Which UPS would you recommend

the mecer UPS has tiny batteries and is inefficient you'd rather use DC-DC like the Ratel or 5v battery bank booster for DC devices and keep the UPS for AC devices like a PC/laptop or similar

Exactly what I did ... 850VA Mecer UPS for my son's PC, and two Ratels to keep connectivity up. One for the ONT and Router in the Study, and one for the Wireless AP in the lounge

For what's it is worth, I got this extra just to run my ONT +fiber router. Seems to do ok with yesterday's 2.5 hour shed

At that price I'd try and find a Ratel rather, to be quite honest
 
Does anyone know if you get software for the Ratels, like you would for normal UPS units?
I see the specsheet says "USB Interface", but for what?

How do the two compare? The Ratel has more and bigger batteries so lasts much longer doing exactly the same thing?

The 860P Ratel has 60w total output, and has 5A on the 12V ports. The other device only does 1A.

Also, the Ratel has PoE and solar charging.

Edit: There are three Ratel models, that device from Takealot is similar in spec to the smallest Ratel (412). Unfortunately there is no stock available, but even the middle Ratel (430) is much cheaper (and far better spec).

60w on the Ratel vs "Capacity: 38.48Wh" on the Vizia one?

Is 2A vs 1A as simple as the rating of cell phone chargers, for example? So, basically twice as fast / powerful?

I should have prefaced my previous questions with some #electricitynoob warnings probably...

The Ratel 860P has 8 x 2200mAh @ 3.7V for 65Wh. The Amperage is the amount of current the port can output, but is also dependent on the spec of the device being powered. A device requiring more than 12W will not be able to draw enough power from 12V @ 1A.

Remember the formula: Watts (W) = Voltage (V) x Amps (A).

Ok, thank you.

Seems as if the Ratel 860p is certainly the way to go for a simple plug n play solution to keep a few devices going through loadshedding (like fibre ONT and a router).

If it is only those two devices, you could go for the 430P. It is a lot cheaper, but should still have more than enough juice for those two devices. ONT and router I'm guessing are about 15W combined. The 430P does 30W, so you're safe on that side and has 32Wh, so should run both for more than 2 hours.

https://www.communica.co.za/products/ratel-430p Nice!

Only R820 (but currently sold out).

I've never even heard of this Communica place before now.

Nice!

I'm sure you can guess my next question... Any material difference between the two? I can't tell from the stats listed...

I think my edit was just too slow. Difference between the P and M is that the P has Power over ethernet, and the M not.

Thanks. Hopefully my questions (and your answers) can also help others who read this thread.

I had to Google PoE: Power over Ethernet, or PoE, describes any of several standard or ad hoc systems that pass electric power along with data on twisted pair Ethernet cabling. This allows a single cable to provide both data connection and electric power to devices such as wireless access points, IP cameras, and VoIP phones
