Jackery solar charger for iPhone, Samsung, etc., is specially designed to keep your devices safe while charging. Different sizes of solar panel chargers for cell phones are equipped with powerful batteries, protection systems, etc., making Jackery products the top choice of campers.

Battery Capacity Of iPhone, Samsung, And More

Solar chargers are built for outdoor usage, and they are powered with the help of sunlight. While choosing the best solar charger for your needs, analyzing the solar panel size, charging speed, battery size, and the number of ports is essential. Watt and watt-hour should be considered to narrow your research and purchase the best solar panels.

What Are Watt And Watt Hours?

A watt is a power unit that measures the energy transfer rate. In electrical terms, the watt is the rate of electrical work done by a device during appliance powering.

The simple formula of watt is equivalent to volt-ampere. Here is how to calculate it:

Watt = Volt * Ampere

Power is the energy rate at which energy is consumed or generated; hence, it is measured in watts. Meanwhile, watt-hour is the rate at which one-watt power is consumed in one hour. Here is the formula to calculate the watt-hours of any device.

Watt-Hours = Total Number Of Watts * Total Number Of Hours

Battery Capacity of Phones

Generally, a solar phone charger that can supply 10 watts is sufficient to charge a smartphone for one day. Many solar power panels have robust battery protection systems, so you can power all your devices safely.

For instance, if you know the battery capacity (mAh) and volt (V), you can easily calculate the watt-hour.

Formula is (mAh) * (V) /1000 = Wh.

Suppose the battery capacity of the solar power charger is 300 mAh, and the volt is 5V. Here is how to measure watt-hours.

Watt-hour = 300 mAh * 5V / 1000 = 1.5 Wh.

Here is the breakdown of the estimated solar power needed daily to charge different types of smartphones.

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. Addendum photos first photo 11:48 am, 2nd 12:42 pm, 3rd 1:48 pm, 4th 3:02 pm, 5th 3:55 precharge in Tucson, AZ. May 23, 2021 Went from 100% to 81% after charging 2 Iphones, 2 Ipads, and 1 jetpack. 1 Ipad in use for a couple of hours while being charged. --Susan"

"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"

Even if the portable power station is out of capacity, you don't have to worry about charging your appliances. The pass-through charging capability lets you recharge the device and solar generator at the same time. In addition, the input and output ports on the portable solar generator protect your device from overcharging.

What Size Solar Charger For a Phone Do I Need?

Solar cell phone chargers come in different sizes, shapes, and types. The simple rule to purchasing a solar panel is understanding its compatibility with your device.

Calculate the size of the solar charger for a phone with this formula:

Working time = Watt-hour of the solar power station * 0.85 / operating wattage of your device.

For instance, if we assume that the cell phone consumes 10 watts and the watt-hour of the solar power station is 167Wh, the working time will be 167 Wh * 0.85 / 10 = 14.2 hours.

Purchasing a solar power station with a 167 Wh battery capacity can charge a phone at 13 Wh capacity 11 times. You can calculate the number of charges a solar panel supports with a simple formula:

The number of charges supported = 0.85 * Power station capacity/phone capacity.

Depending on the requirements and phone capacity, you can determine the size of solar panels you'll need.
