How can I plug in an AC device without a wall plug or car?

Question

I need to bring my portable DVD player for some marketing events for my job. But most of them are outdoors and I don't have access to my car adapter or any outlets. I bought a portable lithium battery pack but it only has a USB input/output and my DVD player doesn't have a USB power output. I'm not allowed to bring a generator with me. Is there another portable power option that isn't loud and bulky? Or an adapter to plug the AC wall plug into that can then be plugged into the USB charger?

I really need help. I've looked everywhere and any adapters are either $300 or more, a loud generator or need a car to plug into. I have another event coming up and the client has specifically requested I bring a video of their products with me.

Thanks!

Answer 1

USB can't transfer power, they can only transfer data. Ever wonder why we don't have USB powered laptops?



You would need to either get a bigger battery or just charge it more often.



Best of luck.

Answer 2

A USB port does provide 5 volts DC power (besides the data transfer; its main purpose). It can be used for just the power connections on it, which is what your battery pack does.



It's a shame you can't use your car adapter!



You might be able to use a car battery. You'll also need a car battery charger, and a cable with a "cigarette lighter" socket on one end and red+black alligator clips on the other. Though it wouldn't be much less bulky than a small generator, it would be completely silent, and should run a portable DVD player for hours. You mean the portable DVD players with a small flip-up LCD screen, right?



If you want 120VAC instead, you could use a car battery and an AC inverter, or an UPS.



I am reminded of the scenes in Ironman, where Tony Stark is lugging around a car battery before he invents his arc reactor.

Other answers came in while I was writing... That Duracell Powerpack 600 looks like it'll work for you (they say it can actually power devices, specifically mentioning power tools -- the Energizer Portable Outlet info only says it "provides charging power" and it doesn't cost any less, so I'd get the Duracell PP600 over the EPO).

Answer 3

A totable battery pack will do.



The Duracell one is an excellent choice (the same units are sold at Canadian Tire in Canada, under their store name). You can use the car adapter, or AC supply fine. It will have plenty of capacity for several hours. They sell for around $150.

Answer 4

Google "Energizer Portable Outlet"



See if that gadget will do the job.
