Router Battery Backup

[joker08]

I'm thinking of picking up one of these.

where are u getting those from ?? can u give a price estimate and maybe a link to buy one

The last round of load shedding some co-workers bought it for their routers. I'm just worried about the battery discharging completely.

isnt the charger suppose to manage the battery drain and prevent it from over draining.

I use a Netis DL4323U with a 5V 12000mAh powerbank. It lasts about 10 hours on the powerbank.

Before the Post Office went completely tits up I ordered this cheapie 5v USB to 12v 5.5mm dc jack converter cable for R25, seemed to be rated for 12 1A output if I recall correctly.

Tested it the other day plugged into a USB battery bank on a Huawei ADSL WiFi router, worked perfectly, 2 devices connected via WiFi. The router has a 12v power supply rated for 1.5A, I'm assuming if you only use the lan the power use will be less but something with high powered AC WiFi may use more.

i wonder if it'll work

It's overpriced as the battery is not included. You can buy a 850VA UPS from Takealot that has a 9 aH battery and a port for a multiplug so u can charge 2 devices, for cheaper

How many amps do your modem/router need? If 12v at 1.5a then they router will at maximum (ie, not typical) draw 18w of power. A 5v 2a powerbank can supply 10w continuous. Modern devices contain switch mode power supplies which include a boost converter - it will convert the 5v 2a to 12v 0.833a (to maintain the powerbank's ability at 10w).

The short answer is it will work, but the moment you start drawing more than 0.833a (don't forget about losses!) the router will reboot. So you will be able to use just under half of the router's features

The takealot 5v to 12v booster is exactly what I have used with a router that needed a 12v 1.5A power supply, worked fine via WiFi.

Use an old Mean Well AD-55 51W with a 12ah battery. Last the loadshedding, through. Both my Mi Router and my Mikrotik wifi router outside running on it.

A ups is the best option, but I don't like the fact that the Inverter will be converting current from a 12v battery to 220ac current then my power brick will convert that current to a 12v DC .
The fiber modem is 12v and router is 9v. Finding batteries of these capacities is easy.
All I think we need is a intelligent charging solution that will charge the batteries and supply a constant output.
May be I will give mantech a visit may be they can help, could have checked their website but its is too confusing.

just checked their website, too expensive. I got the charging circuit for a samsung S7 from local mobile shop for R80, why should a lead acid battery charger be so expensive.
I think in sometime, importers will look at this load shedding thing as a business opportunity and start importing stuff which will drive the prices down eventually.

Where do you see that it is 5v to 12v?

I wish I can find this locally

USB 5v to 12v, see the pic below

I also got a 5v to 9v on ebay, they will probably also have those on Takealot, see the link in an earlier post for the 12v version.

I'm saying that the Takealot link makes no mention of 5v to 12v so it is probably not the same thing.

is that Meanwell a power supply or a battery charger?

Have you tried ZakSpeed? They will make one for you as you wait in store.

Both and more , power supply, with switching capabilities.
