Solar Power Bank, 20000mAh, Hand Crank, 6W Solar Panel SL-916
Product Overview
The fastest solar recharger in the range. A 5.5 V/6 W panel covers the back of this 20000 mAh pack, several times the surface area of the pocket models, so a day in the sun makes a meaningful contribution rather than a token one. A fold-out hand crank adds another route at 5.5 V/400 mA, roughly 400 mAh per hour, and mains input over Type-C at 5 V/2.6 A fills the two 1260110 cells in 8 to 9 hours. Output runs through Type-C and USB-A at 5 V/3 A plus four built-in cables, and a three-in-one wireless pad covers phones, earbuds and watches at up to 5 W. The 185 x 92 x 48 mm housing weighs 792 g, which suits vehicle kits, site cabins and emergency stock rather than a pocket.

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 does the 6 W panel actually add?
At full sun the 5.5 V/6 W panel delivers roughly 1 A into the pack, so a clear day outdoors can make a meaningful contribution. Output falls off in cloud or shade, which is why the hand crank and mains input are also provided.
What is the hand crank for?
It is an emergency route: about 400 mAh per hour at 120 rpm, enough to make a call or send a message when nothing else is available.
Which devices can charge wirelessly?
Phones and earbud cases at 5 W and smartwatches at 1.5 W through the three-in-one coil. This model is a 5 W wireless class, not a 15 W fast wireless unit.
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?
Yes. As an Alibaba.com certified Custom Manufacturer we provide full OEM and ODM support: custom logo, packaging, colors, graphic design and product development. Our 7 R&D engineers handle PCBA design through final assembly, and free samples are available on most models for evaluation before bulk orders.
What certifications and quality control do you have?
We are ISO 9001 certified. Products comply with CE, RoHS, FCC, KC and EN 62479, and our power banks are Qi wireless charging certified. Every batch passes incoming material inspection, in-line QC and final inspection before shipment. Social compliance is verified by BSCI and Sedex.
What is your lead time and production capacity?
Sample lead time is typically 5-7 days. Bulk production usually takes 15-25 days depending on quantity and customization level, and can extend to 30 days for complex custom work. Our factory runs 3 production lines with an annual capacity of 700,000 units and a 99% on-time dispatch rate.
What are your shipping and payment terms?
We support EXW, FOB, CIF and DDP for most destinations, shipping by sea, air or express (DHL/FedEx/UPS). Payment terms are T/T with 30% deposit and 70% balance before shipment, and Trade Assurance covers product quality and on-time delivery.
What warranty and after-sales support do you offer?
All products carry a 12-month warranty covering manufacturing defects. We provide free replacement parts or repair guidance within the warranty period, and our team typically responds within 2 hours.
