As per title, I'm looking for a prebuilt circuit of on of these, anyone know where I can get one in Cape Town?

Tiny I guess? I'm looking to step up the voltage from a Powerbank from 5V 10V to power a Wifi/switch at home during load shedding. I have the Fiber router sorted with it's powerbank.

You are looking for a DC boost converter. I had a look, but your input voltage of 5VDC is an issue and I do not see any cheap options.

Why do you not run a separate 12VDC LiIon battery to 10VDC via a DC-DC converter? Is going to be cheaper than a boost converter.

It is doable.

QC2 and QC3 chargers can put out 9V and 12V as well.

The easiest is to get a purpose built box with a battery, charger and box.

BWS, I ordered a few of these yesterday. They probably won’t get here during this round of loadshedding, but at least I should be ok for ‘next time’.

I’m ok for my network, since all my network kit is 5V devices. However, the landline has a Siemens Sender unit which requires 6.5V DC 600mA, hence this purchase. Although I have a few UPS units throughout the house, this particular phone point is not close to one so I think a little step-up buck unit should work fine on a powerbank.

That said, our Telkom exchange goes off-line as soon as loadshedding kicks in and does not come on by itself after power is restored. I have reported it several times and hopefully someone will listen and finally sort it out. Its a big pain as the technician normally sorts it out just before the next loadshedding turn and then its down again - and so it goes, with very little uptime. Just by the by, looks like most, if not all, Yealink DECT phone systems works off a very handy 5V, so I will probably buy one of there phone systems next time round.

Here is the link to the units that I ordered - they are pretty cheap and for some reason it would only let me select a max of 4 units to order:

Thanks Wolla, that's just what I'm looking for. You're full of solutions :ROFLMAO:  The Powerbank idea is yours as well

@Wolla , will you be using all that you're bringing in? If not I'll buy one from you if you're willing

Haha, yes if one is poor you have to think up cheap and practical solutions. I believe that every device that requires DC below 12V, should rather comply to the 5V standard - it just simplifies everything soooo much.

See if it will run off a 9v rechargeable battery.

I suspect it will, I'm going to step up to 10 from a Powerbank.

This works very well. I am using a Romoss 16,000 mAh 5V powerbank and its now powering both my cordless phone as well as wifi router during Eskom load shedding. This has now freed up a small trolley UPS/Inverter which I can now use to run all my lighting needs during load shedding.

This little adjustable buck Voltage converter made it all work out, as my cordless phone base station requires 6 Volts DC and not 5V DC.
