FAQ
Product
When selecting a power bank, consider the following key factors:· Capacity: For phones, a power bank with a capacity of around 10,000mAh is suitable, while laptops may require one with 20,000mAh or more. The capacity determines how many times you can charge your device on a single charge of the power bank.· Ports and Compatibility: Check if the power bank has the ports you need, such as USB-C, USB-A, or Lightning, to ensure it can connect to your devices without requiring additional adapters.· Charging Speed: Look for power banks that support fast charging technologies like Quick Charge or Power Delivery, which can significantly reduce charging time for compatible devices.· Size and Weight: Consider the portability of the power bank. If you plan to carry it frequently, a compact and lightweight design may be more convenient, though larger capacities may require a trade-off in size and weight.· Safety Features: Prioritize power banks with built - in protections against over - current, overheating, and short circuits to ensure the safety of your devices and the power bank itself. For example, if you need a reliable and powerful portable power source for multiple devices, INIU Cougar P64-E1 Power Bank is an excellent option. It boasts a massive 25,000mAh battery capacity and supports blazing-fast 140W charging—simultaneously power a MacBook Pro 16" to 60% and an iPhone 15 Pro Max to 62% in just 30 minutes.
The lifespan of a power bank depends on several factors—including its build quality, battery type, capacity, and how you use it. On average, most last 300-1,000 full charge cycles (roughly 1.5 to 3 years of typical use). INIU offers a 3-Year Care warranty on all products—the longest in the market, delivering a reliable and long-lasting charging experience.
The charging time for a power bank depends on its capacity and the input charging speed. For instance, a 10,000mAh power bank typically takes about 4-6 hours to fully charge using a standard 5V/2A charger. Be sure to use the right charger to avoid slow charging. With USB‑C PD input, high‑capacity banks can recharge in 2-3 hours. Be sure to use the right charger to avoid slow charging.
Wireless power banks utilize electromagnetic induction to transfer energy from the bank to a compatible device, without having to plug in a cable. Qi2 is the latest standard in wireless charging technology, delivering up to 15W of power and employing magnetic alignment to improve charging speed. For instance, INIU SnapGo P73-E1 Wireless Power Bank, featuring Qi2-Certified 15W wireless output, charges 2X faster than standard 7.5W chargers.
Yes, many power banks feature multiple output ports (USB‑A and USB‑C) for simultaneous charging. Higher-end power banks provide balanced power distribution, enabling you to charge both a phone, tablet and laptop at once without performance loss. One excellent option is INIU Cougar P63-E1 Power Bank, delivering up to 100W to high-performance laptops and 45W to daily smartphones—simultaneously supporting up to 3 devices.
