Products Key Features
Integrated Dual-Connector
Two plugs, one 24.9 g body
A USB 3.0 Type-A port and a USB-C port are integrated into a casing measuring 72.91 × 16.97 × 9.90mm and weighing 24.9 grams, meaning a single storage device can replace both a USB stick and an OTG adapter. Files can be transferred directly from a mobile phone to a laptop – no data cables, no cloud uploads and no need to worry about losing adaptors. The rotating design fully covers both ports when closed, eliminating the need to remove easily misplaced protective caps.


Up to 100 MB/s read on USB 3.0
The USB 3.0 OTG flash drives manufactured by Fondatop are extremely fast: with write speeds of up to 30 MB/s and read speeds of up to 70 MB/s. At a speed of 100 MB/s, a 4 GB video file can be transferred in approximately 40 seconds, whereas a USB 2.0 flash drive would take several minutes. Backward compatibility with USB 2.0 ensures that older office equipment can still be used without any issues.


A-grade original NAND, five-stage test flow
Each batch of products utilises Grade A original NAND flash memory sourced from Tier 1 contract manufacturers and undergoes five stages of testing: wafer sorting, surface-mount technology (SMT), H5 ageing tests, full-capacity testing, and batch quality inspection. Genuine Tier 1 NAND has a bad block rate of less than 1 per cent (as an industry benchmark) and a data retention period exceeding 10 years under standard storage conditions. Full-capacity testing means that a 128 GB storage device must be verified to have a capacity of 128 GB, rather than simply being shipped based on the controller's label.


Bus-powered OTG across Android, Windows, macOS, Linux
OTG support runs on Android 4.0 and above via USB-C, plus HarmonyOS, Windows, macOS, Linux, smart TVs and in-car USB hosts. The drive is bus-powered, so no external supply, no battery and no driver install - plug it in and the volume mounts. Note for your product page: iOS devices require a separate adapter, which is not included in the box.


Customs logo Printing
The 128 otg pendrive comes with wide imprint area 57x35mm on both faces with customs logo printing via silscreen,laser engraving ,uv printing or full color printing. Fondatop also support MOQ 50PCS with free logo printing,and extra service of file preload Up to 2 GB of data preload is free, with autorun and data-lock available; client files are deleted permanently once the order closes.


Products Apperance
Zinc-Alloy Shell
The all-zinc alloy casing offers 1,000G impact resistance; its rotating mechanism is designed for 10,000 cycles, and its operating temperature range is −40°C to 85°C. A drive that can withstand the rigours of pockets, toolboxes and parcel boxes, effectively protecting the data it contains. Furthermore, the metal surface allows for clear laser engraving, give you a luxury appearance.So daily use in warehouses, vehicles, or field service kits won't crack the housing or loosen the hinge over years of handling.


Cap-Free 360° Swivel
One thumb movement exposes the connector; closing it provides full protection. This eliminates the two most common category failures: lost caps and fractured hinges. Fewer field failures mean fewer replacements and fewer complaints over the programme's lifetime.
