    Customer Reviews

    I bought this for dry camping in my RV. I wanted an easy way to recharge my multiple Ipads, iPhones, and computers. I just returned from an 18-day trip, and the Jackery 500 with the 100-watt solar panel performed flawlessly. Recharging it was the easiest system I have ever worked with. In sunny AZ, the system went from 83% to 100% in 2 hours. If it was cloudy, I plugged into my 12-volt plug while driving and generally went from the low 80s to 100% within a 3-hour drive. I have not used the 120-volt charger yet as it was not needed. In total, I recharged 2 Ipads, 2 phones, 1 computer, and 1 jet pack overnight. The battery would be in the low 80% by morning, sometimes 75% by evening back to 100%. I highly recommend this system.

    Jackery 500 gave me a lot of power for 7 days of camping. It powered my Alpicool ref, USB lights, cell phone, etc. The lowest power I had overnight was 87% until I could charge my solar panel the next day. I highly recommend this. I will use my CPAP on my next trip and trust it will give me power all night. I used Goal Zero before. I was not impressed, and Jackery’s price is more reasonable. Buying expensive things like goal zero does not prove great performance but is overrated as a waste of money. Go for Jackery. It is also lightweight.Maria

    The best solar phone charger. our top 5 list

    The sun is an incredibly powerful source of energy that is readily available to us for free. On a clear and sunny day, the energy from the sun can generate up to 1000 watts of power per square meter. While modern photovoltaic panels are not 100% efficient, they can still produce around 200 watts of power per square meter. This means that even a small installation of solar panels can generate a significant amount of energy.

    To put this into perspective, a typical smartphone charger can output anywhere between 5 watts and 25 watts of power, with some of the more advanced super-fast chargers capable of pushing the limit up to 100 watts. With solar panels producing up to 200 watts per square meter, the potential for harnessing solar energy is enormous. Is this the case, though? Read on to find out!

    Can a solar charger charge my smartphone?

    If you’re someone who enjoys spending time outdoors, particularly in the mountains, getting a solar mobile charger is a practical option. But picking the best solar phone charger can be hard because there are so many brands and hidden factors.

    A general guideline to keep in mind is that you’ll need a minimum of around 7 watts of power to charge your phone using a solar phone charger, but the more power, the better. It’s also essential to check if the solar charger has a built-in battery, particularly if you’re using it overnight when there’s no sunlight available. Without a battery, the solar charger would be as useful as a piece of paper when your phone dies at night.

    Portability is also a crucial factor when selecting a solar phone charger since you’ll likely use it on the go, far from any wall sockets or other luxuries of modern society. For frequent travelers who don’t want to add any extra weight or bulk to the backpack, lightweight and foldable solar phone chargers are the best option. However, it’s worth noting that if you want more power, you’ll need a bigger solar panel to capture more light, which may mean a bulkier device.

    Without further delay, here’s a list of the top solar phone chargers that you can get in 2023. These chargers have been carefully selected for their power output, portability, durability, and overall value, and they will ensure that you can keep your phone charged even when you’re off the grid.
