Charging loop using ASUS USB-C PD on the Asus ROG Strix G713QM-ES94
Charging loop using ASUS USB-C PD on the Asus ROG Strix G713QM-ES94
Hello everyone! I recently purchased the newest Anker 737 PowerBank (24k/140W). When I connected it (using the included cable, which supports up to 140W) to my Asus ROG Strix G713QM-ES94 via the USB-C PD port (located at the back), it only reached 9W and then stopped, repeatedly looping. Using the previous cable from my earlier Anker power bank (26800 PD 45W) worked much better, delivering around 58.5W while charging. Both cables are from Anker and came with their own power banks. I don’t have another PD device that can handle more than 100W, but with the 140W cable it charges to about 89W using an Anker GaNPrime 120W (which supports up to 100W total on either USB-C port). I’m unsure if there’s a driver problem or something else at play. I also tested charging my PC with the GaNPrime 120W charger—it worked fine, though I don’t know the charging speed. I returned my old power bank for a replacement, but it behaved the same. When I used the new cable with the notebook off, it charged slowly (~30W) and then shut off completely. I tried uninstalling the battery driver in Windows (recommended by ASUS) but the issue persisted. No idea if it’s a driver issue or another hardware concern. Thanks for any help!
I considered it, but it seems unlikely. I returned the original power bank to Anker, and they replaced it right away after I provided proof of the faulty unit. That means both cables might be defective? Charging your notebook with the same cable using the 120W (100W over USB-C) GaNPrime charger and avoiding any loops is possible. The charger supports up to 100W through USB-C, and your notebook also operates at 100W via USB-C. The power bank can deliver up to 140W through USB-C, but it will only charge the notebook at its maximum of 100W since the device limits power. For a reliable USB-C PD cable, you can look for trusted brands on Amazon; I don’t have specific brand suggestions but checking recent reviews would help.
Indeed, weird, my bad. Seems possible to me, they always send that powerbank with an unperfect cable though. It'd be nice to try to charge another laptop. I can't really vouch for them as I didn't check them thorough but I like the Ugreen and Baseus cables from Aliexpress. Did you tell the Anker people " I did use the old cable from the previous Anker power bank (26800 PD 45w) I had and it goes up to ~58.5w sustained." ?
I don’t have another laptop that supports PD. I considered visiting a large store with compatible devices, but I’m currently in Italy and don’t speak Italian. That makes me hesitant about going there and using a power bank without knowing the rules. I mentioned the cable to Anker, who said it might be faulty and suggested using the warranty for a replacement. Still, I’m facing the same problem. I’ll look into the cables but might need to transfer them to Italy somehow. I also need a 140W cable, and Anker and Ugreen are around $30 each—way too much for just testing.
I just installed the new cord, but the same problem persists... something unusual has been reported where a loud noise occurs on the laptop, especially around the battery area, as if a relay or similar component disconnects when the Power Bank drops to 0W.
Sorry to hear that. Perhaps 140W exceeds the NB limits (refer to https://www.asus.com/support/FAQ/1042209/). It functioned with the previous cable since that one supports up to 60W and NB permits that. Disappointing that the system can't reduce and gives 100W while 140W isn't allowed. PD should be backward compatible; you might inquire with Anker or Asus about the PB's downgrade policy. Likely a 100W cable would work like the 60W one, which could be better (see https://www.asus.com/support/FAQ/1042209/).
I managed to link the HUB I previously overlooked, and the pass-through function works well with it. It handles up to 100 watts, and once I connect the new power bank, everything functions smoothly—reaching up to 88 watts with stable performance. I’m definitely going to use that...
