Two-pack 20000 mAh portable chargers

This set contains two 20000 mAh lithium-ion power banks, each rated at 74 Wh and 22.5 W maximum output. They are intended for users who need multiple high-capacity banks for phones, tablets or earbuds during travel, commutes or extended periods away from mains power.

Users needing simultaneous multi-device charging

The dual USB-A ports and single USB-C port on each bank allow up to three devices to charge at once, which suits households or individuals carrying several gadgets. Buyers who only need a single lower-capacity bank for occasional top-ups, or who require higher wattage for laptop charging, should look at something else.

22.5 W peak output with USB-C bidirectional port

Each unit delivers up to 22.5 W through its USB-C port, which also serves as the input for recharging the bank itself; compatible smartphones can reach roughly 55 percent charge in 30 minutes.

Questions about this item

What are the physical dimensions and weight of each 20000 mAh unit in the pack?

The two-unit pack weighs 0.871 kilograms total and each power bank is rated at 74 watt-hours, meeting typical carry-on limits.

How do I recharge the power bank and which port do I use for the fastest input?

Use the USB-C port with a PD charger; the same port handles both input and output so you only need one cable to refill the bank.

After how many charge cycles or months will the battery capacity noticeably drop?

The manufacturer rates the life cycle at 18 months; capacity will gradually decline after that period under normal use.
