   Great Solar Charger!!
   This solar charger has been fantastic for camping trips and outdoor adventures. It’s easy to use, compact, and lightweight, which makes it perfect for stashing in a backpack. The three USB ports are a great feature, allowing me to charge multiple devices at once, and the smart charge technology is really handy for optimizing the charging speed based on the device.The solar conversion rate is impressive, and it holds up well even in less-than-ideal conditions like light rain or fog, thanks to the protective PET polymer surface. The rubber covers on the USB ports are also a nice touch, keeping out dust and water.The only minor issue I’ve had is that, occasionally, I need to unplug and plug my device back in if the charging slows down, but this is rare and easy to fix. Overall, this solar charger has been reliable and a great addition to my camping gear. I’d definitely recommend it for anyone looking for a portable power solution for outdoor trips or emergencies.

   It works well!
   I received my solar panel last night and i’m currently putting it to the test. @ exactly 9:49am, i hooked up my completely dead OnePlus 7 Pro (4,000mAh) (that i don’t use anymore) to the solar panel. As of 10:30am the phone battery is at 16% which btw is really, really good given the lack of direct sunlight due to the cloud covers skies. To give you a better idea of how cloudy it is, i can look directly(or indirectly?😅) at the sun without going blind; Well, kind of. Also, I think if i were to charge my iPhone, it would be at ~20% charge since it has a slightly smaller battery (~3687 mAh). I bought this solar panel for the purpose of using it at a camping festival i’m going to in 2 weeks. Needless to say, this will suffice! I’ll update this review as i test it over the next few weeks @ different times of day.Edit: Friday December 22, 2023 2311I took this solar panel to Lost Lands (camping music festival) and it came in so clutch! I brought 3 power banks just in case (10k mah, 20k mah, and 30k mah), but with the solar panel, I only had to use the 10k mah powerbank. I would use the 10k mah throughout the day/night (7am-3am) and then I would set up my solar panel on my tent and hook the power bank up. That way, by the time the sun came up, it would be charging and be ready to be used by noon. The festival was from Tuesday-Sunday. The solar panel was charging very efficiently and very quickly (in my opinion). On nights when I didn’t set up my solar panel before going to sleep, I would wake up early in the morning to set my solar panel up and hook my powerbank to it, then I’d head down to the showers and by the time I got back it was fully charged. (Shower lines were long so I’d be gone for roughly 1hr-2hrs). Also, there would be times when it’d get a little cloudy but, the solar panel still charged pretty well. Though, not as fast. Overall, super useful solar panel. Totally worth it for the price.

   It is decent.
   I used this to recharge my phone. It works well if in direct sunlight. But takes longer than electricity to recharge a phone. If it is in a shaded location then the recharge is less effective.

   Kept my electronics charged for weeks
   I bought this for my hike along the Colorado Trail. I only went into town once in 3+ weeks. This kept my external battery charged the entire trip. Then I charged my phone and watch from my battery.It rained everyday day except for three. Generally I would attach this to the back of my backpack. During the day, it would get enough Sun to get a decent charge. It was never a 100% full charge. But enough to keep my battery well over the 50% mark. I’d say most the time my battery would drain to around 20% and recharge to around 85%. I had the best charging experience when at rest. I’d just lay this out if the ground, facing the Sun, and it seemed to charge pretty fast.The worst thing about these solar panels is the compartment where you connect the battery or your peripherals. It’s held closed by only a small piece of Velcro. It basically doesn’t work. Anything you put in that pocket to charge will fall out.For me it wasn’t a big deal. After having my battery fall out routinely and daily, it just fell out of the pocket from the solar panel, and into my large external center pocket on my backpack. From that point forward, I would never use the pocket this solar panel comes with. I would just put my battery in my packs external pocket, and run a cable to the solar panel to charge it. Problem solved. But definitely something to be aware of.

   Works great to charge small items like phones
   This solar panel charger was needed immediately when I ordered it due to hurricane Helene. I didn’t have an item I could have used during a necessary time of emergency outages in the state. Unfortunately the delivery date AFTER I purchased was 4 days away! Not the normal 2! BUT it STILL didn’t arrive for a month. This delay in delivery has nothing to do with the actual product but everything to do with the post process and Amazon. I did get everything taken care of through customer service in the end.

   It works!
   Based on my measurements, I have found that when the panels are directly facing the sun at an angle of almost 90 degrees, they can provide a peak output of 8.65 watts at sunny day.In practical use, the panels may not always be facing the sun directly. On a sunny day, when the panels are in a stationary position, I typically receive an output of 3-7 watts, depend on where the sun is and how intense it is. Such output is sufficient to charge my phone and power bank. Although it may not be as fast as charging from a wall outlet with fast charging capabilities, it is still a great source of free energy.I was pleasantly surprised by the performance of this small and lightweight panel. However, it is important to note that when the angle is low, such as 20 degrees, the output drops significantly to around 1 to 2 watts. This also applies when the panel is placed behind a glass window. Some of my power banks do not charge at this low wattage. The panel works best when there is only air between it and the sun.Overall, I am satisfied with this product.

   I received the panel on Sunday. found not charging any devices which I have ex. phone, pad, LED flashlight, and energy bank on sunny day. I gave up this device and returned it on Wednesday.

   I recently went on a two week remote fly-in kayaking trip and needed to get a solar charger for various devices. Of course, it’s always a trade off between function, cost and weight. This showed up on gearlabs webpage as the “best choice” and after reading reviews for awhile I gave it a go. Unfortunately, as you can see, there was significant smoke cover for most of our trip, as such it became clear it charges small devices very quickly in the light (iphone, watch, petzyl headlamp battery, most importantly garmin inreach), fairly quickly in the shade. But it had a hard time charging my bose waterproof speaker and the battery packs I brought with. But given the smoke, they would probably have taken a fair bit less time in full light (8-10hr for full charge in smoke). But we had occasional rest days and pulled out the charger at every paddling break and meal so we could make sure our emergency devices were charged. I hadn’t read fully about the waterproofing at the attachment sites so I didn’t test it while paddling or in the rain (see my drytop wrapped around the attachment ports when expecting rain). My paddling partner brought in a smaller device that wasn’t as fast with charging, did have multiple attachments but the cables were fixed so you couldn’t have two micros or two USB C at the same time (whereas this has 3 USB ports for any combination of attachments). Overall, I love this charger. It’s weightier than I’d like on a backpacking trip but for long distance outdoor events when you’re bringing bigger volumes, this is at the top of my pile. And I’m looking forward to using it in skies that aren’t under smoke weather warnings and evacuations….

    Estoy encantado con este producto, es muy facil de doblar y se puede guardar en pequenos espacios, pero lo mas importante es que de hecho es muy eficiente en carga y funciona muy bien, ayer carge dos celulares a la vez que estaban en 50% y tardo como 3 horas y ambas ya estaban al 100%, es un buen producto para aprovechar del sol 🙂
