asus ac68u router voltage

[ColinTaylor]

This is what I am talking about . This type of the ups we have here in my country < the problem it doesn't have a 19 volt outlet to operate the router I want to have.

So what is the make and model of the 850 VA UPS you were talking about in post #9? Do you already own this UPS?

 

[aligh]

I see now. It is not a ups like I originally thought.

this is what we have here : https://smartkey.manufacturer.globa...ni-Ups-Dc-UPS-UPS-mini-ups-12v-router-ups.htm

No I don't .I am talking about a replacement for the ups that doesn't have a 19 volt outlet. The the 850 VA UPS is used fo r computer ,it give you any voltage you want but it doesn't last for a long time like the other kind in this link : https://smartkey.manufacturer.globa...ni-Ups-Dc-UPS-UPS-mini-ups-12v-router-ups.htm

forget it - not usable with this more power hungry router!
It is 1A only @24V and you would need about 1,75A or in other words limited to 24W, your router needs 1,75A x 19V=33W.

Yes, It is only POE 36W. you mean this ups is useless because the router need more energy. in addition the nano also need power . What is the other solutions ?

 

[aligh]

I’m confused. Shouldn’t he be plugging in the routers 19v power adapter into the 24v ups? Is so wouldn’t it be running as it normally would be if plugged into a wall outlet?

this is the ups I talk about https://smartkey.manufacturer.globa...ni-Ups-Dc-UPS-UPS-mini-ups-12v-router-ups.htm

This type of the ups we have here in my country

This is not the only type available, I believe.
Can you get a normal UPS with AC output and use router's power supply?

yes I can , but the normal ups doesn't last for a long time just an hour or less , while the special ups which design for the router lasts for about three hours or more . It 's complicated ha ha ha

what do you think of this it gives 19V but 1A. Can it run the asus ac68u ? here the ups : https://www.alibaba.com/product-det...pm=a2700.7724857.normalList.80.2d26655bTw6BdH

The label on the back of the router clearly states 19v and 1.75A. You might be lucky and get away with it provided you don't have any USB devices plugged into the router. But you do so at your own risk and might potentially burn out the UPS port or damage its battery.

It all depends on what capacity battery the UPS has. The router's normal power consumption is about 15W or less. A normal UPS is more universal, you can use it to protect other devices too. Keep in mind UPS is not a power source. It's a protection device to supply power in short power interruption periods and to allow sufficient time for electronics to shut down properly. Batteries in UPS devices work in a heavy duty cycle and if you drain them completely and recharge often they won't last for very long.

SC-DC6S is rated 12000mAh or 12Ah with a lithium battery which means about 3V.
12Ah means it can give 1A for 12 hours, or 0.5A for 24 hours, something like that rated with 3V output.

So 12Ah @3V means 36Wh (watts for one hour, or less watts for more hours).
Your router usually will run with roughly 15W (1.75A x 19V=33W is maximum for short time while powering up), this SC-DC6S will last about 2 hours while SC-DC3S only 1 hour.

You will find this line: Output interface:2*USB/5V-2A,5V-2A,9V 2A,12V 2A,19V 2A,24V 1A; B25

So it should be fine for your router only for less than 2 hours.

EDIT: system voltage is 12V not 3V as I thought, so it will last 3 times longer! (thanks to Colin Taylor)

Your router usually will run with roughly 15W, this SC-DC6S will last about 2 hours while SC-DC3S only 1 hour.

But it as well says: Discharging Current: 2A what will possibly be the maximum value!!!
That means 2A @3V but you need 1,5A @ 19V which means it will discharge with 19V/3V=6 times more ampere.
So you would need 1.5A x 6 = 9A discharge current on the batteries.
That one might not deliver that much as it is rated with 2A!

The specs say that it has a system voltage of 11.1v with is consistent with 3 18650 lithium batteries. So that's 11.1 x 12Ah = 133.3Wh. Assuming his router only draws the 1A allowed by the port (rather than the maximum 1.75A required by the router) then it would last 133.3Wh/19W = 7 hours. Although probably more like 4 or 5 after accounting for losses (assuming nothing else is plugged into the UPS).

so what do you think the asus ac68u can work on 19V 1 A in this ups or not ?

What do you mean by this ( SC-DC6S) ?

@ColinTaylor: thanks for correction, didnt see this line system voltage, only that they use Battery type:18650 Rechargeable lithium battery

Your link offers 2 different sizes!
Spacifications:
Model : SC-DC3S and SC-DC6S
Capacity: 6000mAh and 12000mAh

The pictures are DIFFERENT to what they write in specs!!!
Picture only 19V@1A while spec says 19V@2A

I refered to specs while Colin Taylor refered to pictures ... the truth might be somewhere in between.
Or the smaller one will give you only 1A and the larger even 2A - who knows - its chinese!

 

[Val D.]

SC-DC6S is rated 12000mAh or 12Ah with a lithium battery which means about 3V.

Li-Ion cells are usually around 3.6V-4.2V depending on chemistry and charge levels, but the main problem is we can't trust Chinese no-name manufacturers about capacity. What is listed as 12000mAh may be way less than that as real capacity.

 

[ColinTaylor]

so what do you think the asus ac68u can work on 19V 1 A in this ups or not ?

As I have said more than once, I don't know. You are trying to run the router from something that can only supply 57% of the stated requirement. It might work, it might not.

 

[Val D.]

The specs say that it has a system voltage of 11.1v with is consistent with 3 18650 lithium batteries. So that's 11.1 x 12Ah = 133.3Wh

3 x 18650 in series gives you about 2200mAh (1800-2800 depending on cells used), or the maximum capacity of a single cell, just with higher voltage.
