How much time does it take to charge a solar phone charger?

1. Why solar phone chargers?

With the rapid development of the solar PV technology, the benefits of the technology continue to increase since now we can use solar energy to directly power your cellphone and other gadgets in your household using, for instance, a portable solar generator or a stationary solar generator depending on your intended use of solar energy.


A solar phone charger comes in handy for people that do a lot of outdoor recreational activities such as hiking, camping, mountaineering, cycling, canoeing, caving, kayaking, rafting, rock climbing, running, sailing, skiing, skydiving, and surfing. Since most of these outdoor recreational activities involve traveling to remote places away from the grid, having a portable energy source would help to solve the problem, especially if you need to charge the battery of your cellphone when far away from the power grid.

In most cases, when people travel and need to charge the battery of their cellphones, they use their car chargers by plugging them in their car charging port to keep using their mobile phones. However, in some cases depending on the activity of the day, you will need to solve the problem with a solar-powered phone charger, especially when your recreational activity involves hiking, mountaineering, kayaking, etc.

One way to solve this problem is using a solar cellphone charger that incorporates an external battery pack attached to a series of solar panels that can be connected to the general electric supply or to the connector of an automobile vehicle lighter for charging the battery in the absence of solar light. Although it is a good thing to have a solar charger that can recharge all of your battery-powered electronic equipment such as your GPS, smartphone, camera, or flashlight and that can be recharged easily as well using solar panels.

2. So, how long does it takes to charge your solar phone charger?

Basically, a solar phone charger uses solar panels to charge a rechargeable external battery pack which in turn charges your cellphone. By knowing that solar panels would produce electricity even on cloudy days, your solar phone charger can charge the battery of your phone if there is some sunlight to trigger the electrons on your solar panels creating electricity (movement of electrons).


How long your solar phone charger takes to charge the battery of your cellphone depends on the wattage of your solar panel. High wattage means more solar power is harvested by your solar panel per unit time and depending on your external battery pack size, it is a matter of time depending on the types of solar batteries being charged.

3. Charging a solar phone charger.

Before we answer this question, let us understand the external battery pack that is being charged through the solar panels in your solar-powered phone charger. Solar batteries vary in several parameters, including capacity, output, size and weight and there are three types of solar battery banks:

• NiMH (Nickel Metal Hydride) batteries, usually the rechargeable AA or AAA batteries which are sold in packs.

• Lithium-ion batteries are the most common for portable battery backs.

• Lead-acid batteries not great for portability, because they are heavy and bulky, but very reliable when it comes to power output and capacity.

So, how long it takes to charge your solar-powered phone charger is a little complex and it is advisable to understand some electrical terminologies to understand the concept of charging your solar batteries:

• V — Voltage (electrical potential in the system, measured in volts). The higher the voltage, the more power you get out of a battery. A car battery has 12V and a USB port is usually fixed at 5V.

• Amps (A) – Current – the amount of electricity. General plugs are rated at 9A while big power devices like air conditioning (AC) systems are rated at 15A while smartphones draw current at 1A.

• Watts – Wattage (power measured in W) which is voltage (V) multiplied by Current (Amps)

Hence, if you have any of the above two numbers you can figure out any of the numbers. Batteries and gadgets like your smartphone are considered as small power and are measured in Amp-hours (Ah) or milliamp-hours (mAh) since 1Ah = 1,000 mAh which includes the rate of charging your solar battery bank.

Since most gadgets, including cellphones today, charge off USB (fixed at 5 V) we can calculate the time taken to charge your solar-powered phone chargers as (power bank capacity) divided by (power generated by the panel) using the parameters provided by the manufacturer. For instance, the manufacturer has set a certain number of amps needed to get a healthy charge in a reasonable amount of time.



So, if your cellphone is drawing a current of 1A we know that phones charge off USB at a voltage of 5 Volts, then such a cellphone draws 5V x 1A = 5W and considering for instance how long it takes to charge the following solar phone charger using solar? i.e. the Amazon, Solar Charger Power Bank 25000mAh Portable Charger Battery Pack with Three Outputs & Dual Inputs Huge Capacity Backup Battery Compatible Smartphone, Tablet, and More.

As we have noted above, this type of solar charger will depend on several factors. First, what is the current output of the solar panel? If the solar cellphone charger claims a 2W panel, it will produce electricity of 400 mAh at 5V (assuming there are no losses). That’s 400mA per hour, then if the capacity of this solar power battery is 25000mAh as rated, then 25000 mAh divided by 400mA is approximately 62.5 hours to fully charge your solar battery pack in the sun. Therefore, you probably need to buy a few pairs if you plan to stay outdoors for a long period while also plan to keep these solar battery packs topped off.

Powering your mobile-phone using a solar phone charger.

As the solar photovoltaics (PV) technology continues to advance we are seeing a lot of technological breakthroughs that use photovoltaics to help power homes, gadgets as well as businesses. These technological breakthroughs range from solar generators for homes, solar chargers, solar panels for RVs, and many other solar PV gadgets.


When it comes to solar phone chargers, they can be used to charge your phone by the use of solar panels and they are useful in remote areas not connected to the grid. A solar phone charger is a portable device or gadget that is solar powered or uses solar panels to supply electricity to electronics. An extended-life battery pack is usually included in a solar phone charger to store electricity for later use.


Although you can still own a solar phone charger if you enjoy outdoor activities like hiking camping etc to use it to recharge your phone or your camera. Just like there are so many brands of solar phone chargers today, there are also many types of the same and most of which can be purchased on Amazon.com.
