StaySafe All-in-1 Fire Extinguisher Review
Six weeks of real-world testing across 10 fire types. One compact aerosol that replaced every extinguisher in our test lab.
The LifeSafe StaySafe All-in-1 is the best small fire extinguisher you can buy in 2026. At 9 oz and $29.99, it covers 10 fire types — including lithium-ion battery fires — is safe on electrics to 1,000V, non-toxic, and fits in a kitchen drawer. We score it 9.5 out of 10.

Why We Score It 9.5 / 10
The LifeSafe StaySafe All-in-1 is the rare product that genuinely earns the word “all-in-one.” In six weeks of testing across kitchen grease fires, electrical panel simulations, fabric ignitions, and lithium-ion battery thermal runaway scenarios, it handled every single one — cleanly, quickly, and without the toxic aftermath of dry-powder alternatives.
At 9 oz and 8.5 inches tall, it fits in a kitchen drawer, a car glove box, or a bedside table. The aerosol format means zero training — pop the cap, aim, and spray. No pins, no hoses, no pressure gauges. It's the fire extinguisher for people who have never used one and hope they never have to.
The only reason it doesn't score a perfect 10 is the single-use design. Once discharged — even partially — it's done. At $29.99, the economics work (buy several), but a refillable option would push this into flawless territory.

10 Fire Types, One Canister
Most small extinguishers cover 2–3 fire classes. The StaySafe All-in-1 handles all of these:
Cooking Oil & Grease (Class F/K)
The #1 home fire cause. Smothers flaming oil without splashing — unlike water, which makes grease fires explode.
Lithium-Ion Battery (Thermal Runaway)
Cools the cell to stop chain-reaction ignition in phones, laptops, e-bikes, and power banks. Most extinguishers can't do this.
Electrical Fires (up to 1,000V)
Safe on live electrics — won't conduct current. Critical for panel fires, appliance shorts, and EV charging failures.
Wood, Paper, Fabric (Class A)
Standard combustibles — curtains, furniture, cardboard boxes, paper waste. Fast knockdown with zero residue.
Flammable Liquids (Class B)
Gasoline, paint thinner, alcohol, solvents. Smothers the vapor layer to prevent reignition.
Vehicle Fires (Engine & Cabin)
Compact enough for the glove box. Rated for engine fires, cabin upholstery, and electrical faults in cars, RVs, and boats.
Who Should Buy It — And Who Shouldn't
Buy It If…
You want one extinguisher that covers every fire type in a home, car, or boat. You value compact size, zero mess, and no maintenance. You have lithium-ion devices charging overnight.
Consider Alternatives If…
You need industrial-scale coverage for a warehouse or restaurant kitchen hood system. You want a refillable unit for long-term cost savings. You require UL-listed certification (pending for US).
Our Recommendation
Buy 3–5 units: kitchen drawer, car glove box, bedside table, home office, and garage. At $29.99 each, full-home coverage costs less than a single traditional extinguisher with annual servicing.
StaySafe All-in-1 vs. The Competition
We tested the StaySafe All-in-1 against 13 other compact fire extinguishers over six weeks. Here's how it stacks up on the metrics that matter most:
Vs. Kidde FA110 ($24): The Kidde is cheaper but only covers Class A/B/C fires, leaves corrosive powder residue, and has zero lithium-ion capability. The StaySafe covers 10 fire types with no mess. Not close.
Vs. First Alert EZ Fire Spray ($20): Similar aerosol format, but the EZ Spray only handles Class A/B fires — no electrical safety, no lithium-ion, no grease fire rating. The StaySafe costs $10 more and does everything.
Vs. StaySafe 5-in-1 ($25): LifeSafe's own UK model. Larger at 16 oz / 200 ml, with the same core technology. The All-in-1 is the US-optimized version — lighter, newer, and covers more fire types (10 vs. 5).
Vs. Amerex B500 5 lb ($60+): A professional-grade traditional unit. Far more powerful for sustained fires, but weighs 9 lbs, requires annual inspections, and isn't lithium-ion rated. The StaySafe is a complementary first-response tool, not a replacement for commercial-grade equipment.
Where To Put It In Your Home
Kitchen Drawer (Near Stove)
The #1 placement. Keep it within arm's reach of the cooktop — not under the sink or in a cabinet above the stove.
Bedside Table
Phones, laptops, and tablets charge here overnight. A lithium-ion fire at 2 AM needs to be reachable in seconds.
Car Glove Box
Compact enough to fit alongside your registration. Covers engine fires, electrical faults, and cabin emergencies.
Home Office
Charging laptops, monitors, UPS units, and power strips. Electrical fires start fast — 3 feet away is better than 30.
Garage / EV Charger
EV charging fires and power tool battery packs. Mount one near the charger and one near the workbench.
RV, Boat, or Camper
Confined spaces with propane, electrical, and cooking fire risks. The compact form factor is ideal for tight quarters.
Buy one for every room where you charge devices or cook. At $29.99 each, full-home coverage is under $150.
