Solar Power Bank, 30000mAh, 15W Wireless, 4-Fold Solar Panel SL-907
Product Overview
The high-capacity option in the range: 30000 mAh split across three 8870129 cells, with a four-panel solar array that folds out from the body. That reserve covers a week of phone use, or several charges of a tablet or action camera, which is the point for expedition, marine and field-service buyers. Output is fast rather than merely present - USB-A reaches 5 V/4.5 A and 12 V/1.5 A, Type-C covers 9 V/2.22 A and 12 V/1.67 A, and the wireless pad runs up to 15 W. Four cables are built in, and a 2 W LED handles lighting. The housing is textured for grip and rated for 740 g, and a full mains charge takes 6 to 8 hours.

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 many times can it charge a phone?
30000 mAh typically covers six to seven full charges of a 4000-4500 mAh phone, depending on cable losses and charging speed.
Can it charge a tablet or laptop?
It handles tablets and USB-C devices that accept 12 V/1.67 A. It is not a laptop-class supply for models that require 45 W or more.
What is the solar panel for?
The four-fold panel is a maintenance charger: it slows self-discharge and adds range during multi-day trips. Mains charging at 6-8 hours is the fast route.
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.

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.
