FAQs
How much charge does the 5,000mAh capacity provide?
The 5,000mAh battery typically delivers roughly one full charge for many modern smartphones, or a significant top-up depending on the phone’s battery size and efficiency. Real-world output is usually lower than the rated capacity due to conversion losses.
Does the built-in connector work with phone cases?
Yes, it is designed to work with most phone cases up to about 4.9 mm (0.19 inches) thick. Thicker or bulky cases (such as some rugged OtterBox models) may not fit properly.
Can I charge a device while recharging the power bank?
Yes, pass-through charging is supported. You can power a connected device while the power bank itself is being recharged, though the output power is reduced during this process.
