Built for outdoor use

The PS35K is a 20000mAh lithium-ion power bank wrapped in eco-friendly silicone rubber and ABS PC material. It carries CE, FCC and RoHS certifications and features drop-proof, dust-proof and water-proof construction with thick silicone corners and a covered charging port. Campers, hikers and anyone working in harsh environments can rely on its rugged housing for daily power needs.

Steady output across six devices

The unit delivers a consistent 5V 2.4A supply through three built-in output cables — USB-C, Lightning and Micro-USB — plus a USB-A input cable and two additional ports (USB-C in/out and USB-A out). This arrangement lets you charge up to six smartphones or a tablet simultaneously without hunting for extra cables, making it practical for group trips or multi-device workflows.

Compact profile with dual flashlight

At 5.9 in x 3.14 in x 0.78 in and 250 grams, the bank fits easily in a pack while the integrated solar panel provides supplementary charging; a green LED confirms solar input and a blue LED shows USB charging. Two LED lights offer steady, SOS and strobe modes for illumination, and five pilot indicators display remaining capacity at a glance.

Questions about this item

How much heat or noise does the PS35K produce when it is charging multiple devices all day?

The power bank has no fan or moving parts, so it runs silently and generates only minimal warmth during extended use.

What cables or adapters must I already own to use the PS35K with my phone?

Nothing extra is needed — the unit includes built-in Type-C, Lightning and Micro-USB output cables plus a USB-A input cable.

Will the PS35K charge properly from an older USB-A wall charger I already have?

Yes, the USB-A input cable accepts 5 V / 2.4 A from legacy chargers, though charging the 20000 mAh cell will take longer than with a Type-C source.
