Solar Power Bank, 20000mAh, Hand Crank, 15W Wireless, Laser SL-908
Product Overview
Designed for the case where the sun does not cooperate. Alongside the 5.5 V/1.5 W solar panel, this 20000 mAh pack carries a fold-out hand crank rated 5.5 V/500 mA - about 400 mAh for an hour of turning - so it can still deliver power after days without sun or mains. The front face runs a three-in-one wireless charging coil at up to 15 W that also serves earbuds and watches, while the 22.5 W main controller pushes 10 V/2.25 A and 12 V/1.67 A through USB-A. Four cables are built in, and a 650 nm 5 mW laser pointer sits next to the 2 W work light for pointing and signalling. The 184 x 89 x 35.5 mm housing weighs 615 g and is built for vehicle, patrol and disaster-response kits.

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
Frequently Asked Questions
How much power does the hand crank actually produce?
About 400 mAh per hour at a steady 120 rpm, at 5.5 V/500 mA. It is an emergency reserve rather than a routine charging method, which is why the solar panel and mains input are there.
Which devices does the wireless pad support?
Phones at up to 15 W, earbud cases at 5 W and smartwatches at 1.5 W, all on the same three-in-one coil.
Is the laser safe for consumer sale?
It is a 5 mW Class 3R 650 nm module. Tell us your destination market and we will confirm the labelling and documentation that market requires.
What is your minimum order quantity (MOQ)?
Our MOQ is 100 units for most power bank and speaker models. Selected items can start from as low as 2 units, so retailers and startups can test the market before scaling. Mixed orders across our product categories are accepted.
Can you provide OEM/ODM or private label services?
