Just took delivery of one of these and thought I would just put it out there in case anyone else has an interest.
Basically it is a 90,000 mha power bank with loads of outputs usb and usb c an 12v. Doesn't pretend to be a power station, no AC outlets and is basically capable of charging all your devices up while you are away. It feels extremely solid and well made, has a app of course, however, on board screen tells you all you need to know.
With the right equipment it can be recharged very quickly and of course it will charge your devices at their maximum speed.
I have 5 usb and 1 usb c in the van so didn't really need it, just wanted it, although I will use it in the van as I can charge everything in one location as opposed to be scattered around the van as present.
Anyway that's it really, know a lot of you do not like power banks or power stations so just in case anyone has an interest or questions
 
Looks excellent for what it is. There are two versions, one with a couple of AC sockets, and this one with just DC sockets (USB C, USB and Car socket). Very powerful, will power two laptops at the same time. Fast charging via double USB-C cables and fast charger.
 
288Wh equates to 24Ah at 12V (288/12=24). I can’t get my head round what the 90,000mAh means.
Usually motorhomers are talking about 12V batteries, so comparing the charge capacity in amp-hours makes sense. A 200Ah 12V battery has an energy capacity of 200Ah x 12V = 2400Wh. So it's twice the charge capacity and twice the energy capacity of a 100Ah 12V battery (100Ah x 12V - 1200Wh). Amp-hours x Volts = Watt-hours.

But if it's not a 12V battery, then the amp-hour ratings aren't a good comparison. Better to find the energy capacity in watt-hours, which is always a fair way to compare batteries.

If you know the energy capacity in watt-hours, you can compare it to a 12V battery by dividing by 12V. So a 288Wh battery is equivalent to a 12V battery with an Ah charge capacity of 288/12 = 24Ah. '12 Volts' means 12Wh per Ah.

The 90,000mAh rating for a 288Wh battery means its voltage is 288/90 = 3.2V, a typical voltage for a lithium battery.

That is the bit I was struggling to get my head round, thanks. It now makes sense though I am not sure the 90,000 figure has great relevance to most purchasers without a stated voltage.

90,000 sounds way better than 90 to the unsuspecting buyer. That alone would stop me buying one :mad: - plus I already have 210,000mAh in my van :ROFLMAO:
