Battery powered pressure washer

[Jerrysends]

Looking at getting a battery powered pressure washer for detailing my vehicles (homeowner use) after one of my electric ones died. Trying to save setup time over the large electric washers. Does anyone have feedback on these two products powered by Dewalt batteries?

Would I be better off with an electric model?

Slenjafin 700psi pressure washer powered by 20v Dewalt batteries. $65 from Amazon, a 4.5 rating

Dewalt 20v 550psi DCPW550B battery powered pressure washer. $129, a 3.8 rating on Amazon

Those are so wimpy and still need a hose (or bucket with siphon)
Get a small electric model.. use with one of those expandi hoses for faucet hook up.
ryobi's as low as 59.99

The 69.99 model has 2-5x the cleaning power of the best battery model.

GPM is generally where you'll be wishing for more performance when washing a car. Unless you're cleaning bare metal, you won't want to hit your vehicle with high pressure anyhow. The 1.0 GPM of the unit listed in the OP will take a painfully long time to rinse soap off of a car.
