Hi folks.
I could really do with some advice in regards to portable power & charging options etc.
I enjoy a bit of camping & can be away 2or3 weeks at a time. I am trying to avoid electric hook ups as it can be restrictive. The only things i need power for is my Archos media player (which needs 6V 2amp) & a couple small lights in the tent.
So my latest idea is to buy a couple of 20ah sealed lead acid battery & rotate them over the duration of being away. These are a lot lighter & less bulky than the other options (leisure battery or powerpacks etc) & hopefully more versatile.
The problem i have is charging. When driving I need to be able to charge from my cigarette lighter of the car. I need a charger that will output as near to 10amp as possible without going over so the 20ah battery charging process takes approx 2-4 hours (i assume this is correct??)
The charger i'm looking at is the ring RSC16 smart charger Smart Charger - Portable Power > Smart Chargers > Smart Chargers Unfortunately this does not come with a cigarette lighter adaptor, so as i understand it, i will need an inverter.
The inverter i'm looking at is the Belkin Anywhere Power Inverter Belkin Anywhere Power Inverter 140W F5C412UK140W - PC World Business Online Store UK - Buy The Best Deals Online. This comes in two power sizes. Smaller provides 140w & bigger one provides 300w.
According to car handbook, my cigarette lighter is limited to 10amp output so i'm assuming anymore than that will either blow the cigarette lighter or the car fuse.
Can anyone tell me what 140w or 300w relates to in terms of Amp per hour ?? .... I'de like to get to as near as 10amp as possible without going over as i assume a 20ah batter should charge between 2&3 hours with the ring smart charger.
Can anyone also tell me if my plan is completely flawed & i'm missing something ??
