you'd likely end up letting the magic smoke out of it.

I understand the desire for cordless, who can't, but screw that,

I'm getting one of these, just add 5 or 3 gallon bucket:

4 amps at 115Vac AC. Hello inverter.

Lowes sells a bucket top version for the same price but it is SHop Vac branded and consumes 6.5 amps.

From what I have seen, the batteries are the first to fail.

Just a suggestion and only if you are keeping this RV for awhile.

Install a 12V whole house vacuum. The one in my Allegro mounts in the basement and has a suction line up to the house. There, a wall plate serves as the receiver for a long hose that will reach the whole RV. It does a decent job and runs off of the RV battery.
