Get a Free Fulfillment QuoteCreative Implementation: WINSWAY Opens U.S. Power Bank Market with Crowdfunding Thinking
When the WINSWAY team finalized the design for their first mini capsule power bank, their core value proposition was "zero-burden travel power"—the essence of crowdfunding: precisely capturing user pain points. After surveying the U.S. market, they identified two major issues with mainstream power banks: bulky designs unfit for pocket carry and discrepancies between labeled and actual capacity, leading to "endurance anxiety." To address this, WINSWAY launched key features like "5000mAh/10000mAh ultra-compact capsule design + built-in Type-C cable + dual-device 22.5W fast charging," with chip optimizations for LED digital display and wireless foldable output, targeting business commuters and outdoor travelers. The product line focuses on the "ultra-portable wireless series," expanding from entry-level 5000mAh to premium 10000mAh models.Live on SHEIN, with Q3 2024 sales exceeding 100,000 units and a 25%+ repurchase rate.
In the startup phase, the WINSWAY team knew: Creative ideas require reliable fulfillment to land. Unlike trial-and-error logistics for new ventures, WINSWAY selected WinsBS, a deep-rooted U.S. ecommerce 3PL provider—rich in consumer electronics experience (serving 50+ power bank brands)—as their top partner.
WINSWAY's Core Challenges:
- Lithium battery compliance – Strict UN38.3 certification and FDA warehousing standards posed risks of cargo seizure for non-compliance, complicating U.S. power bank ecommerce fulfillment and delaying launches by weeks.
- New brand trust barriers – Users favored established names like Anker, demanding "zero-damage delivery" to build credibility; early TEMU/SHEIN reviews showed 10% abandonment due to perceived reliability gaps in portable charger logistics.
- Small-batch trial sales costs – Initial 1000-unit runs faced traditional logistics fees of $3+ per unit, squeezing margins to under 15% and hindering crowdfunding-inspired DTC scaling for fast charging power banks.
- These challenges highlighted the need for a professional 3PL to resolve compliance, experience, and cost issues in U.S. DTC power bank fulfillment.
“We needed a 3PL that nailed compliance from the start to build trust fast.”
Fulfillment Synergy: From Standard 3PL to Customized Optimization's "Mutual Empowerment"
A U.S. Warehouse Network with Smart Inventory Allocation
Strategic three-warehouse coverage — WinsBS's Dallas central, Beaverton West Coast, and Carteret East Coast facilities span East, Central, and West regions, delivering 85% of U.S. power bank orders in 3 days for seamless DTC portable charger logistics.
Dedicated lithium battery zones — Constant 20-25℃ temperature and 40-60% humidity, with regular fire drills, ensure 100% UN38.3/FDA compliance, preventing overselling via real-time API integration with SHEIN backend.
Efficiency Gains & Cost Transparency
Packaging upgrades & rapid response — Addressing 8% "easy-to-crush" feedback, WinsBS switched to E-flute rigid boxes + shock foam (50% better crush resistance), branded with LOGO and "safe fast charging" tips, lifting ratings to 99%.
Emergency fixes — For a 23-order "cherry pink" shortage, Beaverton transfers via FedEx priority (WinsBS-covered costs) + $4 built-in cable gifts turned crisis into loyalty, with 17/23 repurchases.
Cost savings — Logistics dropped 15% through pre-stocked hot SKUs in high-repurchase zones (e.g., California/New York) and dedicated TEMU picking channels for 24-hour fulfillment (same-day before 3pm).
Clear optimization — Iterative monthly reviews provided transparent breakdowns, proving no hidden fees when customizing for low-price fast shipping.
Iterative Customization & Scalable Growth
Exclusive scheme evolution — The loop refined standard to bespoke: SKU bundling turned slow "mint green" stock into "travel fast charge kits" (20% off with LED cables), clearing 2000 units and boosting turnover 30%.
TEMU/SHEIN synergy — Compressed timelines and compliance focus slashed first-trial damage rates from 8% to 0.2%, fostering 94% positive ratings and turning users into fans.

Customer Testimonial: Real Voices from Retail Partners
Our first Temu power bank batch arrived after 10 days, with half the cherry pink units dented from poor packaging—customers flooded reviews with 'shipping nightmare' complaints, tanking our 4.2 rating. WinsBS's Carteret East Coast hub flipped the script: Custom E-flute boxes cut damage to 0.2%, and 1-2 day East deliveries turned those headaches into 4.9 stars.
SHEIN syncs used to oversell, leaving us scrambling for refunds. Now, their API flags stockouts 48 hours early, and that one 23-order glitch? Carteret FedEx rush + free cables salvaged it—17 buyers came back stronger, no more 'scam' vibes in feedback.
For DTC upstarts like us, real fixes and fast trust matter. WinsBS makes it happen.

See what our clients say about us
Launching our capsule power banks on SHEIN, packaging crushes were killing reviews—8% returns from dented cherry pink units. WinsBS's Carteret East Coast upgrades to E-flute boxes dropped damage to 0.2%, turning 'shipping fail' complaints into 99% 'perfect arrival' praise.
TEMU peaks used to overwhelm us—4-6 day delays sparked 'slow shipper' backlash. With WinsBS's 24h dedicated channels, East Coast orders now hit 1-2 days, handling 300+ daily surges without a hitch, and boosting our ratings from 4.2 to 4.9.
API glitches once caused 23-order oversells on mint green stock, eroding trust. WinsBS's real-time fixes—FedEx rushes from Beaverton + $4 cable gifts—salvaged it with 17 repurchases, plus 15% cost cuts via transparent bundling, making small trials profitable.
WinsBS × WINSWAY: Just the Right Fit
When WINSWAY began scaling sales of its mini capsule power banks, fulfillment became a breaking point. Previous providers struggled with lithium battery compliance, creating blind spots in UN38.3 certification and inconsistent handling of fragile fast-charging components. With WinsBS, the onboarding process was radically different. The team gave us a walkthrough of their self-operated Carteret facility, showing clear workflows for receiving shipments from our factory, storing in dedicated battery zones, and shipping portable chargers. From day one, we had confidence that stock would be managed safely, without the chaos we experienced before.
Efficiency was the next breakthrough. With WinsBS’s API-driven processes, our pick-and-pack speed tripled, allowing the team to handle seasonal surges like Black Friday without delays. Orders that once took 4–6 days to reach East Coast now arrive in just 1–2 days. During one rush period, they processed over 300 orders in 24 hours, and even issued proactive low-stock alerts 48 hours in advance—giving us time to bundle mint green units before customers felt the pinch.
Cost control also shifted dramatically. Logistics had been eating up nearly 18% of our revenue. WinsBS’s model—with 92% carrier discounts, per-unit storage fees, and AI-optimized bundling—cut that down to just 13.6%. More importantly, every monthly invoice arrived fully itemized, with no hidden charges. When we requested custom E-flute packaging, WinsBS presented side-by-side cost comparisons immediately, making decisions straightforward for our finance team.
Returns, once a liability, became a strength. Power banks returned for fit or inspection are now tested, compliant-checked, and restocked within 3 days. WinsBS even provides photo documentation of any damaged units, helping us track quality issues upstream with the manufacturer. Over the past five months, this process has reduced return-related complaints to zero and improved overall trust with our customers.
Looking back, what makes WinsBS invaluable is not just speed or cost—it’s the innovation and scalability. For a crowdfunding-inspired electronics brand like WINSWAY, every shipment is a chance to reinforce customer trust. WinsBS ensures those promises are kept, making them more than a 3PL—they’re a partner in growth.
WINSWAY’s TEMU mall was packed with international buyers—WinsBS kept samples and follow-up shipments on time, every time.
Showcasing the brand's multi-line production and growth—WinsBS ensures compliant export and turns output into on-time, damage-free deliveries.
