Massive 50000mAh capacity

The Seaistar P500 power bank stores 50000 milliamp_hours in a lithium-polymer cell, delivering up to 11 full charges for an iPhone 13 Pro and 8 charges for a Samsung Galaxy S22. Most smartphones receive over 9 complete recharges, making the unit practical for extended camping trips, long-haul travel or multi-day power outages.

Four outputs and dual inputs

Four USB-A ports and one USB-C port allow up to four devices to charge at once, while the USB-C and Micro-USB inputs let you replenish the bank itself. A 5V 3A charger refills the pack in about 8 hours, and PD 30W output pushes an iPhone to 61 percent in 30 minutes. The built-in LED display shows the exact remaining percentage for easy power management.

Suits heavy multi-device users.

Campers, families and mobile professionals who need days of reserve power for phones, tablets and small laptops will benefit from the high capacity and simultaneous charging. Buyers who want a pocket-sized emergency top-up or the absolute fastest single-device charging speeds should look at smaller, higher-wattage alternatives.
