Slate AX requirement for 4A adapter

Johnex · 2022-07-01T10:52:52.530Z

Also keep in mind when using a smaller power adapter. The lower rating it has, and the more amps you pull, the hotter and more stressed it will be. If you are using a cheap china brick it might even be overspeced, and you come a gutser.

If you decide to go with a 2A adapter and you are running it at 1.9A constantly, it will be super hot and might die very fast. I like to always add 1A or so headroom when it comes to power conversion (even DC to DC).

If you will be running the router at home, use the included adapter.

If you decide to use another adapter and something happens or you have data loss or something else, it was at your own risk

Also, there has been a big effort to bring the little externals within the 500ma spec of USB2 so you don’t have to have the Y plug anymore. The bigger capacity 2.5/1.8 drives are usually USB3, so you can’t tell, but if you have a USB2 drive without a Y cable, you should be in good shape.

Ravpower PD Pioneer 65W, works from USB-A ports on the charger while my laptop is hooked on USB-C output

NomadTony · 2022-07-23T18:33:39.036Z

Does it stay on if you plug/unplug other devices from the charger? Or does it reboot if you do that. (ie device being plugged in or out of the RAVPower charger. Thanks!

router didn’t restart upon connecting/disconnecting laptop from the USB-C port

I would suggest Glinet to use USB-PD for future models.

beniamin · 2022-08-03T13:32:23.469Z

I would love PD. With how much space there is in these mini routers now it shouldn’t be too hard to solder one in place. They’re very tiny.

Why? PD is really for batteries.

y2kbug · 2022-08-03T15:34:28.143Z

Couldn’t USB-PD be used for power supply as if USB 5A 1A or 2A? I really don’t know.

elorimer · 2022-08-03T16:32:02.319Z

PD starts with 5v 3a, and then can negotiate up to 20v 5a if the cable, charger and device support it. But the USB3 A port is only ever going to be 5v. The point of PD is really to charge batteries faster than the USB3 spec supports.

PD power adapter can surely be used to power the router.

The only problems is that, as @elorimer said, PD is designed to charge batteries faster. So it will talk with the device (e.g. phone) to find out the correct output. This will cause short power cut. While this is not a problem of batteries, it could cause the router reboot.

So PD power adapter be used to power the router, but it may cut power sometimes causing the router reboot.

Any recommendations for a car adapter to power this thing? I want to connect an SSD to it for hosting media on a couple of tablets.

I’m surprised that the Slate AX is coming with a 4A adapter…My FLINT came with a 1.5A adapter…Which works fine for the router but seems low especially now that I see the SLATE AX coming with a 4A adapter…I swapped a 2A adapter on it and that works fine…I looked in the GL.iNet U.S. (Amazon) to see if the 4A adapter was for sale as an accessory but did not see any. (Don’t want to pay shipping from HongKong on an accessory adapter)…

You can find cigarette-type USB3 plugs that will give you 3A, but I think that is it since that is the limit of the USB3 spec. You’ll have to see what the SSD draw is–some are a lot more than others–to see if you can live within 3A.

You can also find cigarette-type PD versions that will go up to 30 watts, but only 2.4A at 5v. Those would be worse for you.

Slate AX 5V4A
Flint 12V1.5A

Pls note the the voltage rating.

potatoe · 2022-09-05T15:17:03.148Z

So I guess 5V/3A like this one Anker 40W 2-Port PowerIQ 3.0 Type C Car Adapter will suffice?

motox22a · 2022-09-05T20:24:52.883Z

Yes…I substituted a 12V 2A adapter in place of the Flint’s 12V 1.5A adapter. I may subsitute a 12V 3A adapter if I can find one at a decent price.

This question is relatively old as the Slate AX has been out. I just purchased mine. My first question was why the “big” power brick. Reading the comments here I am a little surprised by some. Such as PD is for batteries. Which is outright wrong. Both my Dell laptop and MacBook Pro are powered by PD over USB-C ports. Note both are also Thunderbolt ports. I use a Dell dock for the Dell laptop and a new GaN 200W charger for the MacBook Pro. The latter charger has a display showing how much voltage and wattage is being provided on each port. I plugged the Slate AX into the 2nd USB port and you can see the results in the picture below.

I also decided to try my 240W battery with 4 USB-C ports to power my new Slate AX. The battery also has a display but it only shows wattage being delivered on the port, . It shows 3-4W being delivered just as the wall charger in the picture. I don’t know how that works out into voltage and amperage but I assume it is the same as the wall charger.

I don’t see any reason why a USB-C PD charger won’t properly power the Slate AX. It would be nice to know officially if the Slate AX works with a PD charger. As in does the USB-C port actually support PD.

Actually I have said multiple time in this post. So here it is again:

PD charger works with AXT1800. It means PD charger can output 5V3A and is enough for the router, without extra USB accessories.
AXT1800 does not support PD protocol. This means it only accept 5V, not 9V, 12V, 15V, 20V, 28V, 36V, 48V. As all PD charger support 5V so this is not a problem for the router.
Some PD chargers, may disconnect power of all port when it start to negociate with new connected device. This will cause the router reboot. So not ideal. But if your PD only power the router, or do not disconnect/reconnect devices that is OK.

rdolivaw · 2022-12-21T15:36:06.021Z

Thank you for replying to my post anyway. I have done a little more research and learned that USB chargers and cables prior to PD supported 5V. So if the attached device can’t negotiate PD or your USB cable is not PD compliant, then you get the legacy 5V from any properly built charger.
