Kohree 12V USB Outlet 4-in-1 Panel, Upgraded 36W USB-C, Voltmeter & Individual Switch

The Kohree Upgraded 12V USB Outlet with individual switch is a compact 4‑in‑1 charging panel that provides two fast USB ports (including 36W USB‑C PD), a high‑power cigarette lighter socket, an LED voltmeter and a toggle switch for safe, convenient DC charging in vehicles and boats.

This multi‑port panel brings organized, protected power to cars, boats, RVs and ATVs. Built with over‑current, over‑heat and overcharge protection plus a visible voltmeter, it keeps devices charged while helping you monitor battery status. The panel’s individual switch lets you cut power to the USB ports to prevent drain when the vehicle is parked, and the rugged cigarette socket supports heavier accessories like vacuums and dashcams.

How fast and flexible are the USB charging ports?

The panel combines quick‑charge USB‑A ports and a Power Delivery USB‑C port for flexible, faster charging. Total USB output reaches 54W, with the USB‑C PD providing up to 36W and the QC3.0 USB‑A ports supplying high‑speed charging for phones and tablets.

• 36W USB‑C Power Delivery for fast charging compatible laptops, tablets and phones
• 18W QC3.0 USB‑A ports for rapid charging multiple devices
• Combined 54W output lets you charge two devices at high speed simultaneously

What protections and safety features does it include?

Kohree designed the unit with multiple automatic safety layers to protect your devices and vehicle electrical system. The panel shuts down or limits output if it detects overload, overheating or overcharging, and the bright voltmeter helps you spot abnormal battery voltage quickly.

• Integrated over‑current, over‑heat and overcharge protection
• Automatic shutdown when overload is detected to protect devices
• LED voltmeter for real‑time battery voltage monitoring and night visibility

Which accessories and vehicles is the cigarette lighter socket suitable for?

The built‑in cigarette lighter socket supports heavier DC loads, making it useful for common 12–24V accessories. It handles up to 150W on 12V systems and 300W on 24V systems, so it works with many car and marine add‑ons while fitting a wide range of vehicles.

• Works with dash cams, GPS units, portable vacuums and small inverters
• Rated 150W at 12V and 300W at 24V for higher‑draw devices
• Compatible with cars, trucks, boats, RVs, ATVs and camper vans (9–24V)

How does the individual switch and panel design improve everyday use?

The upgraded button switch lets you cut power to the USB outlet individually, reducing parasitic drain and extending vehicle battery life when parked. The compact 4‑in‑1 layout saves dash space while keeping ports accessible and easily replaceable if you want to swap sockets later.

• Button switch turns USB outlet off to prevent battery drain when not in use
• Compact, interchangeable 4‑in‑1 modular design for neat installations
• LED voltmeter and toggle switch provide clear status and control at a glance
