1. What's the real capacity of a 10000mAh power bank?
Our 10000mAh power bank has a nominal capacity of 10000mAh. However, due to voltage conversion (from 3.7V to 5V) and efficiency losses, the actual output capacity is approximately 6800mAh. This allows you to fully recharge a 2500mAh smartphone about 2.5 times, making sure you stay connected longer! 🔋 (Please read this article for more information)

2. Could it damage my phone?
Absolutely not! Our power banks are built with safety features like overcharging, overcurrent, and short circuit protection to ensure your devices stay safe during charging. Just make sure you're using a high-quality charging cable! 😉

3. Why should I choose your product over other products?
At Sunny Stores, we prioritize customer satisfaction and exceptional quality. Our power banks offer reliable performance, safety features, and stylish design, ensuring you have the best experience at an unbeatable value.

4. If it's good quality, why is it that cheap?
We believe that great quality shouldn't break the bank. By optimizing our supply chain and keeping overhead costs low, we can offer top-notch power banks at affordable prices. Our focus is to provide an exceptional experience without emptying your pockets! 💰😄

5. How long does it take to fully charge the power bank?
With a 2A charger, it usually takes around 4 hours to fully charge a 10000mAh power bank. For a 20000mAh power bank, the charging time doubles to approximately 8 hours. But hey, you can always binge-watch your favorite series while waiting! 📺

6. Can I charge multiple devices at once?
Yes, indeed! Our power banks come with multiple output ports, allowing you to charge multiple devices simultaneously. Just plug in your devices, and let our power bank take care of the rest. Sharing is caring, right? 🤗

Yes, you can! Our power banks support pass-through charging, allowing you to charge both the power bank and your device simultaneously. It's like a charging party, and everyone's invited! 🎉

9. How long will the power bank hold its charge if I don't use it?
Our power banks have a low self-discharge rate, meaning they can hold a charge for a few months without a significant drop in capacity. However, it's always best to top them up every couple of months to ensure peak performance. Better safe than sorry! 🔋

10. Do your power banks come with a charging cable?
You bet! Each power bank comes with a charging cable, making sure you're all set right from the start. Just plug it into a compatible charger, and you're good to go. Happy charging! ⚡️
