The best solar chargers for your smartphone or tablet

It always happens – when you need your phones or tablet the most, it wavers at the edge of the shutdown because you've drained the battery. It is even worse if you do not have immediate access to a power outlet. Fortunately, the sun is always on (at least during the day). So why not use the power of solar energy to keep your devices running, even if you're in the middle of nowhere? Below we have summarized some of the best available solar chargers, especially in terms of power and value. Most of them can replenish several of your devices with a single charge – as long as the sky is clear.

  Fuse 6W Solar Charger

  • Capacity – 4,000mAh
  • Outputs – 1 USB (1A)
  • Weight -1.3 pounds
  • Solar Panel -6.15 Watt [19659008] Many solar chargers are marketed as ultraportable solar options, but only a few up to the Fuse 6W solar charger. The device has a universal mounting system with a set of locking clips. This will allow you to attach the charger to the back of your current backpack and adjust the straps for a tighter fit. The fuse 6W charges an external battery. However, you can also charge the latter component through a standard power outlet or USB. In any case, after charging, the device should contain enough juice to fully charge the smartphone at least once. We tested the Voltaic backpack with a panel earlier this year. So if you have a special solar pack on the market, we recommend that you present our test report for the Voltaic OffGrid Solar Backpack.

      Best Solar Chargers
    • Capacity – 25,000 mAh
    • Outputs – 3
    • Weight – 19.4 ounces

    With a capacity of 25,000 mAh has RAVPowers outdoor charger about the largest capacity of any of our solar chargers list. Most outputs allow you to charge up to three devices simultaneously with the QuickCharge, USB-C, and iSmart charging ports. It even includes an LED emergency light with three lighting modes: Strong, Probe and SOS. If you are in a hurry, RAVPower gives you the opportunity to charge the power adapter via USB. This is probably a smart idea: RAVPower says it would take more than 80 hours to recharge your portable battery with sunlight alone!

    • Capacity: -19,800 mAh [19659005] Outputs – DC Output, USB Output (1A)
    • Weight – 3.25 lbs
    • Solar Panel – 19.8 Watts

    Unlike some of the harder hardshells, the Arc 20 Watt Solar Charger easily builds on the market, attaches to a variety of awnings, backpacks and tents for constant charging during your ride adventure. This kit also includes the Voltaic V72 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 do not have to worry about frying your appliances.

    Renogy E.Flex 10W ($ 60 MSRP)

    • Capacity – None (panel only)
    • Outputs – 1 USB port (1.92A)
    • Weight – 11.2 ounces
    • Solar Panel – 10 W

    The Renogy E.Flex does not have a battery backup (ie it's only useful.) When the sun is out there), this is one of the cheapest options available only for panel is suitable and offers top marks as well as durability and loading capacity. A 1.92A USB port should provide you with enough power to charge your phone in much the same way as you would with a traditional power supply, and even power the phone without the battery must be discharged in full sunlight. These are many other options that are only suitable for the panel – the most expensive ones – can not. At Amazon, there is a 5-watt model for only $ 24, but provides less than one ampere current for the USB ports, which is not sufficient for many applications.


      Yolk Solar Paper
    • Capacity – None
    • ] Outputs – 1 USB port (1A)
    • Weight – 4 ounces
    • Solar Panel – 5 W

    Solar Paper is that thinnest available solar charger. The device measures only 0.45 inches at the thickest point. Although it has no built-in battery, a display on the top of the device will tell you if the charger has enough power to charge your device. Theoretically, this solar charger could worry without a battery. There are several options available, from the simple 5W version ($ 148) to a 15W version ($ 348). Keep in mind that if you want to charge your phone, or if you want to charge tablets or multiple devices at the same time, you will need the 5 watt model when charging your phone or the 10 W power adapter.

      Best Solar Chargers 21w Charger
    • Capacity – None
    • Outputs – 2 USB Ports (up to a total of 3A)
    • Weight – 1.3 lbs
    • Solar Module – 21 W

    Despite the lack of battery storage capacity Necktek's solar charge impresses us with a power production of up to 21 watts, which is more than enough to charge any portable device quickly. In contrast to most solar chargers (chargers without battery), Necktek can charge up to two devices at the same time. Remember, however, that you are limited to a total of 3 amps. The loading of two devices can therefore take much longer. Another nice feature is SmartIC, which intelligently recognizes the device type and delivers just the right amount of power to charge the device as fast as possible.


      ECEEN 13W 2-Port
    • Capacity – not specified
    • Outputs – 2 USB ports
    • Weight – 9.3 ounces
    • Solar Panel – 13 W

    The ECEEN 13W 2 port is one of the best 13W chargers we've ever seen. The entire unit weighs only 9 ounces and measures an inch thick, making it exceptionally lightweight and compact. A handy pocket on the back of the charger lets you store your mobile phone, iPad mini and other mobile accessories while charging or on the go. A simple stand on the back of the unit adds even more functionality and gives you the ability to position the solar charger in direct sunlight. The ECEEN model is currently one of the most affordable solar chargers on the market, under $ 40.
