Whether that is on a camping trip, hiking or cycling, using the sun's energy is an environmentally friendly way to charge your electronic devices. But how long do solar power banks actually take to charge? Typically in direct, unobstructed sunlight, you should allow up to 50 hours to charge the battery on a standard (25,000mAh) power bank fully.
Small Capacity (2,000mAh – 5,000mAh): Power banks with small capacities typically take around 2-3 hours to fully charge. These power banks are perfect for emergency use and can provide a single charge for most smartphones. Medium Capacity (5,000mAh – 10,000mAh): Power banks with medium capacities usually take around 3-5 hours to fully charge.
So charging them completely takes a significant amount of power. As an estimate, a fully charged portable solar panel will recharge a phone with 5% battery life to full battery life in about two to three hours. It's nearly impossible to calculate exactly how long it will take for a solar-powered device to charge a phone.
Solar energy is one of the most sustainable and environmentally friendly ways to generate electricity. A solar power bank uses a small built-in solar panel to charge a rechargeable battery (usually a lithium-ion battery). The panel is a photovoltaic cell which is sandwiched between a semi-conductive material (usually silicon).
A smartphone uses 2 to 3 watts from its battery when in use. The battery holds a charge of 1,440 mAh, or about 5.45 watt hours. A solar panel will need to provide a minimum of 5 watts when charging. Ideally 10 to 15 watts of charging power is recommended. A lower wattage means that you will need more time to charge your phone.
There is no battery included in the unit but with USB outputs this will allow you to recharge your solar power bank more rapidly. And because it has 2 USB charging points you can be recharging your device and recharging the power bank at the same time, making the best use of any available sunlight!
