Thanx to all for your input
After looking at all the specs of the various devices
1000ma = Go Pro
1000ma = Delorme
1000ma = IPhone
So I decided to go with 1000ma chargers
One 12 volt 1000ma car type charger
One dual voltage 1000ma wall charger
As far as energy budget
on the boat, I don't plan on charging every device
every day. The only thing that I plan on keeping topped off
Is the Delorme In Reach. I like to be able to communicate with my
without relying on any other on board device. I've tested its battery
duration and can get about 72 hours with tracking set at 4 hours and
5 or 6 text messages a day, this runs the unit down to about 20%
I'm also looking about for a charger that I can slip in some double A's
And give the unit a boost if all other systems go south.
If anybody knows of such a box I'd appreciate a link.
It is also my understanding that if I go with 2.1a chargers I wouldn't
harm the devices but they would charge much faster. Is this correct?
Thanx to all again
