Router Battery Backup

That's not good, I specially bought a mini pc with no fan because unless the fan is barely spinning they become noisy and even more so as the device ages, 10W is hardly much of a draw. What does the fan cool, the buck/boost converters?
10W would be quite low for the fan to come on.

You could always add a speed controller and dial it way down, or completely disconnect it if you don't plan to draw more than ~30W consistently.
 
Sorry guys correction on the fan :X3:. Tested it now on a 50w load the fan stays off until the long heatsink heats up eventually.

That 10w load is nonsense heatsink was probably on the limit back then when i tested it since i heated up mine with the solder station before i did other stuff.
 
Also found and ordered the Elecstore Mercury at R429. Great price for what is promised.

However, the unit I received has a broken warranty seal. It's a very clean cut and barely visible. Looks like it's either very intentional, or very unintentional.

Anyone here who received one recently? What does the warranty seal look like on yours?

Not sure how good the warranty even is, but I guess I'll have to send the thing back.

Just checked my warranty sticker, it's not broken, but it is under pressure from the two panels over which it spans. I suspect the seals break by themselves on most units.
 
Has anyone managed to test the USB-C on these units?

I charged my OnePlus 12 for a couple of minutes from the Elecstor's USB-C port. It charged at 12 Watt according to the Elecstor's display, and at 10 watt according to my inline USB wattage measurement thingy. There is no difference between the power delivered by the USB-A ports and the USB-C port.

My MacBook Pro won't recognise power from the Elecstor's USB-C port though.

I picked up the Elecstor Mercury Edition 100W 75WH LiFePO4 Mini UPS today.

It's on sale for R429 @ Takealot.

Link:
This should be below cost, surely? It's a steal. The black version goes for R999 @ Takealot. The same one goes for R1 436 @ Geewiz. These were prices above R1600 in when loadshedding was still a daily occurrence.

This is still on sale at the same discounted price. The seller is clearly trying to offload stock. I suspect simply because batteries can't be sitting idle till the end of time. I'm happy I got one unit at this price, and only wish I didn't have to spend R1.6k for a similar unit at the height of loadshedding a couple of years ago.

Price is back up to R1789. That was a bargain!

Same paid a grand cost for mine now they selling for like R380 or something.

prob written off stock like the others.

Many options though which is great.

How is yours holding up since that long ago assuming you talking about 2023.
 
For those who want a refresher on volts, amps and ohms:

That said anyone know where you can buy the replacement battery packs for these things? They all use the same battery pack.

Try them they have a lot of different battery packs available.
 
Considering how heavily marked down they are new isn't cheaper to replace it outright?

Just replace the cells with LG HG2 3000mah/Samsumg 30Q 3000mah @ R89 each. I would not buy no name/Andowl/ZYF from electroman or like @airborne has stated replace unit.

Well I guess you can just buy new units each time but the battery packs in them are still pretty bad. Buying these replacement LG or Samsung might be worth it.

Cell's from "dead" laptop battery packs are always high quality, before opening them just make sure they use 18650 cells and not lipo pouches.

Yeah all these units have the cheapie cells in it. I buy from Potensa if I need lots of batteries but for the odd ones I just buy from Bossvape.

I just did that and they measured about 250-300 mA each (from 1800-2000 new). Even with 6 of them I can't think of a use for 6 Wh of capacity in 18650 form...
