FlyAuto 6 in 1 Jump Starter with Air Compressor 260 PSI Tire Inflator,Upgraded 1800A Peak 12V Portable Car Battery Jump Starter,400 Watt Inverter Power Station with AC/DC/USB Outlets

Why I keep this FlyAuto jump starter in my trunk

Emergency gear tends to either be overhyped or underused. This one’s different. After several months with the FlyAuto 6‑in‑1 jump starter riding shotgun in my trunk, it’s become the kind of tool I reach for far more often than “only in emergencies.” It’s a jump pack, a tire inflator, a small inverter power station, a flashlight, and a general-purpose 12V/USB power source in one box. There are lighter and sleeker lithium packs on the market, but this lead‑acid unit trades a bit of bulk for staying power and versatility that’s hard to beat at the price.

Setup and first impressions

Out of the box, I plugged it in and let it charge for a full day, per the instructions. Don’t skip this step—it matters for peak output and battery health. The housing is sturdy enough for trunk life, the carrying handle is solid, and the controls are straightforward. The AC inverter, DC sockets, USB port, compressor, and light are clearly labeled. There’s no fancy app or touch screen here, just simple switches and indicators that are easy to read.

One immediate observation: this isn’t a featherweight. The lead‑acid 20Ah battery gives it more reserve than most pocket lithium boosters, but it does make the unit heavier. I’m fine with the trade-off since I value runtime and repeat-use capacity.

Jump‑starting performance

This is where the FlyAuto earns its keep. The 12V booster is rated at 1800 peak amps (500 instant), and in practice it had no trouble starting a mid-size gas sedan with a dead battery on a cold morning. I also used it on a larger gasoline SUV that had been sitting for weeks—clamps on, key turn, and it fired up on the first try. The clamps are adequately sized with a strong spring, and the spark-proof, reverse-polarity protection did its job: when I tested a reversed connection, the unit simply refused to energize until I fixed the leads.

A few tips from use:
- Give it that full first charge (24 hours) and top it off monthly if it lives in your vehicle.
- If the battery is deeply discharged, let the unit “wake” the battery for 30–60 seconds before cranking.
- Avoid multiple long cranks back-to-back; let the unit rest between attempts to keep internal heat in check.

Compared to compact lithium packs, it’s not as pocketable, but it feels more forgiving on repeated starts and seems to hold a standby charge well if you maintain it properly.

Tire inflation: handy, with realistic expectations

The integrated compressor is the feature I’m most grateful to have along. It’s quick for topping off passenger tires a few PSI and excellent for bikes, lawn equipment, and small powersports tires. For a standard car tire that’s dropped into the mid‑20s, it took a few minutes to get back into the early 30s. On larger SUV tires, expect a slower go—still workable, just not fast.

The digital gauge on the unit tracked closely with my handheld gauge, within a couple PSI. The included nozzles cover sports balls and other inflatables, and switching attachments is straightforward.

A few practical notes:
- Let the compressor cool after extended runs. Small onboard compressors like this benefit from duty cycles (for example, 10 minutes on, 10 off) to prevent overheating.
- For frequent, large tire inflation (trucks, off‑road deflations), a dedicated higher‑capacity compressor will be faster.
- If you’re picky about target pressures, cross‑check with a known-accurate handheld gauge.

Power station chops: 400W inverter and useful ports

The 400W inverter is what elevates this from “emergency tool” to “everyday utility.” With two 110V AC outlets, I’ve run a laptop charger, a router during a brief outage, and charged power tool batteries on site. It’s also fine for small fans, LED lights, and similar loads. As always with inverters, check your device’s wattage and leave headroom; this unit isn’t for kettles, hair dryers, space heaters, or anything that spikes well above 400W.

Beyond AC, you get:
- Two 12V DC sockets for coolers or other car‑style accessories.
- A 5V/2.1A USB port for phones and tablets.

The USB is serviceable but basic—no fast‑charge protocols beyond 2.1A. If you rely on modern fast charging, carry your own PD power bank. Still, as a backup, it’s reliable and steady.

Runtime and practicality feel like the strong suit. Because it’s a 20Ah lead‑acid, the unit delivers a predictable, usable chunk of energy for AC/DC tasks without the drop-off you sometimes see in tiny lithium packs. Just remember: the more you use the inverter, the less reserve you’ll have left for jump-starting until you recharge.

LED work light and field usability

The built‑in LED work light isn’t a floodlight, but it’s bright enough to illuminate a tire change or engine bay at night. The beam is wide, and the switch is glove-friendly. I appreciate that the light and compressor can run without complicated mode switching—you just flip what you need.

One small gripe: there’s no great spot to stash the AC charging cable and inflator nozzles. I ended up tucking them into a small zip bag that rides with the unit. Built‑in storage or a pouch would make the package tidier.

Safety, maintenance, and longevity

FlyAuto’s spark‑proof and reverse‑polarity protections are confidence‑boosters, especially if you’re loaning the unit to someone less familiar with jump packs. Indicator lights make it clear when you’re connected correctly.

Because this is a sealed lead‑acid battery, plan for basic maintenance:
- Store it fully charged and top it up monthly, especially in cold weather.
- Avoid leaving it discharged; sulfation reduces capacity.
- Don’t bake it in extreme heat for long stretches. If you park outdoors in hot climates, bring it inside when practical.

Treat it well, and you’ll get more consistent output from both the booster and inverter.

Where it shines—and where it doesn’t

What I like:
- Reliable starting power with forgiving behavior on repeated uses.
- Genuinely useful compressor for topping off and small inflatables.
- A 400W inverter with two AC outlets is rare at this price and adds real utility.
- Clear, simple controls and a rugged carry handle.
- Built‑in light that’s actually helpful.

What I’d change:
- Weight and size are noticeably more than lithium jump packs.
- The compressor is slow on larger tires; adequate, not speedy.
- Only one USB port and no fast‑charge standards.
- No integrated storage for accessories or the wall charger.

Who it’s for

• Drivers who want an all‑in‑one roadside kit: battery boost, air, light, and power for small devices in one unit.
• DIYers and homeowners who like having a portable 120V/12V power source for quick tasks without dragging out extension cords.
• Campers and tailgaters who need modest AC power and reliable 12V/USB charging.

Who should look elsewhere:
- Ultralight travelers who prioritize compact size over versatility.
- Users who regularly air up large truck tires or run high‑draw AC appliances—get a dedicated high‑output compressor or a larger inverter power station.

The bottom line

The FlyAuto jump starter earns a permanent spot in my trunk because it does the two things I need most—start cars and manage tires—while doubling as a capable little power station. It’s not the fastest inflator nor the most compact jump pack, and the USB options are dated, but the combination of a stout booster, usable compressor, 400W inverter, and straightforward safety features makes it a practical, confidence‑inspiring tool.

Recommendation: I recommend it. If you want a dependable, do‑most‑things emergency unit with real AC power on board, this is an easy pick. You’ll trade some weight for that capability, and power users might still want dedicated tools for specific tasks, but as a single box to solve common roadside and around‑the‑house problems, it’s a smart, well‑rounded companion.
