In order to charge at 140W, you must be using a cable and device which support USB PD 3.1, a charging standard which was introduced in 2021.
Additionally, charging speed may vary due a number of factors, including how full the device being charged’s battery is, whether other devices are connected and their operating temperature.
Many laptops do not support charging speeds above 60-70W.
Please note that Ark’s battery will drain faster while the screen is active.
Like other lithium-ion power banks, Ark must be disposed of at special collection points for safe processing.
Please consult your local authorities, or the retailer you purchased your power bank from, for the correct way to dispose of power banks like Ark.
• Overcurrent protection
• Overvoltage protection
• Short-circuit protections
• Fire-retardant materials
• High-temperature protections
• Interference protections
Like all personal power banks, Ark cannot be stored in checked luggage.
While the vast majority of airlines follow these guidelines, it remains at the discretion of individual airlines whether lithium-ion power banks are permitted.
• How much charge the battery has.
• The current charging/input speed of all Ark’s USB ports
• How long it’ll Ark’s battery to charge or run out at the current speeds
• How long Ark has been in operation
• The battery’s current maximum capacity, as a percentage of its initial maximum capacity. This is very useful for monitoring Ark’s overall health.
• The current temperature of Ark’s battery cells.
• The percentage Ark’s battery was last charged to
• The number of full battery cycles your Ark has had
• The total charging your Ark has done across its lifetime, measured in watt-hours
This will result in speeds of up to 22 watts for your phone, and the remainder of Ark’s 140W for your laptop.
If you need to use both USB-C ports at once, their maximum speeds will both drop to 65W, which may not be enough to charge some high-power laptops.
