Did they?


Even if they did, it would be an incredibly stupid thing to claim about a USB adapter.


This thing looks so flimsy, it’s just gonna break. And it normally retails for 80 bucks? lol

Unless I can cut someone with it, it’s not much of a swiss army knife.


I like how the lightning and USB-C connections are just loose adapters, so prepare to carry around an extra-tiny thing with your very loseable and fragile tiny thing.


Not Forbes magazine.

Billy Forbes, the plastic magnate.


I’m beginning to wonder if StackSocial Ad copy is being written by a Trump campaign almum. It seems to have a similar relationship with the facts as the Trump campaign… :-/


Time to dump on this product.

1:52 “You won’t even notice it…”

missing from your backpack

1:55 “Until you need it”

And at :13 , they couldn’t even place the device to be in focus.

Also, 9v ? There’s no juice in a 9v battery, a single AA packs way more punch.

Plastic magnates - how do they fucking work?

Wait? Forbes a “magazine” that has nothing to do with technology called it “timeless”? Well, that got me convinced.

Shouldn’t this stuff just be labeled an ad in BoingBoing?

9V is about 19 kJ, while a AA is 15 kJ. In addition, there is a minimum voltage required to activate most types of circuits and this is related to voltage bias necessary for a semiconductor. Even a “joule-thief” circuit can’t bring this minimum required voltage down to 0. This means a 9V can be discharge proportionally more than a single AA.

Of course a 9V weighs more than a AA. It takes up significantly more volume for the amount of energy it offers. It is more expensive. And uses more material for the case and partitions of cells than a single AA cell.

Two AA’s beats one 9V in just about every way imaginable. Not only because 3V (1.5V * 2) is a very usable voltage for modern electronics, but you also have more 50% more energy in 2xAA as compared to one 9V.
