Reviews says it's a 5v cable.

Looking at the cable I do not see how it can magically outputs 12 volts without any additional electronics.
So confused

Less loadshedding, lower price. If someone is interested, Gizzu R799. Think it was way north of R1100 in the mids of loadshedidng.

Powers both my mesh router and fibre ONT - can get about 6-8 hours depending on how many devices are actively trying to watch the entire youtube

How long do these units last for .. not in hours saying like 2 years ? 5 years ?

Should last over 2 years. I got one that's about 3 years old and still going (similar unit).

Depends on the load you put on them and the recharge cycles.

That’s a bit of a rip considering it’s double the price of the smaller units but you only 65Wh vs 45Wh of the cheaper ones.

Most of them use 18650 lithium ion cells so they should last near an eternity, 5yrs easy and even up to 10Yrs depending on the cell quality.
Also it’s very easy to replace the cells if needs be and it just occurred to me now you can even increase the capacity by adding more cells.

If changing the capacity of the batts, consider the fact that the BMS has to be instructed of this new capacity.

So for the layman, a replacement of batts with higher quality cells like 30Qs might be the best bet as long as you're able to attached the wires to the batts without damaging/overheating the cell.

BMS's work on voltages not capacity.
