why are these modules so expensive and do we really need 2/4A ?
compared e.g. to this one
don’t compare appels to oranges … if you need 2A or 4A ? I don’t know…
* use case example : running an RPI + screen mobile on one 18650
For powering up nodes:
5v - 1000 mA … how’s that 10 W (ordered it anyway)
Yeahh, the 10W are overly optimistic, but as far as I’ve seen on some videos it charges at around 1.22A with “full” sun: so more like 5W/7W.
need a BIG cheap lcd display ?
