AsperX Power Bank 15,000 mAh portable charger
Product description
This pair of portable chargers offers dependable backup power with enough capacity to charge phones and small devices multiple times during a day out. The AsperX twin pack of 15,000mAh power banks includes USB-C input and output together with two USB-A outputs, so you can keep a phone, a set of wireless earbuds and a tablet topped up while travelling or commuting.
Key Points
Each power bank in this 2 pack has a 15,000mAh rated capacity, which, according to the manufacturer, delivers substantial runtime for modern smartphones and tablets. The inclusion of USB-C for both input and output means the same cable can be used to recharge the bank and to charge USB-C devices, simplifying cables on the go. With two standard USB-A ports available alongside the USB-C port, the units allow charging of up to three devices simultaneously, which is useful when sharing power with friends or keeping multiple items active.
The shell is made from fire-retardant plastic for added safety during use and transit. The charging circuitry is described as recognising connected devices and managing distribution to provide up to 5V/3A output per port collectively, which helps reduce charge times for compatible handsets. Note that the quoted fast-charge figures are based on manufacturer tests and actual results will depend on device model and cable quality.

Benefits
The dual-port layout with a USB-C option makes these power banks flexible for both older devices that still use USB-A and newer kit that uses USB-C. For travellers, the ability to charge multiple items at once reduces the number of chargers and adapters to carry. Carrying two identical banks in the pack provides redundancy; you can leave one in a bag and stash the other in a pocket for longer trips.
Charging speeds are positioned as faster than typical 2.1A power banks, with manufacturer claims showing quicker percentage gains in the first hour on compatible phones. This means less time tethered to the bank and more time using your device. The compact format of each unit is convenient for daily commuting or short overnight stays.
Usage Recommendations
Use the USB-C cable provided to recharge the power bank more quickly and to take advantage of the USB-C output on supported phones and tablets. When charging multiple devices simultaneously, connect the highest-drain device first to ensure the most efficient distribution of power. Consider keeping one bank reserved as an emergency reserve when on longer journeys. Also bear in mind that real-world capacity will be lower than the nominal 15,000mAh due to conversion losses, so expect fewer full phone charges than the raw number suggests.
