Qjin Car Charger for NOCO Boost GB40, GB70, GBX45 Car Jump Starter & Cordless Car Vacuum, Tire Inflator - Dual Port, 12V Car Cigarette Lighter Fast Charging Adapter

I keep a few essentials in my glovebox: a tire inflator, a compact cordless vacuum, and a jump starter. The thread that ties them together is simple power access, and that’s where this Qjin car charger has become the small but reliable link in the chain. It’s a compact 12–24V adapter with both USB-C (PD up to 36W) and USB-A, and after several weeks of use in two vehicles, it’s earned a permanent spot in my center console.

Build and design

The first impression is the metal shell. It’s not just cosmetic; it gives the charger a reassuring heft, helps it shed heat, and makes it easier to seat firmly in a 12V socket. The texture adds a bit of grip when pulling it out of a tight port. Dimensions are tidy and low-profile, so it doesn’t stick out far or interfere with shifter movement or cupholders.

The fit in the socket is snug with no wiggle—important for cars with a looser accessory port or those that transmit more vibration. Across a bumpy gravel road and several hours of highway driving, I never had a dropout. There’s no bright, distracting lighting, and it blends into the dash like it belongs there.

One note: it doesn’t include any cables. That’s not unusual, but you’ll want the right ones on hand—USB-C to USB-C for newer devices and jump starters, USB-A to micro-USB or USB-A to USB-C for older gear.

Power and performance

The headline spec here is USB-C Power Delivery up to 36W. In practice, that’s enough to fast-charge phones, small tablets, action cameras, many handheld gaming devices, and newer compact jump starters that accept USB-C PD. It won’t power a big laptop, but it can trickle some ultralights if you’re in a pinch.

Using a USB power meter in a 12V car, I saw the USB-C port negotiate standard PD profiles and consistently deliver in the high-20s to low-30s watts depending on the device’s request. An iPhone on a USB-C to Lightning cable pulled typical PD rates (peaking near 20W), while a USB-C tablet hovered around the mid-20s. On the USB-A side, I measured a steady 5V at around 2.4A with a compatible load, which is appropriate for legacy accessories and older jump starters that charge via micro-USB.

With both ports active, the charger maintained stable output without disconnects. As you’d expect in a compact adapter, total power appears shared, so heavy, simultaneous loads will distribute the available headroom. Charging a phone at fast rates on USB-C while topping up a small accessory on USB-A worked smoothly; using two high-demand devices at once will slow one or both down a bit, but not to a crawl.

Real-world use

• Jump starter: My older unit charges via micro-USB, and the USB-A port provided the expected ~2A at 5V, bringing it from low to full over a couple of hours. A newer USB-C PD model negotiated a higher voltage and filled much faster. It’s exactly the kind of “top up while you drive” accessory you want for jump starters.
• Tire inflator: Some modern inflators have a rechargeable pack that tops up via USB. The USB-C port handled it without complaint. The charger kept up even while the inflator’s 12V plug was running in another vehicle—nice if you rotate gear between cars.
• Cordless car vacuum: Similarly uneventful, which is exactly what you want. I topped up between errands on the USB-A port.
• Phones and tablets: Both Android and iOS devices drew solid fast-charge rates. Over a weeklong road trip with navigation and music streaming, it kept my phone comfortably in the 90% range without getting hot.

Heat and stability

Cigarette-lighter adapters can run warm under sustained load. The metal housing on this one makes a noticeable difference: it spreads heat and keeps surface temperatures lower than many plastic housings I’ve used. Even after an hour of charging a tablet at PD rates, the shell was warm but not concerning. I didn’t encounter thermal throttling or intermittent cutouts, and there was no audible coil whine.

As always, a caveat: some older vehicles have finicky accessory sockets or weaker fuses. If you see repeated dropouts, check the socket tension and make sure you’re not sharing that circuit with something else high-draw.

Vehicle compatibility

It’s rated for 12–24V, which means it works in standard passenger cars and in 24V systems like some trucks and RVs. I tried it in a compact crossover and a half-ton pickup without any differences in behavior. The form factor didn’t obstruct flip-down covers or lids in either vehicle, and the retention spring kept it anchored.

Ergonomics and daily use

Little things matter. The ports are easy to access, and the body is short enough that it doesn’t snag. The metal finish resists scratches from keys and other console clutter. I do wish there were a subtle indicator light to confirm power at a glance, especially since some vehicles cut power to the socket when the ignition is off. It’s not a deal-breaker, but it’s a convenience feature I appreciate on other adapters.

Limitations and trade-offs

• No cable included: Plan on carrying at least a USB-C to USB-C and a USB-A to micro-USB or USB-C cable if you’re supporting a mix of old and new gear.
• 36W ceiling on USB-C PD: Great for phones, small tablets, and PD-enabled jump starters, but not enough for power-hungry laptops. If you routinely charge a laptop on the road, you’ll want a higher-wattage solution and a beefier 12V circuit.
• Shared output: With both ports loaded heavily, expect some power sharing. That’s typical at this size and price point but worth noting if you’re trying to fast-charge two demanding devices simultaneously.
• Metal can get toasty in a hot cabin: The heat dissipation is a net positive under load, but on a summer day in direct sun the shell gets warm before you plug in. Not unusual, just be aware.

Who it’s for

• Drivers who carry USB-C PD gear and want a reliable, compact charger for phones, small tablets, and accessories.
• Owners of USB-rechargeable jump starters, tire inflators, and cordless vacuums who prefer to keep everything topped up between stops.
• People with multiple cable types in the car; the combination of USB-C and USB-A simplifies mixed-device charging without dongles.

If you need to power a gaming laptop or run two high-draw USB-C devices at full speed, you’ll outgrow this. For most day-to-day automotive charging, though, it strikes a very good balance of size, build, and capability.

Tips for best results

• Use quality, short cables—especially for PD. A flimsy or overly long cable can limit charge speed.
• Know your socket: some are switched (off with the ignition), others are always-on. That affects overnight charging and battery drain.
• Seat it firmly; if your socket is loose, rotate slightly until the spring contacts bite. Avoid yanked side loads from heavy cables hanging off the ports.

The bottom line

This Qjin car charger gets the fundamentals right: stable PD performance up to 36W, a robust metal build, a compact footprint, and both USB-C and USB-A to support new and legacy gear. It handled everything I plugged into it—from a PD-capable jump starter to a tire inflator’s pack and multiple phones—without hiccups, rattles, or excessive heat. The lack of included cables and the 36W ceiling are the main trade-offs, but they’re reasonable given the size and purpose.

Recommendation: I recommend it. If your in-car charging needs center around phones, tablets, and USB-powered automotive accessories—and you value a sturdier build with consistent performance—this charger is an easy, confidence-inspiring choice for the glovebox.
