there is no amount of sunlight that will charge this on solar power alone. it works great as a portable power bank, but do not expect to have it recharge during the day once you’ve depleted it.
works great and has strong power to charge but eesh it’s heavy. not really practical for backpack or bag. not bad for keeping in a camper or car i guess. defeats the purpose of portable power.
