4smarts UltiMag Portable Battery 20000 mAh
The 4smarts UltiMag Portable Battery 20000 mAh is a high-capacity power bank designed to keep smartphones, tablets and other USB-powered devices charged during travel, work or daily use. With a 20000 mAh Lithium Polymer (LiPo) cell, multiple output ports and support for Quick Charge 3.0, it provides a combination of capacity and fast-charging capability in a compact, pocketable housing. The model also includes wireless charging functionality and a total output power rating that supports modern mobile devices.
The portable battery offers a large 20000 mAh capacity that delivers multiple full charges for typical smartphones and extended runtime for tablets and accessories. Quick Charge 3.0 support accelerates charging of compatible devices through the USB Type-A ports, while the USB Type-C port provides flexible two-way connectivity for input and output. Wireless charging adds cable-free convenience for Qi-compatible phones. The unit is supplied in sleek color options and combines safety features typical for LiPo-based power banks with useful output current levels up to 3 A.
Charge the power bank via the USB Type-C input using a compatible USB power adapter until the internal indicators show a full charge. To charge a device, connect it with a USB cable to one of the USB Type-A or USB Type-C outputs, observing the correct orientation for connectors. For wireless charging, place a Qi-compatible device centrally on the wireless pad. If the connected device supports Quick Charge 3.0, the power bank will negotiate higher charging voltage and current automatically when using the appropriate USB Type-A cable and compatible device.
Use a certified USB cable and a suitable wall adapter when recharging the power bank. Avoid exposing the battery to excessive heat or moisture and store it in a dry place when not in use. For optimal battery longevity, avoid keeping the power bank fully discharged for long periods and recharge it periodically if stored.
