Looking for: powered USB A to SATA 3 disk adapter guaranteed capable of more than 1.5A on 5V to SATA disk

I've found many powered USB to SATA adapters, but none specify the current supply capability in the sales materials.

I'm in Sweden, if that matters.
The higher the current capcity the better, and of course USB3 is preferred, but >1.5A on 5V (to drive a Samsung EVO 250GB SSD) is the important bit.

Just go to your local electronics store and get a powered USB hub. This should cost very little and will do what you need.

Good luck.

You'd need a lot of luck...
Both my USB to SATA adaptors fail, even the one with a separate power supply. And, my powered hub made no difference, probably because I compared it to using the adapters via my computer's USB connector, which is powered.

Or, am I misreading you, somehow??

Yes, you are misreading what I posted. There are external USB hubs that you can use to expand the number of USB ports your system can use. These external devices have their own power supply, which in turn delivers power to the attached USB devices, like a SSD or HDD. See below for an example.

This model can also support a directly connected SSD/HDD.

You could use something like these docks/enclosures for a SSD/HDD.

OK. Will check what can be found here in Sweden.

You still may not get what you want, and maybe that's because you are looking for the wrong thing.

USB2 ports are limited to supplying no more than 0.5 amps to a connected device. Newer USB3 ports have raised that to 0.9 amps. So, asking for 1.5 amps from any standard USB port is not likely to work.

Powered USB3 hubs do come with their own power supply units that can supply to the hub much more than 0.9 amps. BUT that's in TOTAL for many hub ports. If the hub is designed properly to meet the USB3 specs, EACH port still will only supply up to 0.9 amps.

Now, I suspect you are trying to connect a desktop-sized HDD to a computer using a USB port, preferably USB3. Thus the problem is meeting the power needs of a large HDD NOT designed for low-power use in laptops. A powered USB3 hub is not the way. Instead you need a SATA HDD docking station that connects your HDD to a USB3 port BUT also comes with its own power supply module. Such a unit is designed to supply enough power to a desktop SATA HDD directly from the power supply module, and NOT try to get power for the HDD from the USB3 port. Only data communication happens using the USB3 port.

Here's one example of such a device:

It will work with both USB2 and USB3 ports (obviously, USB3 is much faster data transfer) and any SATA HDD (2½" or 3½") because its power module can supply up to 2.5 amps. You may not be able to buy easily from that on-line supplier, but you get the idea of what to kook for.
