4-in-1 roadside essential

Never get stranded again. PowerBoost X4™

A 4000A portable jump starter, 150 PSI air compressor, 24,000mAh power bank and emergency LED light — four tools in one compact device that fits in your trunk and works in any condition.


PowerBoost X4 4-in-1 jump starter air compressor power bank emergency light

Dead battery. Flat tire. No signal. The road doesn't care.


Being stranded is more than an inconvenience — it's a safety risk. Whether it's a dead battery on a cold morning, a flat tire on the highway, or a phone running out of battery in the middle of nowhere, the PowerBoost X4™ handles all of it from a single device you already have with you.

4000A peak current — jump-starts cars, SUVs and trucks
150 PSI compressor — inflates a car tire in 60 seconds
24,000mAh power bank — charges phones, tablets and GPS
Emergency LED — flashlight, SOS and strobe modes
Sound familiar?

The moments every driver dreads


Dead battery with no one around to help

Waiting for roadside assistance can take hours. With a 4000A portable jump starter in your trunk, you're back on the road in minutes — no other car needed.

Flat tire with no pump and no petrol station nearby

A slow puncture or low tyre pressure leaves you vulnerable. A 150 PSI portable air compressor inflates a standard car tyre in under 60 seconds — no pump needed.

Phone dead when you need it most

No map. No emergency call. No way to contact anyone. A 24,000mAh built-in power bank keeps your devices charged through any situation.

Why it wins

Four tools. One device. Always ready.

Every feature built so you're never caught unprepared on the road.


1

4000A peak jump starter

2000A starting current and 4000A peak current jump-starts dead batteries on cars, SUVs, trucks, motorcycles and more. Smart clamps protect against reverse polarity, short circuit and overheating.

2

150 PSI air compressor with auto shut-off

Set your target pressure and walk away. The smart compressor automatically stops inflating the moment the set PSI is reached — no overinflation, no guesswork.

3

24,000mAh portable power bank

USB-C fast charging keeps the unit topped up in 3–4 hours. USB-A and USB-C output ports charge phones, tablets, GPS units and other USB devices on the go.

4

Emergency LED — 3 modes

High-brightness flashlight for roadside work, SOS flash to signal for help, and strobe mode for visibility in traffic. Never be invisible in an emergency.

5

All-season performance

Operates reliably from -25°C to 85°C. Whether it's a winter morning freeze or summer heat on a long road trip, the PowerBoost X4™ performs when you need it.

6

Compact enough for your trunk

At 21 × 9 × 6.5cm and packed in a heavy-duty carry case, the PowerBoost X4™ fits easily in a glove box, boot, or bag — always there, never in the way.

FAQ

Questions answered.


Yes. The PowerBoost X4™ delivers 2000A starting current and 4000A peak current, which is sufficient to jump-start most cars, SUVs, trucks and motorcycles with 12V battery systems. Connect the smart jumper clamps, wait for the green ready signal, and start the engine.
A standard car tyre inflates in approximately 60 seconds. Motorcycles take around 45 seconds and bicycle tyres around 30 seconds. Set your target PSI using the digital display and the compressor automatically stops when the pressure is reached — no manual monitoring required.
Using the included USB-C cable, the unit fully recharges in approximately 3–4 hours. You can also charge it via any standard USB-A adapter. We recommend keeping it charged and stored in your boot so it's always ready when you need it.
Yes. The PowerBoost X4™ is engineered to operate reliably from -25°C to 85°C, making it fully functional in winter conditions when dead batteries are most common. The lithium polymer cell maintains its charge capacity better in cold temperatures than standard lead-acid batteries.
The smart jumper clamps detect reverse polarity immediately and will not allow current to flow until the connection is corrected. An alert will notify you of the incorrect connection before any damage can occur to your vehicle's electrical system or the PowerBoost X4™ itself.
Absolutely. The 24,000mAh power bank outputs via USB-C and USB-A ports, charging smartphones, tablets, GPS units, cameras and laptops. At 24,000mAh it will fully charge most smartphones 6–8 times from a single charge of the unit itself.
