when requested by the device?
(For instance, my android phone will pull 2A when allowed by the device.)
G'day Kando,
Sorry mate, no idea.
I have no intention of reading the entire manual to find out (non fiction is as boring as bat pooh).
Much rather be reading Lee Child, James Lee Burke or similar
I asked in forums for a a fit and "forget" solution to keeping my Edge 800 charged as well as my phone and headlamp torch (Petzl Tikka 2 XP) and the Son28 with E-werk with cache battery was the most common reply from people I knew who actually toured and not simply posted opinions in forums.
I simply don't care enough to learn how it works.
It does and thats good enough for me.
I was so impressed I bought a second system the same for my trailer. (The same bar a different bigger cache battery)
I put my phone in airplane mode or off, except when I'm actually using it for something, in an attempt to use as little power as possible.
When I leave home everything is charged.
It takes some hours of riding to put some serious charge into the phone when empty but not as much for the Edge or Petzl.
Thinking ahead helps me keep on top of it easily enough.
The genuine Ewerk cache battery has a pretty small 1400 mAh as its purpose is really to act as a buffer
