Well, folks, I got a new meter! First test: powerport Speed PD and PD wall charger.
First of all, the test device is an asus flip c302 chromebook with USB C power delivery. The wall charger in this bundle measured 24.3w, edging up toward the 30w advertised speed:
It's probably a result of the computer's uptake speed rather than the charger itself. I'll investigate that in future posts.
Next up, the powerbank. About the same speed, except the powerbank appears to stop solid at 15v, replacing the rest of the 23.55w with amperage. Again, I think this product could push more than that, I'm going to confirm in later tests. stay tuned.
Next, we have a Moto Z2 Force Edition, pulling a respectable 16.27w from the wall charger:
And 15.38w from the power bank:
Verdict: both parts of this bundle are capable of providing PD in the mid-20w range. I suspect I can find a device that will pull the full 30w, will update this post in comments when I have time for further testing.
Thanks for reading!
