Anyone compare CAT Power Stations/Battery Jumpers from Costco?

I’ve have this CAT #CJ1000DXT Power Station for the past few years and it’s been great, but definitely bulky and heavy. I wonder how it compares in performance to the newer CAT Lithium Power Station #PPSCL3 from Costco. Physically it is tiny and very lightweight in comparison.

The reviews are not very encouraging. Nice try, a real need, but needs refinement. Lithium can't do everything.

No internal power supply or AC cord, a USB cable takes 8 hours.

Out of curiosity, since there is never a meaningful spec for the inverters of these types, could you measure a 100 watt light bulb in minutes or hours? On a fully charged battery? Yes 200 watts is the spec but for how long?

Looks like a good value for what you get, but IDK how good it actually is.

One poster on the following Reddit thread claims the sticker on the side of the lithium version shows a capacity of 3.7 amp hours at 11.1V, which works out to 41 watt hours.



As for the one you have already, a separate thread claims it has a 12V, 19 amp hour battery, which works out to 228 amp hours. Given that it's lead acid, discharging below 50% isn't ideal for battery longevity - so you get about 114 usable amp hours.



All of that to say, the one you have - if it still has the capacity it did new - gives you about triple the energy storage vs. the lithium version. So, the lithium wins for portability, and its claimed peak output is higher when used as a jump starter. The older one should let you supply power to devices for about three times as long.

I received a DeWalt DXAEJ14 power station as a Christmas gift from my FIL. It's been a great portable charger and air compressor, highly recommended. It holds a charge for several months even without use and can still jump start a 12V battery (granted, on a mower) as well as air up several tires.

Just re-read my post and realized I messed up the units in the portion quoted here.

Thank you for this information!

I actually haven’t even got to charge it in over a year since I lost the charging cable. I’d buy one from Amazon, but I keep thinking I will run into it when I’m digging thru all my junk lol! I was still able to jumpstart a few cars with low batteries just a month ago.
