Has a 5 star review on Takealot, I wonder if the reviewer would still love the colour and the R20K he paid for a R6K unit.

R6K at Geewiz

It's probably the seller that is posting the review...

It's possible the review was for the same product at a different price, and possibly even a different seller.

Hi guys.
These Gizzu type UPS for Fibre box / Router have very short dual port output cables. Can one purchase an extension? I know it could probably be easily made but I need to buy a few and for other people and I'm not sure they will appreciate my hack jobs.

With the dual DC Gizzu you get 2 separate cables and they're much longer than the cable you get with the PoE model.

Edit: The cables are 1.2m each.

I have a question for those electrically gifted souls in this thread.

Looking at this Ellies cube Mini. It has the following stats:

Battery Type: 105Wh - 6 Cell Life Po4 (Lithium Ion Phosphate)
Min Battery Wh: 101 Wh
Battery mAh: 40 000 mAh

I'm trying to figure out how mAh relates to Wh.

This calculator shows that the above stats hold true if we are using 2.525V as the battery rating... but this device works at 5V/9V/12V. Why do the calculations hold up at 2.525V?

I don't really understand your question? when your voltage increases your current decreases for the same watts

10W = 5A x 2V
10W = 2A x 5V

You take the voltage of the batteries times the Ah will give you Wh.

AFAIK, lithium cells are 3.7V

3.7V x 40Ah = 148Wh

So the numbers don't add up I agree.

 

[Dylan_G]

10W = 5A x 2V
10W = 2A x 5V

If the device is 101Wh/40000mAH, why does the calculation only hold true at 2.525V? Doesn't the device operate at 5V/9V/12V? Why is the calc "only working" at 2.525V?

You have to look at the input voltage from the actual batteries.

The output voltage has nothing to do with capacity. It's just at higher voltages there is less current to equal the same wattage.

Ah okay.

From Wikipedia:



So it seems doing those calcs at 2.525V kinda makes sense.

Thanks guys.

Also, regarding the Cube Mini... Did we ever figure out if it truly is only 1A@12V? EDIT: Even the 9V port is only 500mA. Thats sad if true.

Been wondering about this too. Can't for a moment imagine that it's limited to 12W, but will be interesting to hear first hand experience.

No - I followed up with Ellies this morning, they just responded that they're waiting for reply from the supplier.

The question that is still outstanding is the max output of that Ellies / SunSynk thing. I can't for a moment believe the data sheet is correct at 12W, but am hesitant to recommend it until we have clarity

They responded to me on facebook that its 12w.... but still waiting for confirmation from the supplier. (I don't think its going to happen)

And the usb is only 1a too... Dont think my phone would even bother charging at that!

Thank you.
I have a bunch of other UPS that have a single output with a splitter but its only like 15cm long and the two devices have to be practically on top of each other.

But to answer your original question, Geewiz sell extension cables, I think it's R50 for 1.5m.

Dumb question.
I know its a 2.5mm port. All of the extensions are

DC Extension Cable for CCTV 12V Power (5.5mm x 2.5mm)​

Whats teh 5.5mm part? The female side?

 

[Glock26]

I have a Ratel 430m (never used) for R500 if anyone is interested.

Can't message you. I would like to take it. Can you message me?

It's usually indicated as outer radius x inner radius.

Just got two of these today for the same reason.

hi guys need advice on powering following items

• ASUS AC2900 RT AC86U (19V 1.75A)
• Fibre Box ONT (12V 1A)

i am confused on the router because on back it saying 19V 1.75A / 12V 3A so does it mean i can use it on a 12v?? will i lose features because of the drop in voltage? i cannot find any info any where. the power adapter it come with is 19v 1.75A 33w

the plan to power router and ONT for minimum 2 hours what solutions are available? would very much appreciate help for this loadshedding
