n0, a small solar charger is still just a SMALL CHARGER and that's going to take forever to charge larger things.
If you have a phone, you buy a spare battery or two to take with you. Swap 'em when you need to. If you're cursed with an iPhone, you buy an external battery, recharge it, it plugs in to rejuice the phone. (Works for other phones, too.)
But solar chargers? Buy the biggest, least convenient, most expensive panels you can get, and things will charge faster. That's just the way it is for now.
