The most effective photo voltaic chargers on your telephone or pill


Let’s face it, our phones are often about to shut down, usually due to a dead battery. This is especially frustrating on a hike, camping trip, or other outing where you might rely on your phone for GPS coordinates.

Fortunately, the sun is always on – at least during the day – so why not use the energy of the sun and keep your devices running even when you are hiking in the middle of nowhere? After months of testing, we decided on that BigBlue 28W The best solar charger for backcountry power thanks to its affordable price and efficiency. However, if BigBlue’s range is too big for your needs, we have some alternatives.

BigBlue 28W solar charger

  • Capacity – None (panel only)
  • Outputs – 2 USB (2.4A)
  • Weight – 22 ounces
  • Solar panel – 28 watts

Many solar chargers are marketed as portable solar options, but few match the BigBlue 28W solar charger. The device is not the smallest panel on the market, but it offers considerable performance. The solar panel charges quickly and reliably even under adverse conditions and then charges several devices quickly. With a manufacturer’s recommended price of $ 60, the Big Blue is also easy on the wallet. The only catch is that BigBlue doesn’t contain a battery. You will either need to charge your electronic devices directly or provide your own portable battery.

Renogy E.FLEX 10W

  • Capacity – None (panel only)
  • Outputs – 1 USB port (1.92 A)
  • Weight – 13 ounces
  • Solar panel – 10W

While the Renogy E.Flex doesn’t have battery support (meaning it’s only useful in sunshine), it’s one of the cheapest panel-only options that gets high marks for both durability and chargeability. A 1.92A USB port should provide enough power to charge your phone at about the same time as traditional power and even power your phone without draining the battery in full sunlight. These are many other panel-only options, most of which are more expensive – can’t. There’s a 5-watt model on Amazon for just $ 24, but it produces less than an amp of current on the USB ports, making it inadequate for many uses.

NekTeck 21W solar charger

  • Capacity – None (panel only)
  • Outputs – 2 USB ports (total up to 3A)
  • Weight – 1.3 lbs.
  • Solar panel – 21W

Although Nekteck has no battery storage capacity, we love solar charging with up to 21 watts of power generation, which is more than enough to quickly charge any portable device. In contrast to most pure solar chargers (those without a battery), the Nekteck model can charge up to two devices at the same time. Keep in mind that you are limited to 3 amps total so it will take much longer to charge two devices. Another nice feature is SmartIC, which intelligently detects the device type and delivers just the right amount of power to charge your phone, tablet or GPS as quickly as possible.

Unlike some of the chunkier hard shell structures on the market, the Arc 20 Watt Solar Charger easily attaches to a wide variety of awnings, backpacks, and tents so you can charge evenly throughout your adventure. This 20W kit also includes the Voltaic V88 Universal Laptop Battery, which has a DC output so you can charge most laptops at least once. The external battery also provides protection against short circuits and overcharging so you don’t have to worry about frying your appliances.

Nature lovers will be delighted because this superior transportable power stone is for you. The Panergy solar charger offers 18 watts of power and a sturdy armored case that will hold up well under most conditions that nature throws at you during a hike or a camping trip. Additionally, the IPX1 weather protection can withstand most types of rainfall, and the durable ABS material keeps the pack free of unwanted dust and debris. Juicing an empty battery takes approximately eight hours. Once the battery is fully charged, it can charge both a Galaxy S10 and an iPhone 11 at least six times. Panergy’s charger is built with safety in mind and has a powerful LED that allows you to flash a distress signal from over 300 feet away. The charger is intentionally orange in color to repel insects.

Dizual 5,000 mAh portable solar charger

  • Capacity – 5,000 mAh
  • Outputs – Dual USB output (up to 1A)
  • Weight – 0.5 pounds
  • Solar panel – 1.2 watts

At a surprisingly low cost of $ 15, you get way more than what you paid for with the Dizual charger. This charger is packed with useful features, a backpack-ready design and a lanyard that you can use to attach it to the back of your bag. We wholeheartedly recommend this charger.

The eco-friendly design of the pack is also made of tough ABS materials, so you don’t have to worry if it falls or rains lightly (but don’t dive into ponds). The two USB outlets have rubber caps for protection to keep dirt and debris from clogging your ports. The built-in row of LEDs shows how much power is left in the pack.
