35W Laptop-Charging Solar Power Bank, 20000mAh, 15W Magnetic Wireless SL-602
Product Overview
The SL-602 is the outdoor pack that can still charge a laptop. Its Type-C1 port runs 5V to 20V at up to 35W, which is enough for a thin-and-light notebook, while a second Type-C and a USB-A port split the remaining load across a phone, a tablet and a camera. The top face is a 15W magnetic wireless pad, so a phone can be dropped on and charged without a cable, and a 3W LED on the side handles campsite light with SOS and strobe modes. A 9V/1.5W solar panel on the back trickles charge back in during the day, and mains refill takes about five to six hours. The housing is waterproof, dustproof and wrapped in a textured shell that stays put in a wet hand, with a lanyard loop at the corner. Four colourways are available.

Product Details
OEM & ODM Services
Casun has built power banks in Shenzhen since 2011, and the SL-9 series is our own outdoor platform rather than a bought-in shell. For this model we offer custom logo, custom shell colours, retail gift box and master carton design, cable and port configuration changes, and capacity or panel variants on volume orders. Seven in-house engineers handle PCBA and structure design, so a custom version is a normal production run.
- MOQ 100 pcs for standard colours, mixed models accepted
- Samples in about 5-7 days, bulk production in 15-25 days
- Trade terms EXW, FOB, CIF or DDP; T/T 30% deposit, 70% before shipment
- 12-month warranty against manufacturing defects
