I bought this solar charger last week. It was an Amazon Lightning Deal. https://www.amazon.com/gp/product/B00YOP7LV8/?tag=survivalmonke-20 The deal was a solar charger for $14.95. I thought why not. It is a small charger that came with a clip so I could hook it to my backpack. When it arrived, it looked like the box had already been opened but I decided to try it out. The charger came half-way charged and I hooked my phone to it. My phone went up 10% before the charger was out of juice. Since then I have been unable to get the unit charged past the first bar. I have had it out in full sun for 2 days and nothing. I checked to make sure the light was not on. I am declaring the Dizaul Solar Charger to be junk. I will be sending it back. The regular price is $23.95. I like the compact size but this is garbage. Since the package looked like this was a returned item, I think someone else found out it was not worth spending money on also. Solar charger #2 I bought this portable in February. It was under $30 and is no longer offered on Amazon. The closest to it is this one by the same manufacturer. https://www.amazon.com/dp/B07FPHHNDL/?tag=survivalmonke-20 This solar panels charger is great. I love how it folds up to the size of a thick cell phone. The light is bright and big enough to actually act like a flashlight. It does take sometime to charge the battery but I threw it out on the lawn and it was at 3 bars after about 5 hours of full sun. Please note: this is an emergency cell phone charger, that is what I call it. Do not expect something like this to charge your dead cell phone 100% quickly. It will not. This is for giving your phone a small/half charge so you can make calls. It may have more of a capability but to-date the boys and I have just used it for a quick charge when we are not near power. I have a power pack that I use for full charges when out and about. For the price I paid, I am happy. It does what I wanted which was to be an emergency solar panel to charge phones. It is light and compact. This can be hooked to your backpack and be charged while hiking. I used to keep it in my car for just in case but the kid commandeered it and been happy with the unit.
