Whether it’s a smartphone for navigation, a satellite messenger for safety, or even a Kindle or earbuds for entertainment, a good portable solar charger can be essential on a long remote adventure. One issue that came up a few times was its issue with some Apple products. We discovered, as some other reviewers have pointed out, that this portable solar charger does better connecting to Apple devices when it is equipped with Apple-compatible cables.

The amount of wattage depends on amps and also volts. Volts are the amount of force of electricity, and multiplying amps and volts will equal the wattage. A higher number means higher power output. Efficiency When you consider the larger picture – i.e. efficiency and performance, the slightly heavier weight hardly matters. It’s a trade-off we totally accept for this solar charger. With the high efficiency from sunpower solar modules you can still expect good decent output under overcast conditions, unlike the smaller 10w panels that struggles to achieve max charging current.

It has four panels, permanently linked, that each deliver seven watts for a combined total of 28 watts. It only has USB-A outputs, so the voltage output isn't as high as some USB-C or DC output models, but that doesn't seem to make a difference because this panel charged our devices the fastest again and again.

For those who enjoy their camping to be a little more stationary, such as car camping or RV camping, a reliable solar charger is still a great investment. Save your car battery from charging your cell phone and speakers and use solar charging instead. Accidentally draining your car battery on a family camping trip can put you in a dangerous situation. In addition, there’s a short circuit, overcurrent, and fail-safe protection. Your gadgets are totally safe using this charger. In addition to that, the safe charging features prevent any overloading and keep your gadgets safe.Having said that, the high-quality of the inductors and the efficient voltage regulators mean it delivers optimum performance. This solar charger is best used if you’re a solo traveler. It only has one USB port, two solar panels, and doesn’t have that much power output for charging devices. The charging speed of the BigBlue solar charger is excellent under the full sun but when it gets cloudy, the charging speed does drop a tad. In fact, with the combination of its quality construction and the very fair price, we feel it’s one of the best solar chargers out there. This solar power tech isn’t yet perfect as heavy shade can disrupt the charging and it won’t readjust when it clears, but keeping an eye on your cell phone or device may quell that issue. We found this to be frustrating when we tested outdoors on a partly cloudy day. On our sunny test day when the sun’s power was at its peak, it performed perfectly.

The BigBlue solar charger comes loaded with a range of advanced technical features. This enables it to deliver superior efficiency and fast charging speed.According to the product listing, the BigBlue Solar Charger is waterproof, however, no specific waterproof rating is given, which made testing this detail a little challenging. Determined to figure out just how far I could push it to the limits though, I started with small spritzes of water from a spray bottle and worked my way up to completely submerging the solar panel section into a bathtub full of water. On the Big Blue Solar panel. I wasn’t very satisfied with it. After sitting in the sun for Four hours,I made a small charge on my iPhone. The Mac book next to nothing. This particular solar panel was not so good either on doing multiple charges at once.I had a friend use it with a cheap flip phone in which had a better bit of charge. I phone, Mac books not so good. Before my experience to use I should have researched the product to what it really could do. All companies claim they have great products until the user sets out into a venture and we expect that company experience to be really accurate. Put it to the test yourself a bit Finally, the great price combined with all these features definitely gives it the edge over the competition… To top it off, it comes with a built-in ammeter which allows you to measure the current output at any moment.
