Nilight Motorcycle USB Charger with Voltmeter and Dual QC3.0 USB — Black, 7/8" Handlebar Mount, Waterproof, On/Off Switch

Nilight's motorcycle USB charger is a waterproof handlebar-mounted power adapter with a built-in voltmeter, independent on/off switch, inline 10A fuse and dual QC3.0 USB ports for fast charging phones and tablets.

This compact accessory turns your motorcycle, ATV, UTV, scooter or boat into a convenient charging station while showing real-time battery voltage. Designed for 7/8" (22 mm) handlebars but also mountable to flat surfaces, the unit offers two high-speed USB outputs, an LED voltmeter to monitor electrical health, and a protective cap to keep ports dry when not in use.

How fast and compatible are the USB ports?

The Nilight charger uses Qualcomm QC3.0 technology plus smart IC detection so both ports can deliver optimal charging to connected devices. It supports typical USB-powered gadgets including smartphones, tablets, GPS units, and action cameras without manual voltage selection.

• Dual USB outputs: 5V 3.4A combined / 9V 2.5A / 12V 2A per port when supported
• QC3.0, SCP and FCP compatible for faster recharge on supported devices
• Smart IC automatically adjusts current to protect battery and device
• Charges two devices at once at near-full speed

How does the voltmeter and switch help manage motorcycle battery health?

The built-in LED voltmeter displays the system voltage so you can spot low or abnormal readings before they become a problem. An independent on/off rocker switch prevents parasitic drain when you’re parked, and the LED also indicates whether the unit is active.

• Clear voltage readout for immediate battery status checks
• On/off switch isolates the charger to avoid battery drain
• LED indicates power state; voltmeter turns off with the switch
• Rubber protective cap keeps the display and ports sealed from water and dust

What mounting and installation options are available?

Installation is flexible: use the handlebar O-shaped clamp for 7/8" bars or the supplied pad bracket and screws for flat surfaces like dashboards and roll cages. Power connection can be made via SAE quick-connect or the included SAE-to-O-ring harness with an inline 10A fuse for a direct battery hookup.

• Mounts to 7/8" (22 mm) handlebar with O-ring bracket
• Pad bracket and screws allow non-handlebar mounting on many vehicles
• Two power methods: SAE quick-connect or SAE to O-ring harness with 10A fuse
• 42.5" cable length provides plenty of reach to the battery/connector

Is this unit durable and weatherproof enough for outdoor use?

The charger is built with a waterproof rubber cap and a sealed switch to resist rain and dust in normal riding conditions. While it's designed for outdoor vehicle use, ensure connectors are closed when exposed to heavy spray or extended submersion is likely.

• Waterproof rubber caps protect ports and switch from moisture
• Sealed switch and housing for everyday outdoor exposure
• Inline 10A fuse adds a safety layer at the power source
• Suitable for motorcycles, ATVs, UTVs, boats, RVs and more

Who is this for: Riders, off‑road enthusiasts and vehicle owners who need reliable, fast charging on the go and want to monitor their battery at a glance. It’s ideal for anyone mounting accessories to 7/8" handlebars or needing a compact, weather‑resistant USB power solution that can be turned off to preserve battery life when parked.
