Application Scenarios
1. Emergency Kits & Household Backup Products
The HT-238 combines AM/FM reception, an LED flashlight and three charging routes in a compact body, making it a practical component for household preparedness assortments and backup-power product ranges. This makes it a practical solar crank emergency radio option for distributors and preparedness suppliers.
Suitable for: Emergency kit suppliers, home-preparedness brands, general merchandise importers and distributors.
2. Outdoor, Camping & Off-Grid Assortments
For camping, road trips and locations where mains power is not always available, the built-in solar panel and hand crank provide supplementary ways to recharge the internal battery. Its 223 g body also supports portable use.
The AM/FM receiver and integrated flashlight allow buyers to position the HT-238 as a compact multi-function item within outdoor and travel product lines.
Suitable for: Camping brands, outdoor wholesalers, travel-accessory distributors and sporting-goods retailers.
3. Private Label & Promotional Programs
The HT-238 can be supplied for OEM and private-label programs with buyer-specific branding, color, battery capacity, packaging, manuals and labeling discussed before production.
Suitable for: Importers, retail chains, promotional-product buyers, consumer-electronics brands and private-label programs.
What we can do for our customers?

1. From HT-238 Requirement To Production
For HT-238 projects, we begin by confirming the buyer's sales market, required quantity and the product configuration needed for that channel. The objective is to define the commercial version before sampling rather than making changes after mass production begins.
Customization can cover visible branding as well as practical order details such as housing color, rechargeable-battery capacity, retail box artwork, multilingual manuals, barcode labels and accessories.
The following workflow is used to move an HT-238 inquiry from requirement confirmation to shipment.
Define the HT-238 Configuration
Share the destination market, expected order quantity and the configuration you need. Product photos, a reference specification, packaging artwork or a short requirement list can be used as the starting point.
Confirm Feasibility & Commercial Details
Our team checks which requirements can be applied to the HT-238 and confirms the proposed configuration, customization scope, estimated pricing and production considerations. Initial project feedback is normally provided within 24 hours.
Build the Evaluation Sample
Once the configuration is agreed, an evaluation sample can normally be prepared in about 5 days; customized artwork or structural changes may require additional time.
Buyer Review & Final Confirmation
The buyer can evaluate reception, charging, lighting, appearance and packaging requirements before the production version is frozen. If changes are needed, they are reviewed before the bulk order proceeds.
Produce the Confirmed Version
After sample approval and order confirmation, the HT-238 enters scheduled production, including electronic assembly, product assembly, functional checks, aging procedures and final inspection.
A typical bulk-production cycle is around 30 days, subject to quantity, customization content and the factory schedule at the time of order.
Final Check, Packing & Dispatch
Completed units are checked against the confirmed order requirements before packing. Production or inspection photos and supporting documents can be supplied on request where applicable.
Standard export packing is available. OEM projects may also use customized color boxes, manuals, labels, barcodes and shipping marks according to the approved artwork.
Standard MOQ: 500 PCS. We recommend approving an HT-238 sample and all packaging details before releasing a customized order for mass production.

2. Export Packing & Lithium-Battery Shipping Support
Each HT-238 is protected with a bubble bag and packed in its individual box before the units are arranged in the export carton.
For bulk export orders, the packing method is intended to limit movement during warehouse handling, stacking and international transport while keeping the product, accessories and retail packaging protected.
Because the HT-238 uses a rechargeable lithium battery, buyers and freight forwarders may also require battery-related transport documentation before shipment.
Documents for Air and Sea Shipments
According to the confirmed battery configuration and shipping method, Hai Tong can coordinate the applicable supporting documents for air or sea transport.
- UN38.3 Test Documentation
- MSDS (Material Safety Data Sheet)
- Air Transport Report / Certification
- Sea Transport Report / Certification
Document availability is confirmed against the final product and battery specification. If a buyer or nominated forwarder requires additional paperwork, the requirement can be reviewed before shipment.
Project Experience Relevant to Emergency Radio Buyers
European Emergency-Radio Replenishment – 50,000 Units
A long-term European consumer-electronics customer requires environmental compliance across key materials and components, including the casing, PCB, solder and wiring. The project also specified batteries with temperature monitoring and protection functions for charging and discharging conditions.
When the 2025 power outages in Spain and nearby markets increased emergency-radio demand, the customer placed an additional 50,000-unit order. Hai Tong coordinated materials, production, testing and packing within a one-month window, with finished goods sent by air in batches of up to 10,000 units to shorten replenishment time.



Japanese Preparedness Project – Reliability-Focused Validation
For a Japanese household emergency-kit project, the buyer focused on whether stored radios would remain dependable when eventually needed. Evaluation therefore covered reception sensitivity, battery operation, hand-crank generation, structural integrity, controls, lighting and longer-term operating stability.
Before mass production, validation was carried out to the customer's requirements, including a 1.2 m drop test, 500 hand-crank durability cycles and environmental testing from -10°C to 50°C. Core reception, lighting and charging functions were also checked for batch consistency, followed by production and delivery of 50,000 units.

Long-Term Government Supply Program – More Than 800,000 Radios
Between 2011 and 2013, Hai Tong supplied the HT-777, HT-999 and HT-555 series for an Afghanistan government emergency-preparedness program.
The program ran across three years and involved several radio models rather than a single shipment. Cumulative deliveries exceeded 800,000 units, requiring repeated production planning and stable supply over an extended procurement cycle.
This experience is relevant to buyers evaluating Hai Tong for larger programs because it demonstrates multi-model production management, repeat-batch consistency and the ability to support sustained high-volume orders.
