USB step up module problems?
I made a power bank with 2 5v solar panels connected to a 18650 charger and from the charger to the battery from the battery to the switch to the usb .9v-5v step up module. It only maxes out at around .5 Amps and I just realized that. Everything works and I can charge small batteries but when I try and charge my iPhone 7+ it trickle charges and won't show the charging animation. I herd iPhone charge at 5v-1 amp so is there anyway I could make it work with my iPhone.
I'm using one 18650
The current is limited to what the solar panels can deliver.
If you want more current and therefore faster charging,
you will need more solar panels connected in parallel.
