ChargeTech Plug is the 48,000mAh power bank you can probably run your house on for a tiny bit

Power banks are some of the most useful tools for electronics users on the go, but at best, the more popular and portable ones are good for a charge or two of one gadget before they die off. That's why ChargeTech made the power bank to end all power banks – a 48,000mAh capacity monolith that can let you take almost all your essential electronics for a day out, and is still somewhat reasonably sized and portable.

Priced $330, the bank is fit with two AC outlets, two traditional USB ports, and a USB Type-C port. It's solar-rechargeable with the optional solar charging panel, and takes around 8 hours to recharge to full, which is still reasonable considering how much power gets stored. The thing uses 16 x 3,000mAh Panasonic battery cells, the same used in Tesla cars. Despite that electrical excess, Plug measures 8.6 x 1.6 x 5.6 inches and weighs around 2lb, so you can actually carry it in most of the bags you probably own and not break your back.

Plug is about to start shipping to its backers and can be ordered from its Indiegogo page. It will eventually make it to regular retailers, priced at $350. In addition to charging gadgets, it seems like a convenient source of electricity for camping trips and other occasions where you are outside and need some electrons in your life.

This thing doesn't even have enough juice to charge my laptop....

That's impossible. The maximum battery capacity for a laptop is 99Wh. Anything over and you can't carry it in certain places like planes. 99Wh translates to 26750 mAh. This thing can charge it almost twice. And most laptops have batteries much smaller, around 50-60 Wh. So they can be charged 3-4 times easily.

That math seems off? I might be wrong though bit 99 wh should be significantly less depending on voltage you are calculating with?

3.7 V is the standard voltage for a phone and that's what the power bank mah ratings are based on, since phone batteries are either 3.7 or 3.8V. 99/3.7 = 26.75 Ah = 26750 mAh. The math seems fine.

Ah, yeah, I was going by 12/21V for laptop batteries since that was what we were talking about :)

That would have been wrong since you can't compare mAh at 12V to mAh on 3.7V.

Obviously not :) Though was thinking capacity wise looking at wh vs mah, a phone battery wouldn't run a laptop either, couldn't handle the output, but yeah :)

That also said, this thing really is a beast there are many UPS out there with less power then this guy.

This article is missing the "sponsored" label. How can a fridge run off this? Maybe a frigobar but not an actual one, doesn't even show amperage.

they said it use 16 x 3,000mAh Panasonic battery cells totally sure they use 18650 battery which is 3.7v convert that capacity to Wh, and you'll get 177.6Wh you can run 250watt fridge for around 40minutes (still useless though, it can barely cool anything at 40 minutes :-/)

Most fridges are around 100 watts though so if its 40 minutes for 250watts then it can cool the fridge a bit in 100 minutes
