PowerFalcon PD laptop charging cable







This is a cable to charge any laptop with about 20V charge voltage from a USB-C PD charger.









It arrived in a cardboard box.







It is a cable.







One end is a USB-C connector, that must be connected to a USB-C PD charger that can deliver 20V







The other end is a replaceable laptop power connector. This connector can only be connected one way, there is no risk of wrong polarity.













Eight of them in a nice strip, the last is on the cable, this means a total of 8 different connectors.







This is the official compatibility list.







Measurements

  • Uses PD mode: 20V 3A

  • When correct PD mode is missing it will enable 5V

  • Uses about 16mA for its internal electronic

  • For testing I used the G plug (5.5/1.7mm) it fitted nicely into a 5.5/2.5mm socket.




The voltage and maximum current depends on the USB-C PD charger, because the cable is using 3A mode my charger shuts down a bit above 3A.



I did a 1 hour test at 3A to see if anything got hot, the photos below are taken after about 45 minutes.



M1: 33.8°C, HS1: 36.7°C
Not surprising a rolled up cable gets hotter when the different turns can heat each other, but nothing serious. The cable is thick enough for 3A charge in rolled up condition.



HS1: 42.0°C
The USB-C plug gets a bit warm, but again nothing serious.



The laptop plug has some temperature increase also, but again it is perfectly acceptable.



Conclusion

The cable works nicely, but requires a fairly powerful USB-C PD charger.



Notes

I got this cable from reader “Mostly Melbourne”

For testing I used this USB-C charger

Would 20V be an issue for a laptop that normally takes 19V? I’d assume not, but I don’t want to risk it myself :stuck_out_tongue:

I would not expect any problems with that.

There shouldn't be any problems, just shouldn't.

I once tried a genuine HP 19V 90W (PPP012L-E) power supply on a Dell Vostro 2520 (stock supply 19.5V 65W) and on boot up it complained of a weak power supply. Of course that was wrong and due to the slightly lower supply voltage.

Thank you for reviewing this. I have always been interested in such a cable and intially, wanted to get Innergie’s 60C + their laptop cable, just to realise the cable will only work with their charger,

interesting cable, reminds me of the block power supplies of the 1980s where you had adapters for each device.

Remarks:

The above connectors' image has an incorrect aspect ratio at the given size (866 × 576) due to stretched height. It looks about correct at 866 × 480:

HP uses a big tip whose dimensions are 7.4mm × 5.08mm outer/inner diameter, with a center pin. It looks quite close to the leftmost plug in the following picture:

However, I cannot find a direct match for it in the above table (other than the 6.5 × 1.4mm Sony/Samsung reference, I mean).

Seriously?
