Warning: the port labeling suggests that this device supports up to 60W. However, the device is limited to 30W charging. This will significantly complicate using any more than two ports at once without understanding the loads of the devices you attach. There are definitely some convenience charging scenarios where this could provide some value, but this should only appeal to a very niche set of users.

Good luck!

It's far from being as simple as an AC power strip (where the incoming voltage is shared across all outgoing ports). Even the cables in USB-C aren't completely passive (cables rated for 3A or less identify themselves in truly passive ways using resistors, whereas 5A cables identify themselves with an e-marker, an active chip!).

Instead this device accepts an incoming Power Delivery 30W source. Documentation is unclear as to whether this supports 15V 2A and/or 20V 1.5A as the 30W source.

I would guess (without better documentationf from Belkin) that on the output side only 5V is output at up to the current (amperage) limit of the associated port type: up to 3A for USB-C, or up to 2.4A for USB-A. This is created through DC to DC power conversion taking the incoming higher-voltage (15V or 20V), lower current (2A or 1.5A) source and transforming it into a low-voltage (5V), higher-current (up to 3A in a single USB-C port, up to 6A across all ports max.) supply. Note that it is possible that higher voltage profiles might be supported on the USB-C output ports, but this would be surprising given the low output power ratings. As noted below, this device only supports 5V output.

Sorry if this is a bunch of technical stuff, but know that the short version is that the Belkin device is far from passive. Rather, it is an active power converter that must convert the incoming voltage as well as negotiate with any connected devices being charged,

Good luck!
Jon

Open box $3.99 with free shipping is a better deal (obviously ymmv), although I don't need it even at that price.

I've had this device for a while and using it. I can confirm it doesn't do any more than 30W total output. You can connect it to a 65W, 30W or 100W charger, the Output is always 30W. When more than 2 devices are connected the power is shared across all devices.

With 4 devices connected - ideally it should be 7.5W per device. However, on actual observations it's more like 7.5W for the USB C and 5W for the USB-A.

In short, it's useful to charge lower power devices such as earbuds or smartwatch- but really not superuseful for 2 or 3 phones together.
Then the "boost-charge" labeling is clearly a scam! It should be labeled "reduce-charge"!

I've attached a picture of the back of the device. Input requires 15V/2.5A (37.5W)

The USB-C ports max out at only 5V/3A (15W). The USB-A ports max out at 5V/2.4A (12W). Total output between all 4 is 5V/6A = 30W.

Despite this, it's not a bad "road trip" charger where you don't need blazing fast USB-PD/PPS speeds. I'd argue the convenience of multiple ports would benefit in certain scenarios. If you needed a 100W USB-PD charger there are plenty of other deals.

Great detail. Makes sense given power conversion losses that to deliver 30W max this device requires 37.5W max. Also important to note the requirement for the 15V Power Delivery mode (at up to 2.5A).

Thanks and repped.

Good luck!

This will come in handy on an upcoming trip where sometimes outlets are not in the most ideal locations.

From the Q&A section:

"Hi GaryR. The Belkin BUZ001 has the following power specifications: Total output: 5V / 6A 30W max Max output per port: USB-A 1 / A2: 5V / 2.4A USB-C 1 / C2: 5V / 3A When four ports are used: 5V / 1.5A each Furthermore, it is best to plug the device into a power source that provides at least 30W."

Hope this helps.

Basically. It's removable -- it slides in and out.

does it need that specific input voltage and power?

It doesn't seem to do anything when I try to use it in my toyota USBc plugs

The port has to be capable of 30W PD. Many cars USB C slots might not have that. Maybe it's a good idea to connect it to a higher wattage charger using the power outlet.

thanks, i think i will have to use the 12v or the 120v outlet first!
