Something that has an internal battery. I can plug into 110v to charge it. has a 12v receptacle that I can plug a 12v device in and will allow for hours of 12vdc if service. Seems like I saw a duracell unit but cannot seem to find. Any help? Thanks

Portable power station?

Car battery and AC charger?

It sounds like you're describing one of those power packs for jumping a car.

2000 Peak Amps
700 Cranking Amps
High Output for Industrial Applications
Long 46" #2AWG Cables
Industrial-grade Hot Jaw Clamps Penetrate Battery Corrosion
12 Volt DC Outlet to Power Accessories
Automatic Built-in Charger

What exactly are you trying to plug in? if its usb then there are thousands of options. just do a quick search. If you actually need 12v then again do a quick search on 12v powerpack and you will see hundreds of options. Unless you have some reason for a fully packaged solution I have built quite a number of these and its easy.

Easily portable or pretty much stationary?

Thanks guys, yes you have nailed to a degree. The pump for my portable shower has a male 12vdc plug that runs the pump. Something like the Jackery seems like a well made unit. The 240 would be awesome but $200 is outside my budget. The 160 explorer would work. It does not have the built in 12v receptacle. But does have a plug adapter that provides the receptacle for $100

Consider This

Has USB charging port and a 12 Volt cigarette lighter type plug in and right at $100 might be budget friendly. I think it provides power longer than the Jackery
.

Check out the Schumacher Jump Box.

Nice little unit which has some nice features.
Set air pressure and it automatically stops when reaching the desired digital setting.

Thanks guys, that does look like a good unit.

yep, sounds like you need the basic booster battery as pictured above to me....

to comment... I don't see how a usb plug could handle the amps of even a small pump.... need 12 volts and I presume the pump would have the correct size wire.

Oh, and the nice thing about these booster batteries is you can actually charge them faster by just connecting to the batter in a vehicle while it is running....
