Solar Power Bank, 20000mAh, 15W Wireless, 3-Fold Solar Panel SL-905
Product Overview
Built for buyers who need power where there is no socket. The 20000 mAh bank opens into a three-fold solar array rated 5.5 V/1100 mA, so the pack can trickle back up during a multi-day hike, a site job or a festival. Four charging cables are moulded into the body - Type-C, Micro USB, Lightning and USB-A - and the top face carries a 15 W wireless pad, which means six devices can be topped up without a single loose cable. Output supports PD 22.5 W fast charging on compatible phones, and the 2 W ten-LED panel works as a torch or a work light. The shell is dust-proof and splash-resistant with a textured anti-slip finish, and a hanging buckle lets the pack strap to a backpack. Fully charging over mains takes 9 to 10 hours.
Key Features
- 20000 mAh reserve - Enough for roughly four phone charges, with a five-step LED capacity indicator.
- Three-fold solar array - A 5.5 V/1100 mA folding panel that packs flat against the body and opens to catch more light.
- 15 W wireless charging - A Qi pad on the top face charges phones and earbud cases with no cable at all.
- PD 22.5 W output - Fast charging for compatible Android and iPhone models over the built-in Type-C cable.
- Four built-in cables - Type-C, Micro USB, Lightning and USB-A are moulded in, so the pack travels alone.
- 2 W ten-LED light - A wide flood panel that doubles as a tent light or an emergency work light.
- Outdoor housing - Dust-proof, anti-slip textured shell rated for 0-45 degrees C operation.
- Hanging buckle - Clips the pack to a backpack strap or tent loop while it charges.

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 long does the solar panel take to charge the bank?
The panel is rated 5.5 V/1100 mA, so it is a maintenance charger rather than a fast one - it is designed to top the pack up over a day outdoors. A mains charge takes 9 to 10 hours for a full cycle.
How many devices can charge at once?
Up to six: two USB-A outputs, the Type-C output, the built-in cable set and the 15 W wireless pad.
Is it waterproof?
The housing is dust-proof and splash-resistant, which covers rain spray and wet hands. It is not designed to be submerged.
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.
