Portable solar power bank

The Jaspertronics PS-157 combines a 20000 mAh polymer lithium-ion battery with a 2 W solar panel in a single unit. It supplies 5 V 2.1 A through three USB ports and offers 5 W wireless charging. A 1 W LED lamp adds illumination for outdoor or emergency use.

Dual input charging

The unit accepts power through both micro-USB and USB-C inputs at 5 V 2.0 A. This flexibility lets you replenish the internal battery from standard wall adapters or compatible cables before heading off-grid. Solar charging provides an additional, slower top-up option in daylight.

Integrated lamp and wireless pad

The built-in 1 W LED lamp serves as a practical light source for camping or power cuts. The 5 W wireless charging pad supports Qi-compatible devices without cables. Both features draw from the same 20000 mAh reserve, so extended use of either reduces capacity available for phone or tablet recharging.

Questions about this item

What does the 20,000 mAh capacity mean for real-world phone charges?

The 20,000 mAh polymer lithium-ion battery stores enough energy to recharge a typical smartphone several times over before the power bank itself needs refilling.

How fast can the USB ports actually charge my devices?

The three USB ports share a combined 5 V 2.1 A output, so each device draws up to that rate depending on how many are connected at once.

What are the exact dimensions and weight so I know if it fits my pack?

The unit measures 173 mm by 85 mm by 26 mm and weighs 465 g net, making it compact enough for a daypack or glove compartment.
