Quick question - how do I power three devices off the Gizzu - do you get a three way splitter?

What about 2 x two-way splitters?

(although 1A USB is basically useless, no?)

PS - no your @14.8V is wrong - as it says on the link - 38.48Wh - so it must be 3.7V (typical Lithium individual cell voltage)
Click to expand...

I would regard USB @ 1A to be 'useless' yes, but that info could be completely wrong - might be that the seller is understating the specs etc. Once again I would expect the unit to at least put out 2A, even at 12V.

Re: 14.8V
Yes, the individual cells are 3.7v, but I suspect that they are connected in series, giving you 14.8v - the gizzu for example has a sticker on the bottom confirming the same - 14.8v 2200mah.

Not finding stock... and wth load shedding at stage 4 - my billable hours is becoming an issue ...

I need to get to the plugs to see what all the devices are rated at - eveything is currently behind our firewood stack :/

Not a problem to just splice the cables together - i.e. cut the wire off your current 'wallwort' (or an old one in the man drawer that fits) and splice it in (just check the polarity first) - if some of the words above don't make sense, then possibly, don't do it :)

I want to power a USG, the fibre box, and a Tenda Wireless extender.

Fibre box and a simple Tender Wireless extender - likely to be quite low power (<10W each, likely to be well below rated power 90% of the time)
I don't know what a USG is...

The Link says 10400mAh and 38.48Wh... ? We can all do different amp hours if we want :)
24V * 1.6Ah = 38.48 or 5v x 7.7Ah = 38.48Wh?--> not sure what your point is?
Click to expand...
My point is that his guess of 14.8V output is probably correct. The 14.8V is made up of 4 * 3.7V cells in series.
 
Just a question regarding splicing of wires. The one I want to splice doesn't have any red or black wire. Can I assume the wire with the solid white marking on it is positive?

Was thinking of doing exactly that...

All makes sense - and I have a few lying around... will first try and find "ready-made" versions.

RE: USG = Ubiquiti Gateway - its rated as max 7w

I could use the extender alone with the fibre box, but it'd mean switching out the lan cable with loadshedding - and the entire setup is behind a bookshelf packed with wood.

At the moment, the plan is to connect the Tenda Wireless extender to the second port on the USG - and only use it when there's loadshedding. (I have Ubiquiti APs in the house, but - not really in the mood to try and power the entire network)

I run an edgerouterX and ubiquity AP lite via 24 volt POE and a Huawei ONT via the 12 volt outlet. After 2.5 hours loadshitting, the power lights show that there is between 25% and 50% power left. The box recharges to 100% within about an hour.

I would think that your setup would use a similar amount of power, if the 12 volt outlet can accommodate the power drain.

Worst case, I can somehow run the cabling so I can easily switch the ethernet cable from the fibre box and remove the USG from the equation.

Noticed the Tenda POS is 9v while everything else is 12v, I have an Asus router which is 12v at 18w max... And then another router somewhere which may be less... Will have to find it. Literally need it as a wireless AP only.

Easiest way to reduce the voltage for the one unit is to wire 4 1N4007 or 1N4001 diodes in series to that unit. That will reduce voltage by about 2.8V.
 
Deleted. Picked up great advice in later posts, so this may not be an option.

I was just thinking about All these mini ups although more efficient as its direct 12V compared to using a regular UPS(and the internal timer of a ups but i found some that can be disabled or do not come with that) - but what about after a year or 2 when the battery needs replacement?
any idea if you can replace these yourself?
regular UPS is easy and can even put larger batteries

Lithium battery should give about 500 cycles. If you're using one or two cycles a week that should last a good many years.

Think they're standard 18650 cells so could DIY. Think they'll last longer though as they're lithium.

I bought a 430M and disassembled it. I see the cells they use are 0817's so I'm adding another bank of them. I take back what I said; they're more than just a few off the shelf parts. Very good value for money, and easy battery change without a warranty sticker being voided.

I'm thinking 2 more banks of four cells each since cells are like R79 + enclosure R30

Hi

I am trying to get my hands on a Ratel 860p but I am concerned about the connector cables.

How would I know what size the pins on the included Y cable are?

I have a Tenda AC-10U router and a Calix Gigapoint 803Gv2 ONT.
The manuals do not have the pin size, how can I find this out?
 
i had to get an adapter for my ONT from geewiz.
by the way i am very likely to sell my ratel (1 month old), as i am getting the RTC powerbank.

Thanks

I was wondering if these pins had a name or dimension so I can order online
