I am new to this forum, highly recommended by a friend and as they say a 76 year old technology retarded ou toppie so need good advise and help please.

Load shedding is getting me down so I need some advice to buy a UPS (battery backup) for my router and also DSTV if available, a combination would be perfect but not a requirement Also recommended suppliers please.

Router is Telkom d'link DSL-G2562DG and DTV decoder Explora Model 3A.

I have search aunty google and also looked at post in this forum but all is very confusing in selecting the best option/s.

Get one of these first and measure everything together for a few hours like you're simulating loadshedding, then we can say what your requirements are.

Digital Watt Meter (Kill A Watt) - Measure your electricity usage

Sorry I don't understand how this will help? I just need ups or battery backup thingies to powerup my router to access the internet and to powerup my explora to watch DSTV when power is off during load shedding.

You will need to know the amount of power your devices draw in order to find something with enough stored battery power to provide enough power to them for the expected period.

You could also look on the plugs of the devices and see the Voltage and Amp rating listed on them. But this is not as accurate as it normally shows the max draws.

Well you cant watch dstv on your explora so you need to run a tv too? Thats why they asking how much power you draw.
People cant help you if they don't know everything. Like what internet you have, is it fiber with an ONT etc.

To run your internet should be easy and relatively cheap. Xplora and a tv need way more power.

Edit: if you give the name and models of everything, maybe some good Samaritan will look up their power draw for you and you don't have to buy the meter.

Ok. So I struck out on the power requirements for the D-Link, but you could look on the back of the router. Usually labeled INPUT. Should be either 12V or 9V.
The power draw for the Explora is +/- 40W (12V3.3A). Could be less, but better to rather overspec.
What model TV do you have? The power draw is usually also stated on the back.

I just want to understand, that when you say DSTV decoder, I assume this means your TV also?

So in essence;
You want to power the following items:

WiFi / Internet
DSTV Decoder
TV

Correct?
 
Thank you for the help and advice. Best to forget about the explora/TV portion as that might get expensive and only looking at the wifi router. Internet is telkom ADSL line. router is Telkom d'link DSL-G2562DG
I will do some further research on the modem.

It will need 12V, from what I can see from the spec sheet and if the above looks somewhat accurate to your unit?

A Gizzu type of mini-UPS is your best bet. But you will also need to get an adaptor plug from your local electronics store, geewiz, or china shop as the gizzu comes with a standard 2.5mm plug, pictured below, while you will need a thinner one, similar to the one seen below.

But please do not pay R1500 for a gizzu, as they can still be had for sub R1k if you shop around. Also avoid the 'standard UPS' advice you will inevitably get ... unless you have one lying around?

Something like this would work.

So for 12V only this will work too.

I've posted this is a few threads, you can make with it what you will. ( Ie most people knock down the UPS approach because it isn't efficient, and yes that is true, but sometimes, it's irrelevant when you want an adorable solution that does the job. )

For the Wi-Fi portion, you have two options;

Get a DC UPS, like the Ellies Cube, Ultralan ( specifically this one; https://loadshedbuddy.co.za/product...poe-17w-8-8ah-dc-to-dc-lithium-ion-105wh-ups/ new stock coming next week hopefully.), or the Gizzu DC UPSes.

If you have an old UPS laying around somewhere or know of someone with one that they are not using, take that and add a Lithium battery to it and it will work perfectly for your Wi-Fi.

For the TV, you have two reasonable options;

An inveter trolley paires with at least a 100Ah battery.

Or...

Get a UPS and use a 50Ah lithium battery

I currently do this with a 100Ah battery ( 160 watt load ).

Works good, definitely a hack but still sound solution.

Then to work out what battery you will need, here is a post with some maths ( heavily inspired by some users on Mybroadband )

Thank you just looked at the normal power supply running from mains for the router so what I need as backup must fit output 12v 2a 9.0x5.5x2.1mm power supply
 
So many options to choose from at so many price points.
In the end it all depends on what you're willing to spend.

That's a standard plug so all good.

That's a great price for the UltraLan.
Think that's what I paid last year for mine.

5.5 x 2.1 is slightly thinner (on the inside) than the (what I call) standard 5.5 x 2.5mm plug on e.g. your gizzu - but I can be wrong, as some of them are quite interchangeable. Of course you will struggle if the center male pin is thicker.

You are absolutely right. Just had a look at my UltraLan. It does have the thicker centre pin. I always just assumed that it was 2.1mm.
 
Just get a trolley inverter (750W) with 1 or 2 100AH batteries.

A UPS is only designed to keep the power on long enough for a generator to be started or to safely shutdown a PC, not for long runtimes.
