    After a few years

    Initially I loved it. But it’s one of those things keep for emergencies or in a camping situation. After about the 10th or 12th time using it I noticed a decrease in efficiency in energy stored. If you are hoping to have it fully charged using solar power you were looking at a full month if not longer to get it from charge just by solar power alone. The most ideal way to use it is when you’re charging the phone or whatever electrical device you’re using be sure it’s being exposed to solar power if you’re in that situation where you have no way to plug it in.

    Looks like a quality built item

    Have only charged the phone once so far. It is a solid, quality built item. Have not had the opportunity to charge using the solar panels yet.

    Do all four panels have to get sun for one USB port to charge?

    All the solar panels need to be exposed under direct sunlight, otherwise, the solar panels that are not exposed to the sun will become resistors, making it impossible to charge.

    Do the panels have auto-restart while in the sun?

    Of course. It starts charging again the moment it produces enough output for the attached device to charge.

    What features to look for in a solar phone charger

    When you’re shopping for a solar phone charger, there are a few things to keep in mind to make sure you get the right one for your needs, including:

    The Best Solar Phone Charger For Smartphones Tablets?

    After the incredible success of the Voltaic Fuse 4 Watt solar charger on my previous 14-month-long bicycle tour in Europe and Africa, I decided to upgrade to the larger and more powerful 6 Watt solar charger on my travels this year. While the two products are similar in size, the new Voltaic Fuse 6 Watt solar panel produces 50% more electricity by way of its larger surface area and is the perfect size for charging smartphones, GoPro video cameras, tablet computers and other small USB-powered devices.

    With the universal attachment system that comes standard on all of the Voltaic Fuse products, the Voltaic Fuse 6 Watt solar charger connects in seconds to backpacks, bicycles or wherever solar power is needed. Available in three different colors and priced at only 129 USD, the Voltaic Fuse 6 Watt is the perfect device for charging any USB device – including all Apple, Android and Blackberry smartphones.

    You can see my 6 Watt charger in use in the image above (it’s resting on top of my bicycle’s saddle) and in the various photos throughout this review.

    How Does It Work?

    The Voltaic Fuse 6 Watt solar charger works in two distinct ways:

    The first and easiest way to use the product is by connecting the small battery that comes with the Fuse to any standard power outlet. Once the battery is fully charged, simply connect the included battery to any USB-powered device that you wish to recharge.

    The other (and more obvious) way to use the Voltaic Fuse 6 Watt charger is to leave the product out in the sun for several hours. The more sunlight that hits the panel, the faster the internal battery will charge. Once the battery has generated a charge, simply attach your smartphone, video camera, or any other USB-powered device. It’s simply that easy!

    The company that produces the Fuse 6 Watt panel (Voltaic Systems) says that 3 hours of direct sunlight will charge a smartphone, 6 hours in the sun will charge a small tablet, and 11 hours of sunlight will fully charge a larger tablet computer.

    My experience with the product tells me that these estimates are pretty darn accurate, but it should be noted that “direct sunlight” is necessary for this type of optimal charge. Cloud-cover of any kind, or placing the solar panel at an improper angle, will increase the amount of time needed for the included internal battery to fully recharge.

    On a personal note, I’m able to charge my Samsung Galaxy S4 Mini smartphone approximately 2.5 times from the fully-charged Voltaic V39 battery. However, the size of your smartphone battery and/or other electronic device will determine how many charges you can generate from the included battery.

    To learn more about how the Voltaic Fuse 6 Watt functions, please see my previous review on the smaller Voltaic Fuse 4 Watt or my video review of the larger Voltaic Fuse 10 Watt (both of which operate in exactly the same way). The only real difference between these three products is the size of the panel(s) on the front of each charger and the type of battery included with each device.

    My Experience With The Voltaic Fuse 6 Watt Solar Charger

    I’ve been using the Voltaic Fuse 6 Watt Solar Charger on a daily basis for the last 6 months. I’ve been bicycle touring across more than a dozen different countries in Europe and Asia over this time period and the 6 Watt Fuse has been responsible for keeping my smartphone charged for much of this time.

    There is, however, a major difference between my bicycle tour this year and the one I conducted in 2012/21013 with the smaller 4 Watt charger. This year (2014) I upgraded from a small iPod Touch to a much larger Samsung Galaxy S4 Mini smartphone. As a result of this upgrade, the amount of power needed to keep my smartphone charged (which I use for work, entertainment and navigation while I’m traveling) has increased significantly. My new smartphone has a much bigger battery than my old iPod Touch and I’m using the device more often as well (while at the same time demanding that it perform more complicated tasks). This has resulted in me draining my smartphone’s battery at an unprecedented pace.

    It didn’t take me long to discovered that even my larger 6 watt solar panel wasn’t going to be enough to keep my smartphone charged for weeks at a time. If I wanted to keep my smartphone charged for long durations, I was either going to need to drastically reduce the amount of time I spent on my smartphone each day (thereby saving the phone’s battery), or I was going to have to figure out a way to charge my batteries at a more Rapid pace.

    What I ended up doing was upgrading to the larger V39 battery (which is an optional upgrade with the Voltaic Fuse 6 Watt charger) and ordered a second V39 as a backup as well. With these two large batteries in my possession, I constantly had one of the batteries charging on the solar panel, while the other battery was working to charge my phone. When the battery running my phone ran out of juice, I’d simply switch the batteries with one another, replacing the battery in the solar panel with the one that was now drained. Because the battery coming from the solar panel had been charging for a day or more at this point, it was usually near full and ready to expel its built-up electricity into my waiting smartphone. This process of swapping the batteries back and forth allowed me to keep my smartphone powered for a week or more (even with moderate daily use).

    bigblue, solarpowa, sunpower, solar

    It should be noted, however, that even with two batteries, I’m a pretty heavy smartphone user… and if you’re anything like me, you should know that using a solar charger like the Voltaic Fuse 6 Watt is not the same as having your smartphone constantly plugged into a power outlet. If you want to go for long periods of time using the solar charger as your only electricity-generating device, then you need to be conservative with your electronic use. Even with two of the larger V39 batteries in my possession, I’d eventually run out of electricity and need to find a power outlet in which to charge my various electronics.

    Would I Recommend The Voltaic Fuse 6 Watt?

    Solar power is pretty darn incredible… and small solar chargers like the Voltaic Fuse 6 Watt are quickly becoming standard pieces of equipment for hikers, bikers, and modern travelers of various kinds.

    If you have a smartphone, GoPro video camera, tablet computer or other small electronic device you want to keep powered either at home or out on the road, there are few products out there that could serve you better than the Voltaic Fuse 6 Watt.

    Currently priced at only 129 USD, the 6 Watt Fuse is the perfect size for hiking and/or cycling. The charger fits perfectly onto the back of a backpack or on the front or rear rack of any type of bike. The 6 watt panel is large enough to produce a significant amount of electricity, but small enough that it doesn’t weigh you down or take up a lot of room. Plus, you can use the included USB battery to keep your electronics charged at all times – whether you’re traveling close to home or on the other side of the planet. The battery alone is worth the price of purchase in my opinion!

    While the Voltaic Fuse 6 Watt solar charger isn’t large enough to power DSLR camera batteries or laptop computers, it is the perfect device for charging smartphones, tablets and other small USB-powered electronics.

    I imagine I’ll be using the Voltaic Fuse 6 Watt solar charger on my bicycle tours for the next several years… and I recommend you look into using one for your travels as well.
