Generally speaking, more solar cells mean more watt output. Watt output is much like solar panel size, as you can see. General Wattage Guidelines Notes: Brightness (light output) will vary depending on usage conditions. Light output is measured in accordance with ANSI IT7.228-1997. The nominal value represents the average value of mass production and is tested under ideal laboratory conditions. The size of your power bank depends on your specific charging needs. For everyday electronics like smartphones, earbuds, or similar devices, a power bank with a capacity of around 10,000mAh might be perfect. However, if you plan to charge larger devices such as laptops or tablets, it's best to go for a power bank with a capacity of 20,000mAh or higher. Read the Instructions: Take a few minutes to read the user manual that comes with your power bank. Familiarize yourself with its features, usage instructions, and safety precautions. This will help you make the most of your new gadget while keeping yourself and your devices safe.

What Other Solar Chargers Should You Consider?
This portable projector comes with a 65watt usb c pd charger that can be used to power other devices that support usb c charging The capacity to charge multiple devices at a time is a necessity for solar panels as often when one device loses charge, chances are that the other ones will as well. The 21W from Anker did an okay job at charging multiple devices. The battery charged the first port at 809 mAh and the second at 635 mAh, which was a bit below the rest of the devices. Portability You don't always have ideal blue skies and sunny days when using a solar panel, so we also tested how well a solar panel performs in cloudy conditions. Most solar panels don't work as well in partial or indirect sun, but they still generate some power. Some panels are more efficient than others in indirect sun, so this is also worth considering when looking at solar chargers.
The only thing worthy of mention as a very slight negative is the noise from the fan. It isn't silent, but then again, it isn't ridiculously loud either, though I can imagine some may find it a distraction if you're expecting complete silence, like from a telly! Folded, the panel breaks down to 11.13" x 6.13" x 1.13" while unfolded it is 26.25" x 11.13". For being a tri-fold panel with a large surface area of cells, the 21W is small and sleek. When folded, the width is about the size of a thin book or a magazine. Should You Buy The Anker 21? Once you've figured out the type of solar panel that will fit your needs, looking at specific features of different individual models will help you narrow down the field. Solar Panel Size None of the solar panels we tested here are designed to be permanently mounted to a roof, so they're all at least somewhat portable. But some chargers are certainly lighter and smaller than others. Small and light solar panels are more portable than big panels, but those bigger panels will generate more power than something more portable.
The verdict: Solar chargers
Functionality measures how easy it is to use the charger. When testing functionality, we asked ourselves, "How user-friendly is this panel?" In thirty minutes, the 21W from Anker charged a Pixel 3 from about 30%. This is impressive and on par with some of the larger capacity panels in this review. The SolarPowa 28 isn't the absolute fasting charging portable panel, but it still charges fast enough. And if you need an ultralight solar option, this panel also might not be the best choice. At 21.8 ounces, there are certainly lighter models out there to consider. But if you need a lot of consistent power in a relatively portable size, the BigBlue is a great option we highly recommend. And it's pretty affordable to boot. Congratulations on your new power bank! To ensure you get the most out of it, here's what you should do when you first buy one: Entertainment Tailored to You: Choose from more than 5,000 apps with Android TV 9, including favorites like YouTube, Hulu, and more. You can even mirror content from your smartphone or other devices to Solar Portable 1080p projector. Note: For peak performance, please update to the latest firmware.
Ports: Different devices have different charging ports, and your power bank should be compatible with them. Look for power banks with the right ports, such as Lightning or USB-C, to ensure seamless charging for all your devices. Having multiple ports is a bonus, allowing you to charge multiple gadgets simultaneously. The Renogy 100W Foldable is an impressively sturdy panel with a beefy aluminum frame and legs. It's just as rigid and sturdy as a panel you'd install on your house — but has a single hinge for transport. Compared to the many thin, slightly bendable solar chargers we've tested, this one feels just about bombproof. Though it's tempting to mount this waterproof beast to the roof of our van, it also has seriously sturdy, fully adjustable angling legs that help it angle precisely into the sun no matter where it is in the sky (or behind the clouds). If that's not enough, this panel put up some of the best energy efficiency results across all the models we tested, rain or shine. The Anker 21 is well made, light, and compact. It can also carry its weight as a charging powerhouse. It's okay when charging one or more devices, and can recover its charge even after being shaded for a few minutes. The panel also works decently well on overcast days, whereas some of the lower wattage panels could not keep a charge going when clouds were overhead. We are big fans of this long-time favorite, but the Anker 21 has finally come up against some fierce competition in recent years. Auto focus works great everytime and hardly needs to be messed around with as well as the auto keystone correction We put all these solar panels through side-by-side testing to ensure consistent conditions for every panel in every test.Battery lasts 3.5 hours on battery saver mode or 2 hours on standard mode broghtness does drop slightly when in battery saver mode but not by much watts to 30 watts: Many of the portable solar chargers we tested here fall into this wattage range. 20 to 30-watt chargers are great for faster charger speeds while still being relatively portable.
