Economic factors in upgrading batteries

but on sites it was tripping the power supply.

This confuses/surprises me
My aforementioned anker brick draws 1000w to recharge which is about 4.3amps, so most hook ups should cope.

 

[The Wino]

The Wino The fan is a Dyson hot+cool (£600 worth!). We bought it for our daughter when she discovered she has Crohn’s disease - a side effect is that she cannot easily regulate her body temperature, but she found it too noisy. The fan is rated at 2000w but we read that, at the minimum cool setting it draws 1000w. We found this ideal for cooling the motorhome at 30 degrees plus outside temperatures but on sites it was tripping the power supply.

I was trying to understand the physics! Unless there's an outdoor and indoor unit like Aircon I can't see how it would cool the inside of a MH. There would be a cooling effect on skin due to evaporation of moisture ( sweat!) but if it draws 800w it's going to be a pretty effective heater!

The Wino A good question. I just looked it up on “how things work”. It doesn’t actually cool the air, it makes it seem like it is cooler due to the smoother air flow. That sounds like a mixture of the Emperor’s new clothes and magic… However it certainly works. The same review said that our version mark1) is much noisier than mark 2 but is efficient. It drawers 1000w but the output is 800w.

Langtoftlad Yes, the first two times we used it the power stayed on. All I can think of is that where it tripped, even on the minimum setting, it initially used more power to get to the correct temperature.
