Still curious about the "BigBlue 28W Solar Panels Charger"? Here are some answers you might find interesting:

☀️

How much power does the BigBlue 28W Solar Panel Charger output in full sun?

The BigBlue 28W Solar Panel Charger is pretty useful, especially when you're outside and need to keep your devices powered. To get the most juice from it, you'll want to have it in full, unobstructed sunlight. According to the manufacturer, under ideal conditions, it can achieve a solar conversion efficiency of up to 24% with its SunPower solar panels. So, on bright, sunny days, you can expect it to work at its peak. But keep in mind, if any part of the panel is in the shade or if it gets cloudy, that efficiency can drop—sometimes quite a bit. Our research shows that even a little shade or cloud cover can slow down the charging or even stop it altogether. So, it's a good idea to keep the panels as exposed to direct sunlight as possible. The power output also depends on what device you're charging. For example, if you're charging something like an [iPhone](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DiPhone%26tag%3Dssw.ans.tx-1-20), you might see outputs between 0.8A and 1A depending on the sunlight and how much your device can handle. We've found that the charging speed can fluctuate, especially if the sunlight isn't consistently strong. Some folks have reported getting around 1.8A in direct sunlight, but noticed slower rates if it's not completely sunny. To make the most of your solar charger, there are a couple of things you can try. Keep your devices shaded or in insulated spots while charging to avoid overheating, which can be a problem according to some users. You might also want to pair the solar panel with a [power bank](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dpower%2Bbank%26tag%3Dssw.ans.tx-1-20). This way, you can collect and store power during the day and use it later, which means you won't need constant sunlight to charge your devices on the spot. So, while the BigBlue 28W Solar Panel Charger does best with full sun, its performance can vary based on several factors. Placing it carefully and using additional tools like a power bank can really help you stay powered up when you need it.

How long does it take to charge devices with the BigBlue 28W Solar Panel Charger?

Hey there! So, when it comes to the BigBlue 28W Solar Panel Charger, charging speed can really depend on a few things like how sunny it is and what kind of device you're charging. From what we’ve found, on a nice sunny day, this charger can fully power up a smartphone in about 2 to 3 hours. For bigger gadgets, like tablets, you might be looking at around 4 to 5 hours. Of course, these times can change based on your device's battery size. One thing to remember is that this solar charger works best in direct sunlight. If it’s cloudy or you’re in a shady spot, charging might slow down a bit. But all in all, it's a pretty good option if you need to keep your devices juiced up while you're out and about. There's also some handy tech built-in, like Smart IC technology, which figures out the best charging speed for your device and helps keep things efficient. It’s great because it adjusts even when the weather's playing up. According to our research, many found it useful for charging more than one device at a time, thanks to the three USB ports. Just a heads-up, though: sharing power between multiple devices might mean a bit of a wait. To get the best results, make sure you use it when it's super sunny and keep an eye on its angle for maximum juice. And maybe keep the USB ports dry so everything stays safe and lasts longer. Overall, while charging times can vary, the BigBlue 28W Solar Panel Charger does a solid job at keeping your gear charged when you're on the move.

💧

Is the BigBlue 28W Solar Panel Charger waterproof?

The BigBlue 28W Solar Panel Charger does have some water resistance, but it's important to know the details. The manufacturer gives it an IPX4 rating, which means it can handle splashes from water, like light rain or mist, but it's not fully waterproof. So, it's built to withstand a bit of moisture, but you can't dunk it in water. The solar panels are wrapped in a PET polymer fabric, offering a bit of protection against splashes. However, the USB ports and the ammeter are not water-resistant at all. Our research shows that it's best to keep these parts dry to avoid any potential water damage. Many who have used it suggest taking care to protect these components, especially in wet weather. One person mentioned that they used it in light rain without issues, but stressed keeping connected devices dry. If you're planning to use this solar panel somewhere damp, you'll want to be extra cautious with the more delicate parts. It’s like taking your phone out in the rain—keep it safe in a waterproof case or pouch. In short, while the BigBlue 28W Solar Panel is a great tool for different weather conditions, just be mindful of its limits around water. With a bit of care, you can keep charging away without worry.
