High-capacity portable power
The ViewSonic N20 stores 50000mAh of lithium-polymer energy in a carbon-black shell that measures 1.0 x 1.5 x 2.0 inches and weighs 200 g. It delivers up to 22.5 W through a USB-C port, a USB-A port and integrated USB-C and Lightning cables. Four devices can draw power at once, making it suited for phones, tablets, earbuds and small laptops during travel or emergencies.
Sustained output behaviour
Rated at 3.7 V and 22.5 W, the bank maintains fast-charge speeds across multiple ports until the internal cells deplete. The LED percentage display lets you track remaining capacity in real time so you can plan recharges before the power runs out. Built-in protection circuits guard against overcharge, overcurrent, short-circuit and overheating during extended sessions. Airline restrictions apply to this capacity.
Pre-purchase checklist
Confirm that your devices accept USB-C or Lightning connectors and support PD 3.0 or QC 3.0 for the advertised 30-minute charge rate. Verify that 50000mAh exceeds your airline's carry-on limit if you intend to fly with it. Ensure you have a compatible USB-C charger to replenish the bank itself at full speed.

Questions about this item
Does the 50000mAh battery generate noticeable heat when charging four devices at 22.5W for hours?
The lithium-polymer cells and multiple protection systems guard against overheating during extended multi-device charging.
Which cables do I need to supply myself to use the USB-C input/output and USB-A ports?
The unit includes built-in USB-C and Lightning cables; you only need to provide cables for the separate USB-C and USB-A ports.
Will the 22.5W output and PD3.0/QC3.0 support charge an older phone that only accepts 5W?
Yes, the power bank negotiates the safe rate automatically, so legacy devices draw only the power they support.
