Record range 3.2 m – the longest set on the market
Socket under the desk. Laptop on the table. The cable barely reaches. Know that feeling? Most power adapters have a meter, at most one and a half – forcing you to work in one position, in one place, without the possibility of movement. The Hardy® 65W power adapter has a cable length of 3.2 meters — long enough to comfortably reach sockets behind furniture, under café tables, or in a distant corner of a conference room. You no longer need to rearrange furniture or search for an extension cord. You sit where you feel comfortable and just work. You stop adapting your life to infrastructure – infrastructure adapts to you.
Precise Dell 4.5×3.0 mm connector – secure fit for Inspiron, Vostro, and Latitude
Classic business Dell laptops require an advanced power source identification system. The Hardy® adapter delivers a full 65W power exactly where ordinary USB-C chargers physically cannot connect. Simply attach the sturdy DC 7.4×5.0 mm tip included in the set to the cable. Equipped with a central signal pin, it allows Latitude, Inspiron, and Vostro series computers to identify power adapter parameters. This minimizes the risk of incompatibility messages, supports stable battery charging, and maintains full processor performance under load.
USB-C – one power adapter for the entire ecosystem
This is the revolution and true universality of this set: this power adapter is a chameleon that adapts to your needs. When you’re not using the laptop, simply detach the DC tip for the main cable to turn into a pure, universal USB-C connector with Power Delivery technology. The same adapter will support your classic computer and moments later safely and quickly charge a modern smartphone, tablet, headphones, or next-generation laptops. No more carrying a bunch of separate chargers and desk chaos – HARDY® replaces them all.
Energy transformation always generates heat, which is the number one enemy of electronics longevity — capacitors, diodes, and transistors lose efficiency faster when working at elevated temperatures. Inside the Hardy® power adapter housing, a CoolPad™ thermally conductive silicone pad is used, actively absorbing heat where it is generated most and evenly dissipating it across the entire housing surface. The effect is noticeable even during long hours of operation — the adapter remains distinctly cooler, components are not exposed to localized overheating, and retain full performance for much longer.
Armoured durability and safety
The Hardy® power adapter is built to protect expensive equipment at every level. The fireproof V0 material housing according to the strict UL94 standard prevents flame spread. Oxygen-free copper (OFC) provides better conductivity and corrosion resistance, while the ferrite core eliminates electromagnetic interference. Electronic protection circuits — OVP (overvoltage), OCP (overcurrent), SCP (short circuit), and OTP (overtemperature) — monitor parameters in real time and react immediately, safeguarding the computer from damage.
65W stable power – energy tailored to your devices
65 watts is the ideal balance point in the world of modern power supplies. It provides enough power to support most laptops, ultrabooks, and tablets – even under full load. After detaching the DC tip and switching to native USB-C charging, the HARDY® Laptop Power Adapter™ activates the USB Power Delivery protocol. This standard automatically negotiates optimal parameters with each connected device – laptops and ultrabooks receive up to 65W, tablets up to 30W, and smartphones as much as they currently need. Everything happens automatically without your intervention, ensuring reliable power in any situation and guaranteeing full battery safety for mobile devices.
