Q
这款PB91移动电源适合旅行使用吗？它可以给我的iPhone 15或Samsung Galaxy充电多少次？
A
当然适合。这款HAVIT型号拥有20000毫安时的大容量，而其机身尺寸仅为137*70*27毫米，非常小巧。这样的电量足以给iPhone 15充电大约四到五次，之后你才需要寻找电源插座。
Q
我可以同时给两个设备充电吗？它们充电速度会变慢吗？
A
可以的。它配备两个USB-A接口，每个接口的输出功率为5V=2.4A，因此你可以同时为手机和平板电脑充电，而不会导致任何设备充电速度显著下降。
Q
这个电池包有安全保护功能吗？我可以把它插在电源上过夜使用吗？
A
是的，该产品配备了全面的保护电路，可以自动防止过电压、过电流和短路情况，并能智能识别连接的设备类型，从而提供最佳的电流输出，而不会以最大功率对所有设备进行充电。
Q
我需要用什么类型的线来给这个移动电源充电呢？
A
你不需要担心这个问题。它支持Micro USB和USB-C两种输入接口，你可以根据家里或办公室现有的线缆来选择合适的充电方式。
Q
这个移动电源是否足够耐用，适合销售团队或送货司机等需要可靠设备的日常使用？
A
它采用ABS材料制成，重量轻，只有384克左右，即使在日常使用或旅行中也能承受一定的磨损。对于B2B买家来说，这种耐用性对于降低设备更换成本非常有价值，尤其是当他们为团队配备大量设备时。
