Creating a kiosk

Especially if can do something like maintain the battery overnight, plugging it into a charger when haul it in from the beach)

Would not need solar then, nor would it work on the new 20 volt tablets.

Really it's the same as a car charger - and if there's a tablet that needs 20V, I'd expect before long there'd be a car charger to support it.

Exactly!
As enticing as it may seem to go directly into the computer, the expense of a car/airline charger that will work off between 10V and 18V is small compared to the risk of damage to the device from going direct.

The part that says it is a quote by SunKing is *part* of my post.

Mods - something has gone badly wrong with this website - you need to look into what happened that posts are getting corrupted.

Hello

I am looking at creating a solar kiosk to be used for charging up to 10 mobile phones.

I am very new to solar panels etc. so i was hoping you could assist me. I have the following questions:
If i use a solar panel with a peak power of 30W, would that be sufficient or should i get 2x 30W panels?
How would i connect a usb mobile phone charger to the solar panel?
Is there a chance that too much power will be generated and a phone battery might get damaged?

thank you in advance

I am not sure how portable your kiosk needs to be but I built a small solar battery system to be used when I was out in the field flying my RC planes. I have only used it a couple of times but it does the trick even though it cost almost $500.

It is basically an 80 watt solar panel (should have gone with a 100watt) with a small 10Amp PWM Charge controller. The 12volt battery is a Blue Top Optima 65Ah and a simple 200watt inverter. The hand cart is something I got from Harbor Freight and the battery box can be found on Amazon or Ebay.

It packs up to a small footprint and is easy to transport unless the ground is real sandy or muddy.
