Hi not really looking at forking out 5k+ on inverter solution for a few common household devices(kettle, TV, etc) at this stage, can someone recommend a economical alternative , i.e power bank, battery, etc

It would need to be able to supply 2aH for say 4 hours.
The router draws 24W according to spec sheet.

As an aside:
I have a 10,000mah Rosmoss power bank which comes in handy to recharge my phone..

Where can I purchase a suitable step up cable without making my own to power my router directly from the power bank?

Thanks, but as I already have a 10,000mah ( it can supply 2000mah) I just need a suitable usb 5v 12v DC cable.

Theres's those small huawei batteries but those are only good for about 3hrs. I have one and works a charm as I am able to continue working on the web without skipping a beat even after loadshedding hits - Like it did today. Just know that you are looking at around 3hrs and not 4. Should there be another option or alternative I am all ears.
 
Check this thread.

Anyone using anyone of these two to backup ADSL router during power outages? If so, any feedback or other relatively cheap solutions? https://www.geewiz.co.za/ups/80323-linkqnet-epower-12v-25w-dc-ups-for-d-link-routers.html OR...

Not with Rain when I bought it last year, but thanks.

I think I'll just try to source a compatible cable for my power bank to router( I mentioned I already have one).
 
Something like this might work. These devices can usually only supply ~1A @9V from a 2.1A powerbank port. Most 5V powerbanks can only supply a maximum of 10W.

I am using one of the Huawei battery packs that I bought from oceanmasterza a few months ago. They output 7.4V @ 2A.

Let us know should you get something -
 
@Jake45 You make a good point about the power bank likely only being able to supply 10W/hr, although the data sheet quotes 2.1Ah current output :giggle:

Confirmation: Seems I am in luck.It has 2 usb output ports, one of which is rated 1A and the other 2.1A :thumbsup: IMG_20191206_174635.jpgIMG_20191206_175100.jpg

@MirageF1: If you operate the router at between 7.5~9V then it should draw less current than at 12V. Neither the B315 or the B618 will operate directly from a powerbank as I have already tried to use them at 5V. They both work on the Huawei battery pack that I mentioned which outputs 7.4V.

If you don't want to order something from China then you could purchase a boost converter board from Mantech but you would have to wire it up and put it in a case etc. I think those ready made converters from China are probably using the same board internally as the same company also sells the separate boards.
