Nekteck 28W Foldable Portable Solar Charger with 2 USB Ports - IPX4 Waterproof Hiking Camping Gear Sunpowered Charger for iPhone 12/11/11pro/Xs, iPad, MacBook, Samsung Galaxy, Camera and more. Review

I first tested this product for about two weeks. I charged a power bank during the day and used the power bank with the wireless charger at night. Each USB can put out around 7 watts during the daytime peak. Using only one USB will not speed up charging. I had trouble charging on cloudy days. I was doing it just for fun until a derecho came to my town. 97.5% of my county had no electricity. There is currently no electricity in my house. I no longer use wireless tablets because I need maximum…

I ordered this solar panel for a week long trip. I have an external battery but it's only enough to charge my phone for about 3 nights. While not as fast as a traditional charger, I was able to use my phone as a camera for the duration of the trip. Even on an overcast day, I was able to charge my phone before reaching camp that evening by attaching solar panels to my backpack during the day's hike. It's slightly larger than my battery but weighs about the same and is flexible. Attached to the…

We have been using this panel for a few months now and are very satisfied. I typically use lots of batteries to charge various items including phones, tablets and other random items around the house. So I use this to charge most of them during the day. I live in upstate New York and wouldn't say we have the most solar power, but I can typically fully charge two 6-10,000mAh batteries in a day or so while sitting on my car's dash while parked. a lot during work. So far it has been very durable…

Bought a few weeks ago and tested with different items. I mainly use it for charging AC adapters/battery not for what I will be using. I find it safer to charge a standalone battery than a $1200 phone. So far the biggest charger I've used it on was 10,000mAh which also had a built in solar panel (HyperGear). It charged from empty to full in 2 days on my balcony where it was exposed to direct sunlight for about 7 hours. It may have charged it in less time since I didn't check it very often…

to its weight and maximizes the output of solar energy per unit weight. While there are quite a number of lightweight offerings to choose from, many of them have inaccurate weight misinformation. For example, the 30W foldable solar charger advertises a net weight without accessories of 540g (19.2oz), but the measured weight after purchase was almost 700g. Another 28w version advertises 21oz but was measured by OutdoorGearlab at 23.5oz. The measured weight of this 4-panel solar charger…

I bought this solar charger out of curiosity - do a few small solar panels really produce enough electricity to charge a cell phone? After purchasing and trying this item, I can say with confidence that they work! The solar charger is well made and gives a pleasant feeling of solidity and rigidity. It folds easily to fit in a bag or car, and without lots of cables in the case, it's surprisingly thin. Keep in mind that putting a bunch of cables in your pocket will add thickness, but still not…
