2017 Laptops USB-C Power Delivery Compatibility with External Power Banks

[ricer]

[quotemsg=20628864,0,2645084]My company makes two 45W USB PD chargers: a power brick and an external battery pack. The power brick can provide 45W at 20V/2.25A, so with all likelihood, it will work with Razer Blade Stealth. However, I do have doubts about the external battery pack which pumps 45W at 15V/3A. Will the battery pack work with Razer Blade Stealth? I can provide a free sample if you or anyone else would volunteer to test it. [/quotemsg]

I just bought a brand new razer stealth with the 8th gen CPU. I'd be more than happy to test your battery pack and post a YouTube video of it.

[quotemsg=19648373,0,2468911][quotemsg=19423358,0,2398439]There are 2 types of ravpower - the old one and the new one,the new one has a usb-c output and stuff. I don't remember which usb c cable I used, but yes, the one before that simply didn't work at all, so I bought at the apple store their 61W usb-c wall charged and a cable (which I tested right there), which I use with ravpower too.

And yes, I tried Asus zenpower max with my HP - it's simply not charging at all, why - not sure, most likely you are right-not enough amps.[/quotemsg]

Eugene, can you provide a link for me? I have tried 2 ravpower and an aukey with no luck at all. Also did you say the cable matters or does it work with the cables that come with ravpower?[/quotemsg]

I'm kinda obsessed with the whole Power Delivery thing too, but I think there are more (and better) alternatives for Ravpower, you guys definitely want to check this out:

I own one of their A2 products and it works fine, ordered the A3 already. Doesn't even matter anymore wheter you power through USB C or anything else because this bad boy has USB C PD + an AC outlet for all other laptops...(and two 3.0 USB ports) I own an HP spectre 13 and bought a Power Delivery charger from the same brand, these guys know what they're doing.

And yes cables definitely matter, PD is possible when a cable supports 20V/5A for example (see indiegogo link)

[quotemsg=20770210,0,2675077]How can you tell if a laptop supports power in through usbc, unless that was the default method like Mac book?[/quotemsg]

Well mine has only 3 usb-c ports so that's abvious. For others you should check a review to be sure, if there is no other charging port or if it's advertised with 'Power Delivery' it can be charged through the usb-c port. But even when it has another charging port it is still possible in some cases (the Samsung Notebook 9 is an example of that.)
