amazon is the biggest online retailer in the uk statista.com/sta…es/
Interesting that it has a plug on but what sort of stuff would you realistically be able to run on it?

It's designed for portable goods. So cameras, drones and even laptops. Although it will only supply 65w so not gaming laptops. But many gaming laptops you can turn on power save mode and run off the iGPU.
It's ideal for people who travel and want to keep their mobile and thin and light laptop charged up.

A third of online shopping globally is via Amazon. That is a staggering figure.

cos otherwise it's just Gearbest, Gearbest, Gearbest!
Prefer this to the newer one due to 3 pin socket, not sure if I need it or not, just want for the coolness factor! Already have a 20100mah battery pack,

So its steps the internal battery voltage upto 250 volts, you plug in your laptop charger and that drops the voltage back down to 18 V. Madness

Yes basically you are paying for the DC to AC converter. Then your laptop brick is an AC to DC converter. But you can use other AC power products, like to charge an electric razor. You are paying for convenience.

If it were me and I was only using it for my phone and laptop I would probably find a normal power bank and find one with the the highest group of Amps from the 5v ports and make up a ghetto lead with a DC-DC boost converter. But that's just me.

This makes no sense surely - it already has a USB C port?

The dedicated USB type 'C' port only supports 5v. So fine for a phone but not a laptop.

Well yes its about prices but the retailer makes a big difference as to whether something is a good deal or not.

That's probably the most efficient way but would the conversion to AC and the step up be that inefficient? Presumably if it were they wouldn't do it?

When pulling 50-65w AC I would expect it to be around 90% efficient. As this drops off so would the efficiency. Then your laptop brick would also be of similar efficiency.

As I said it's not ideal but certainly very convenient.

So something like this with male USB A on one side and whatever goes into your laptop on the other plugged into something QC3.0 compatible?

I think I even know someone with a 3D printer who'd be able to produce a small plastic surround for a board like this...

First adding QC make it very complicated and you would need a QC force board to change the voltage.

The boost board linked is a bit weak but could be used. Finding one that supports a few more Amps would be better (or use more than one of the one you linked to). Ideally you would want 3x male USB on one end to pull the maximum amount of Amps at 5v to give you the maximum amps on the output at 12v-19v depending on your laptop. You will need a multimeter to check the output voltage.

TBH nobody seems to be doing it but would make a good project/bedroom business. If you aim at ultrabooks (or other laptops with fixed batteries) you could probably charge £20-£30 for a cable that would only cost you £5 or so to make.

Okay, so 3 USB male one end hooked to two of these boards in parallel? I'd just double the height of the 3D printed enclosure and specify a plastic spacer to go between them. I likely never find the time but if I ever do go into business I'll PM you about your paying your consultancy fees. Thanks.
