Recently added products on the internet gives Goal Pro a Run for the money. This is all about what to take when Backpacking so I will relate this as best as I can. The physical collector or panel has gone thru many changes over the years. What you could buy a few years ago, is easily trumped by better quality products. The power gets better, as collection lines get thinner and tighter together according to the innovators over in Japan. Goal Zero & Joos are dominating the market and at the same time are pricier than the rest. but here is the rub - Almost all of them have to have a perfect day to work 100% On the other hand you can flip a Goal Zero backwards to the sun and still get some charge. The only time these larger panels don't work is when you are getting rained on. - Leaves scatter the light, so its 50% nowadays and some charge is better than nothing. Look at the size difference, most of the working panels are 8"x10" or larger. One only has to see something smaller like the size of a DVD and read the complaints on Amazon... The Smaller ones like Solio are budget wasters. There are also a load of knock offs, that appear cheap & lack power management and protection diodes and after a season are broke.
Flex film require far more panels to collect the same amount of power, recently there was a Bear Gryls version, a quite a few complaints. It doesn't mean it doesn't work - but if you remember Bruton was twice as big for a reason, and a hefty price too.
Measuring circuits ( a series of resistors and chip) on the Motorola Android, Apple Iphone, and Samsung will prevent you from direct charging a smart phone on most solar chargers, the circuit or short on data wire tells the phone you are not using the proprietary charger that came with it...* You charge directly to a battery backup or a older phone and later send the power into the Smart Phone. I will order and test the Anker to see if they solved this.
Enter in a new candidate. Anker 14 Watt 1 Amp per 5volt port 2 amp total gives Goal Pro a boot to the side on price and amount of panels, Charge two Items at the same time!
Keep in mind the trail doesn't require 14 watt as many products have regulators and circuits that prohibit battery fires or overcharging... most equipment can work properly with 5 watts on the trail.
