wongkuo M300 Solar Power Bank, 49,800mAh with Qi Wireless Charging

Some charging setups call for a simple backup, others need to support several devices and offer more than one way to recharge. The wongkuo M300 brings cable-based and Qi wireless charging together in one portable power bank.

Its 49,800mAh lithium-polymer battery provides portable backup for travel, camping, road trips, and power outages. Four built-in output cables help reduce the loose cords you need to carry.

A built-in solar panel offers an emergency charging option when outlets are out of reach. For everyday recharging, the manufacturer recommends using the main input.

Key takeaways

The M300 combines a 49,800mAh capacity with QC 3.0 fast charging and a Qi wireless charging pad. That mix gives you a choice: connect a compatible device with a cable or place a Qi-enabled phone on the wireless pad. Its three ports and built-in cables make it useful for carrying a shared power source for everyday electronics.

The solar panel is intended as an emergency backup, while the main input is the recommended route for faster daily recharging. A solar charging indicator lights when the panel is exposed to sunlight. Overcharge and short-circuit protection are also listed among its features.

A built-in flashlight includes steady, SOS, and strobe modes. Double-click the power button to turn it on or off, then press once to switch modes. The included components are built-in cables, a flashlight, a lanyard, a solar panel, and a user guide. The charger measures 5.7 x 3 x 0.67 inches and comes in red.

How to use it

For routine charging, connect the M300 through its main input, then use a built-in cable or an available port to charge a device. For Qi wireless charging, use a compatible Qi-enabled phone. The built-in cables are handy when you want a charging option close at hand without packing a separate cord for every device.

When an outlet is not accessible, expose the solar panel to sunlight and look for the indicator light to show that solar charging is in progress. Treat this as a backup approach for situations such as a campsite or a power outage, rather than the usual way to recharge the bank. The flashlight’s separate modes also give it a practical role in a travel or emergency kit.

Best use cases

The M300 suits trips where phones, earbuds, watches, or other everyday devices need a shared portable power source. On a road trip, built-in cables can simplify charging between stops, at a campsite, the solar panel and flashlight add useful backup functions. At home, the high-capacity battery can serve as a portable reserve during an outage.

If you prefer a minimal charger for one device and one cable, a simpler setup may better match that routine. The M300 takes a more versatile approach, combining wired charging, Qi wireless charging, solar backup, and a flashlight in one unit.

Buyer feedback is mixed: some customers praise its charging and usefulness, while others report concerns about reliability or charging performance. Those differing experiences make it sensible to consider the feature set alongside your own charging needs.

Is it worth it?

It makes sense if you want a high-capacity power bank that can support both cable and Qi wireless charging, with built-in cables to make packing easier. Its solar panel is an extra backup option for outdoor trips and outages, and the flashlight adds another practical function for those settings. Choose the M300 for a portable, multi-purpose charging kit rather than a basic single-device charger.
