Yes, the Kickr II is compatible with the Samsung Galaxy series.

This message can appear when the voltage from the solar panel drops below Apple's approved threshold, such as when a cloud passes over the solar panel. To resolve this, simply unplug the panel, return it to full sunlight, and replug in the panel.To get the best performance out of your Kickr, always use the panel in direct sunlight (not through a window), ensure no shade covers any portion of the panel, and keep the panel angled toward the sun.

If your phone can accept power via USB, then it can be powered by the Kickr series! You can use the included USB to Micro USB cable or the USB cable which came with your phone when it was purchased to plug directly into the Kickr.

The Kickr II is only able to put out a maximum of 0.6 amps, assuming strong, uninterrupted sunlight. Apple iPhones require a minimum of 1 amp input before it will recognize it as a power source (non-Apple devices typically do not have such requirements). We recommend using one of our Jumpr Slates to store the power gathered from your Kickr II, then using that Jumpr to power your iPhone when you need it.Our Kickr IV is able to put out a max of 1.2 amps (assuming strong, uninterrupted sunlight), so this product may better suit your needs.

We would describe the Kickrs as water resistant. These panels and the USB ports have been waterproofed, so they can be submerged in water, however we can not guarantee the products you plug in will be protected. If your Kickr does get wet, please let it dry before plugging in any devices.Kickr IIs cannot be folded. We recommend the Kickr IV if you need a smaller storage size.

The Kickr II - under direct sunlight - charges your small devices at 1/2 the rate of an outlet. For example - if it takes your iPhone 5/5s phone to charge via a wall outlet about 1.5 hours - it will take the Kickr II twice that amount - so for this example 3 hours.Charging times per phone vary due to what you are running, what apps are consuming power, and if you are currently using the device in anyway during charging.

All of our Kickr's and Packrs have a full USB port that allows for USB enabled devices/cords to be charged with the Kickr/Packr.For your specific phones - you will use your lightning connector - simply plug it into the USB port and you are good to go!
