What board should I use to trick a Anker 333 outlet expander to provide 12v/1.5a from it’s usb A port to my Alarm clock via a usb A to DC 5.5x2.1mm cable?
According to the user manual it has a maximum power output of 15W and is 5V only. Note: that only works with the USB C port, the USB A ports are limited to 12W.
- 12V@1.5A is 18W.
- To convert from 5V to 12V you will lose some of the available power.
- So there is no way to get 12V@1.5A from this power supply.
User manual:
You probably could get 12V@1A out of the USB C if you used a >85% efficient step-up switching power supply to generate the 12V.

This is the device I have it is rated for 18w

Hello Dfiddis,
Does this device not already output 1.5A @ 12VDC? Looking at the specifications on the document provided, they have this:
If this is not working, you may need to contact Anker support.
I don’t know of any pre-made solution.
If you can solder up cables you should be able to use this USB PD controller board to get the 12V output

Hi dfiddis,
@PaulHutch has found a possible solution. You’ll need to be able to solder to use it, as you have to place a solder blob to short the 12V selector pad and cut the 5V selector pad.
Then you’ll need to solder a cable to the board with the 5.5mm x 2.1mm plug, such as one of these.
Or, since you have 6 standard outlets available, you could just use one of these.
Would this work:

And if so do you sell an equivalent?
The answer to your question about if a 99 cent boost converter from overseas would work is maybe, if you trust the 4 reviews it has are legitimate.
But that pushbutton switch on it toggles through the voltages 5V through 20V. Can your device handle 20V if you accidentally switched the voltage that high?
Do you want a device that you can easily accidentally set to 20V? It seems like a device where you have to solder a jumper to guarantee a voltage output would be better suited.
Hi @dfiddis
Just curious, what kind of alarm clock requires 18W of power? Utilizing Nixie tubes?
Cheers, heke

It has a 10w wireless charger, 2x 5w speakers & 5v/1a Usb A port
It actually wants 12v/2.5a but the outlet expander can only give it 1.5a & when I tested it with a different 1.5a power supply it did everything I needed it to do.
I can’t use one of the AC outlets because there all in use & the usb c port is charging my phone
Can I get the recommended board in a version with Male & Female Usb A ports?
I can Solder but not very well
I couldn’t find anything for this kind of boost circuitry with USB A Male to USB A Female that we carry. Also, you wont see many devices designed to have higher than 5V on a USB A Female port.
You’re going to find if you get above 15W you’re much more often going to see USB Type C connections these days.
Looking at the fine print on your Anker device, the USB-C PD outlet only goes up to 9V, so that connection is out. The USB-A outlet uses “USB IQ” protocol rather than “PD”.
We have a solution for PD, but not for IQ (that I am aware of, at least). “PD” and “IQ” are different protocols that USB power supply manufacturers use to negotiate voltages between the source and the consumer of power. If you had a different device which provided higher voltage options on the USB-C connection, then we carry a few interesting parts that would take care of you.
Specifically, the 1528-5450-ND is a USB-C to 5.5mm x 2.5mm cable with a tiny chip embedded which tells the PD source to provide 12V at up to 5A. We get this from Adafruit, and they claim that the spring inside the device is stiff enough that a 2.1mm male tip will still make sufficient contact.
We also carry a USB-C to 5.5mm x 2.1mm adapter, the 1528-6032-ND, which also has the same chip in it to make a PD request for 12V.
So, I would recommend you either get an additional extension cord with multiple outlets and get the plain old power supply I mentioned above, or get a different unit than the “Anker 333 Outlet Expander” which has a USB-C PD outlet which can output 12V, and then pick up one of the two items I mention above to get the 12V plug you need for your tricked-out alarm clock.
According to ankers website
- Power IQ 1.0: Supports 5V/2.4A max
- Power IQ 2.0: Compatible with QC 3.0 + Power IQ 1.0
- Power IQ 3.0: Compatible with QC 3.0 + PD 3.0 + Power IQ 1.0
- Power IQ 4.0: Compatible with QC 3.0 + PD 3.0 + Power IQ 1.0 + Dynamic Power Distritution(automatically detects and adjusts the voltage output of connected devices and shortens the overall charging time)
I believe the usb A port is PIQ 2.0 so it should be compatible with QC 3.0, do you have a solution for QC 3.0?
I am not aware of any similar products we carry which use the QC 3.0 protocol. Most everything I have come across has been PD protocol products.
