Gadling Gear Review: Solar Chargers For Travel

Keeping all of our electronic gadgets charged while traveling can be a real challenge, particularly if you're visiting a remote part of the world where electricity is at a premium. But just as the gizmos we carry with us have gotten more sophisticated so have the options for keeping them powered. One of those options is taking a solar charger with us when we hit the road. A solar cell provides clean, efficient and, in theory, limitless power for our tech toys.Here are two distinctly different solar chargers aimed at very different types of travelers. Both are excellent for what China Outdoor Offers do, and while they each use light from the sun to create electricity, their similarity pretty much ends there.
The Classic2 is Solio's second-generation, travel solar charger, replacing their older Classic model, which was one of the earliest compact chargers on the market. The Classic2 improves on its predecessor in some key areas making it a much more efficient option to have in your pack when you travel. Those improvements include doubling the battery capacity and adding a full-size USB port integrated into the device. The previous version came with a number of special adapters, which were incredibly inconvenient to carry along on a trip. Since most devices, including smartphones and cameras, now charge via USB, this was an evolutionary, but very welcome, change.
The Classic2 features three small China Solar chargers for Iphone Offers, each embedded in its own arm. When collapsed the device is small, lightweight and compact. It weighs just 10.1 ounces and easily slips into a backpack, carry-on bag or luggage. When ready to collect energy from the sun, it opens up like a flower, exposing all three cells for maximum efficiency. The energy is then stored in a 3200-mAh internal battery, which in turn is used to charge our devices via the built-in USB port.Solio says that it should take 8-10 hours to charge the Classic2's internal battery from the sun, but in my testing it was definitely closer to the high side of that estimate, if not longer. Cloudy days and the amount of exposure to direct sunlight can impact that charging time dramatically. Fortunately, the internal battery can also be topped off from a wall socket or from a USB port on a computer. In both cases, it takes roughly six hours to charge the battery.The built-in USB port on this charger provides up to 1 Amp of power, which puts it on par with a typical wall charger. That means it can charge a smartphone or MP3 player in fairly short order. Solio claims charging an iPhone takes about 90 minutes, although again I found it took a bit longer.
