Optional: select one or more cards to note your interests.
Dashcams, car stereos and navigation systems, portable navigation devices (PNDs), and CarPlay devices with a memory card slot.
Audio players, speakers, smart and AI toys, children’s learning devices and other consumer electronics that use memory cards.
Other applications
For other equipment, include the device and operating conditions in your enquiry.
Capacity range
Find a capacity range for your devices.
Our core range covers 2GB–256GB. The amount of content and the capacities supported by your device help narrow the choice.
Music, voice prompts and preloaded stories often fit a smaller card. Start with the size of the content library.
Suggested starting range2GB–16GB
Recording, content-heavy vehicle systems and Android devices may need more space for footage, maps or media.
Suggested starting range16GB–256GB
Speed is a separate choice. Class 6 / Class 10 (C6 / C10) options can suit audio and file playback; Ultra High Speed (UHS) Speed Class 1 / 3 (U1 / U3) options are available for suitable recording configurations. The capacity range is a starting point; the device and recording requirements determine the final combination. speed-class guide · recording capacity planner.

Cost & write endurance
What matters most for your order?
Tell us how you would like to balance purchase cost, everyday performance and write endurance — the ability to withstand repeated writing.
Keep purchase cost at the centre of the discussion. Start with the capacity and performance your device needs, especially when content is read more often than rewritten.
Your focusMeet the essentials within budget
A practical choice for everyday use. Weigh price alongside the performance, consistency and writing workload your product needs.
Your focusBalance product needs and price
Give repeated writing a larger share of the budget. Discuss configurations suited to more frequent rewrites, with a potentially higher purchase cost.
Your focusPrioritise repeated writing
One-year warranty support. YOULEN cards have a one-year warranty, including cost-focused options. We confirm the coverage and claim process for your order.
These purchasing priorities help us shape the configuration for your order. For hot or outdoor environments, especially in-vehicle and industrial applications, share the operating conditions with us. We will review the temperature and writing requirements with you to confirm a suitable configuration. write-endurance guide.
Card face
Choose the card face for your business.
YOULEN branding, an unbranded presentation or your own printed logo can support device projects, retail or distribution. The card face is a presentation choice, separate from the card specification.

Use the existing YOULEN card design for your equipment or sales channel.

A neutral presentation when you do not need a brand logo on the card.
Discuss private-label printing and artwork approval for your brand. Confirm the product and order conditions with our team.
Packaging
Choose packaging for your sales channel.
From handling cards on an assembly line to distributing individual units or displaying them in a shop, packaging follows your sales and delivery channel.

For device assembly: keeps cards together for batch handling or installation.

For distributors: supports individual-card handling and onward delivery.

For retail display: gives a shelf-ready presentation.

Want to know more about your order?
How many cards can I order?
Custom card printing starts from 500 cards. This depends on the card, design and order requirements.
For bulk orders without custom printing, tell us the quantity for each capacity. Mention any mixed capacities or custom packaging. We will confirm the available options and quote for your order.
What do you need to print my logo?
Please provide documents showing that you can authorize us to use the logo. We confirm this first, then agree the design with you.
You can send your own artwork. We can also help with simple designs for the card face and printed packaging card.
Capacity and speed markings must match the selected card. We also check the licensing requirements for any SD/microSD logos and performance marks in your design.
How can I tell different card options apart?
Printed capacity and technical markings usually help identify the card. But cards with the same capacity and speed markings may have different write endurance.
We add identifying marks where needed. Different quality options are packed separately and clearly labelled. You can also send us a card’s laser-engraved code so we can look up its details.
Need a different number of cards and packaging units? List both quantities and which card each pack is for. We will confirm the packing arrangement.
How do I order samples, and what do they cost?
Tell us which card you want to test. If you need help choosing, send the device model. Include the sample quantity and delivery address.
We will confirm the sample charge, shipping cost and estimated dispatch date. Tell us if the test also needs custom printing, packaging or preloaded files. Sample arrangements are agreed separately from the bulk order.
How do you match a bulk order to my approved sample?
Every YOULEN card has a laser-engraved code. Keep your approved sample’s code and test record. We can use them to look up the sample configuration and test information when confirming your bulk order.
Need the same flash memory, controller or firmware in future orders? Tell us before sample approval. We will confirm whether we can support this and agree the terms. A traceable sample does not, by itself, guarantee unchanged components.
See the device-testing checklist and blank test recordCan I use Alibaba Trade Assurance or my freight forwarder?
Tell us how you prefer to order and where the goods should go. Mention if you want Alibaba Trade Assurance or delivery to a freight forwarder in China.
We will confirm whether this is available for your order. The order confirmation will state the handover location, who handles transport and export clearance, and the related charges.
