NEWS CENTER

Wired vs Wireless Power Banks: Pros and Cons

Wireless power banks become trendy with magnetic wireless charging for Qi-compatible phones. They let users charge without plugging in cables, very convenient for quick top-ups. But wireless transfer has lower efficiency.

Custom Power Banks: Great Promotional Gifts

Custom printed power banks are one of the most popular promotional gifts for exhibitions, corporate events and brand marketing. Supports can print your logo, slogan or brand pattern on the shell. Many models accept custom packaging with low MOQ. They are practical gifts, not useless trinkets. Every time recipients charge their phones, they see your brand.

Multi-Port Power Banks: Charge Several Devices Together

Multi-output power banks are popular among users who own many digital gadgets. Most designs combine USB-A and Type‑C ports, and premium versions add wireless charging coils.

FAQ

How long does it take to fully charge this power bank?

+

The charging time depends on your charger’s output. Using a 5V/2A adapter, it usually takes around 4–6 hours for a full charge. If you use a PD fast charger, the charging period will be shorter. We suggest using a certified charging adapter for better safety and efficiency.

Can this power bank charge multiple devices at the same time?

+

Yes. It is equipped with USB-A and Type-C dual output ports, which support charging two devices simultaneously. The power bank will automatically distribute the output current reasonably to protect your phones, earbuds or cameras from unstable power supply.

Is this power bank safe for air travel?

+

Yes. Its capacity meets airline regulations. You can carry it in your carry-on luggage, but it cannot be checked in. Please note that damaged or swollen power banks are not allowed on the plane for safety reasons.

Why can’t the power bank charge my phone?

+

Please check several points: confirm the power bank has remaining power, make sure the cable and port are not loose or damaged, and verify that your device does not have special charging restrictions. Try replacing the charging cable first, which solves most connection issues.
