Solar Power Banks

[Ric.ror]

I would like to buy a new power bank and would like to get a solar one this time
It’s to recharge my iPhone but we also now have clip on fans for the buggy so one to recharge that too
How will I know how many times it will recharge these items with one charge

I hope that makes sense

Divide the capacity of your iPhone battery by the capacity of the power bank. That's how many times it will recharge it. Do the same for your fans. Eh. iPhone 12 pro capacity is 2,815mAh. So a 20,000 mAh power bank will charge it roughly 7 times
