    Hey all- new to the community. Just picked up a razer blade stealth as my work laptop and loving it so far.

    I was really excited to see USB-C charging as a feature on the laptop, but when i tried to use both my anker powerbank and my anker USB changer, the laptop didn't recognize them as power sources. I'm wondering what the requirements are needed in order for a power bank to be recognized by the laptop? My best guess is that it needs Qualcomm quickcharge 3.0, but would love to get confirmation on that before I buy a new powerbank. I know the new razer blade stealth has a higher wattage charger, but I'm not sure how that translates when using a battery pack. Thanks!

    It needs USB-C PD with at least 45 watts. The 8th gen may be 65 watts (I have 7th).

    I have the razer power bank, it works great but gets damn hot when using it with the RBS. I wouldn't trust a 3rd party one.

    Yeah the new RBS w/ the quad core uses a 65 watt charger, so I was wondering if the razer power bank would even work.

    It should negotiate down to 45 watt, which is kinda the point of USBC-PD. This sounds like a good question for the razer support.

    The razer power bank supports:
    USB Type-C | 5V 3A / 9V 3A / 12V 3A / 15V 3A / 20V 2.25A
    USB Type-A | 5V 2A / 9V 2A / 12V 1.5A

    It's rated for 46wh, which seems low for the price until you consider it has a buck and boost smps (most cheap power banks just dump out whatever the pack voltage is) and is in a nice aluminum box and comes with nice braided cables and has the meter LEDs on the side, and I could go on and on.

    The RBS has a 53.6 wh battery, so the power bank doesn't quite get you a full charge. In practice I've noticed it will get you from dead to about 70% while the laptop is running.

    Finally, last year I bought a 44++ battery from lenovo for my thinkpad x220 that came in around $170. And it ONLY works with the thinkpad. In case other people claim that the power bank is overpriced.

    Nice gadget, I really like it.

    No, it doesn't even come close:

    I wouldn't trust that Anker brand, I had purchased a thinkpad T60 battery from them around 2013 or so and during it's second cycle it became so swollen it ruined the whole laptop and melted itself. Without shutting down.

    If you insist on a non-razer power bank, at least get one that uses quality cells like panasonic or LGC.

    Oh I'm sorry for your loss
    I had anker power bank's for at least 6 years, never had a problem.

    Don't get me wrong, if it's available I would consider the razer one. But I don't feel like shipping from the states since eu/ger/aut stores don't have them

    We have Amazon, just try it and if it doesn’t work send it back. I’m using Razer powerbank though, but have also Xiaomi Air 13 with mx150 which also could powered by it. Xiaomi has also powerbank for their notebook with around half price cheaper I think, and I’m guessing it works also with stealth, but you have to import it through importer like Gearbest.
    Razer powerbank could even power latest MacBook 15 dGPU (Radeon?), so i prefer it over cheap PB out there for laptops, I’m using €10 10.000 powerbank from mediamarkt Sale to charge my IPhone though;)

    Ah, this thread is about the new RBS with 65w supply.

    I'm on the road so don't have time to link specific power banks.... But the Ravpower brand is phenomenal for portable chargers if you needed something bigger than Razer's. I personally love the Razer power bank because of the aluminum build.

    Hey all- just an update on this anker charger: https://www.amazon.com/dp/B072K5ZJX...JG&pd_rd_r=WJGXKBRYKPYS95B6XSEP&pd_rd_w=UU5Fm

    apparently it only allocates 30w to the USB-C PD. it pretty much works when the laptop is docked (hovers around 97/98 %) And works with the laptop as long as the screen brightness isn't maxed out.

    Still hoping that they come out with a USB-C charger that delivers higher wattage.

    So if laptop works with 30w supply it should work just fine with 45w razer power bank and maybe charge the battery more slowly?

    Just buy €150 Razer Power Bank, on this one they should use expensive parts;) it could power xiaomi Air with 150mx, or even MacBook Pro 15 easily, for Stealth it’s not problems at all, but I don’t use it often with stealth because I never had battery low warnings on stealth, I always plug it at home on the wall or Core, when I go out the battery already hold a Day I think, unless I play some games on it.

    The razer power bank has output of 45w. The new RBS requires 65w.

    18 posts in and no definitive answer yet. :confused_: Although it kinda-sorta works with 30w, apparently, although not well.

    What, how a UCPU need more power than MacBook Pro 15, it comes I think with bigger 85w power adapter, I tested Razer powerbank and it worked well.

    Just because apple implements usbc-pd correctly, doesn't mean razer does.
