BMAX y13 – USB-C not charging

[sandro]

Guys, I still didn’t get what feature is needed for the charger to charge this laptop!

The Y13 spec suggests PD2.0 but I honestly don’t think my cheap charger has even that (see earlier post for link). My 2ct is to try a generic one with at least [email protected] or a high wattage PD2.0.

I am successfully charging with this charger in my van:

1. Hi dude, I was trying to figure out how get my bmax y13 to charge using usb-c then came across your comment. I know it’s a couple months late but I had the same problem. I resolved this issue by increasing the minimum process state whilst on battery power to 55%.

You need a charger that uses QC 3.0 and usb-c to usb-c wire. Same for PB. Search imuto hub QC 3.0 on Amazon. I got one for around 18 quid.

[sandro]

It all seem to point to pd 3.0 and or qc3.0.

I’m still confused.

I bought this charger that has a 36W output from the usb-c port along with a 100W cable and it works, however still stuck at 11.4W charging speed like the DC charger so I guess you won’t ever get a higher wattage.

Sandro, ese cargador de Ugreen tiene sólo 18W en cada salida USB. El que trae la notebook da 24W. Te recomiendo el que analizan en este artículo:

Yo lo compré y carga la Bmax más rápido que el de 12v y 2 amp

 

[sandro]

The Ugreen actually charges at 36W max so it should be faster tha 11W, even so why not at 18W anyway?
What power are you getting from that charger?

[sandro]

I tried with a PB from amazon with 12V1.5A via type-c with QC3.0 and PD3.0 support and it’s not charging. Go figure what’s actually needed.

[sandro]

Edit: it does work, sorry. Always at 11.4W though :/

Edit 2: it says charging but I guess it’s not, probably the PB is not delivering enough amps even if I see 11W, thepercentage is not increasing.

[sandro]

Edit:3 I received another PB, this time 37Wh (can’t post links)
that like the other one it supports 12V1.5A and it’s charging. While I see the percentage of the battery decreasing 100 to 86% the laptop percentages stayed the same for an hour almost in idle. I don’t understand, where is exactly that energy going? :/
Considering this formula (can’t post links) I should get around 2700mah which is half the battery capacity filled.
I’m assuming that both these cheap PBs don’t delivery enough amps to fill the battery while the laptop is on.
I don’t have a watt usb meter for usb-c so I can’t tell for sure.

 

 

sorry I had to delete links otherwise this wouldn’t post.

I use Omars 24000 mAh.

[.oOOo.]

My original post is lost somehow. Probably because I edited it one time too many. I can not repost it because the forum software detects that. Here it is again, hidden as a quote.

After buying three power banks (none worked) I decided to buy a USB-C tester from Aliexpress (search for 32816538942).

The tester reports that my BMAX Y13 charges at 15 volts, not 12 volts like I thought it would. If I connect any of my PD power banks the BMAX negotiates 9 volts and it doesn’t charge.

And yes, it is definitely a BMAX problem. I have one charger that doesn’t work if I connect it directly (tester shows 9 volts), but which does work if I put a HDMI dock between the charger and the BMAX. With the HDMI dock in between, the BMAX will charge at 15 volts.

@Octavio : I tried your power bank from Aliexpress (search for 4000191871773) but it also connects at 9 volts. 🙁
