Product description

Why is my power bank providing fewer charges than expected?

Due to approximately 35% energy dissipation at the cell and converter level during charging, the 20000mAh power bank provides about 13000mAh of usable capacity. Rated capacity: 13000mAh (5V/3A).

Why does the charging power gradually decrease while recharging?

When the power bank is recharging, its input power may gradually decrease to prevent overheating and protect the battery. For best results, use it in a cool, ventilated environment (32 – 77°F) and avoid charging other devices at the same time.

Is it allowed on airplanes?

Yes, JUOVI 65W 20000mAh power bank meets the regulations of TSA(Transportation Security Administration) for carring board(≤100wh≈27,027mAh).

Why does the power bank drain quickly when charging a laptop?

When charging a laptop, the power bank operates at high output which slightly reduces efficiency. Laptop batteries are also much larger than phone batteries, so the laptop’s battery percentage rises slowly, making the power bank seem to drain faster.
