Product description
For campers who need backup power away from an outlet, the Luvknit PS31H combines a 20,000mAh battery with several ways to connect devices.
Built-in USB-C, Lightning, and Micro-USB cables help keep charging simple when you’re traveling with different devices.
A wireless charging pad, USB output, and emergency flashlight add useful options for a campsite or day outdoors. Solar charging is intended for emergency top-ups, charge the power bank from a wall outlet before your trip.
Technical overview
The PS31H has a maximum output of 15W and supports wired and wireless charging. Its built-in cables cover common connector types, so you can charge without packing a separate cable for each one. The USB output provides another connection option, and the power bank is designed to charge up to five or six devices at once.

The integrated LED flashlight offers Strong, Strobe, and SOS modes. Press and hold the power button for three to five seconds to turn it on or off, a single click cycles through the modes. The unit can handle light splashes, but it is not waterproof, so keep it out of heavy rain and do not submerge it.
For solar use, treat the panel as an emergency backup rather than the main way to recharge: solar charging is very slow. Before leaving, fully charge the power bank using a wall adapter and cable. For first use, the instructions recommend charging with a 5V/2A wall charger for at least six to eight hours to activate the cells.
Everyday use
At a campsite, the built-in cables can serve a phone with a matching connector, while the wireless pad gives a compatible phone another way to charge. With multiple output options, the pack can also help when a group is carrying devices with different charging needs. Its 5.63-inch length and compact rectangular shape make it practical to pack alongside other trip essentials.
Compared with a basic power bank that relies on a single port and separate charging cables, the PS31H brings several common connections and wireless charging together in one unit. That can make it useful for travel or shared outdoor use, especially when you want fewer separate cables to organize. Buyer feedback is mixed on charging speed, solar performance, and build quality, while portability and compact size receive positive mentions. The solar panel is best treated as a backup for emergencies, not a dependable replacement for charging before departure.
Box contents
The package includes one solar power bank, one carabiner, and a user guide. The carabiner offers a way to attach the unit to gear when packing for an outdoor outing.
Final verdict
The Luvknit PS31H suits camping and travel plans that call for a high-capacity backup with flexible charging options. Its three built-in cables, wireless charging pad, USB output, and multi-mode flashlight bring practical functions together, charging it fully before you leave lets you rely on its stored power, with solar reserved for emergency top-ups.
