Q1 How does your factory handle quality control?
Quality is our priority. We attach great importance to quality control from start to finish. Our production processes have gained CE, FCC, and ROHS certifications.
Q2 Can I have my logo printed on the power bank?
Yes. If you provide your logo file in AI or PDF format, we can prepare a digital artwork mockup for your approval before production.
Q3 How long does it take to charge via solar energy?
Solar charging is intended as a backup emergency solution rather than a primary power source due to the limited size of the solar panel. For daily use, we recommend charging via a wall outlet.
Q4 Is this solar power bank safe for air travel?
Yes, the 20000mAh capacity typically falls within the international aviation limits (under 100Wh) for lithium-polymer batteries in carry-on luggage.
Q5 How many devices can it charge at once?
The device features dual USB output ports plus wireless charging capabilities, allowing you to charge multiple devices simultaneously.
Q6 What are the shipping options available?
We offer shipping via DHL, UPS, EMS, FEDEX, and TNT (approx. 5-8 days) or via airfreight. Sea freight options are also available for bulk orders.
