Product Information

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.

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:Brand Reliability: When it comes to portable power banks, it's essential to choose a trustworthy brand. Brands like Anker have a solid reputation for producing safe and high-quality products, ensuring your devices are charged efficiently and without any risks. We put all these solar panels through side-by-side testing to ensure consistent conditions for every panel in every test. 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?

The sun won't always be out when you're on a camping trip, out at base camp, or just looking for a charge from the sun. An equally important metric is how well a solar panel works when the sun isn't directly out. We tested the panels in full shade and partially shaded conditions and saw how much each panel put out.The autofocus works a treat, as does the auto keystone feature. I've never had to manually adjust it myself so far. Charge it Fully: Plug in your power bank and let it charge fully before using it. This ensures that it's ready to provide a reliable power source when you need it. 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.
