The ETENWOLF X5 Pro is a 2-in-1 portable jump starter and air compressor designed for compact cars. Delivering 800 A peak current and a built-in 22 L/min compressor rated to 160 PSI with precision auto-stop (±1 PSI), the X5 Pro handles both dead batteries and flat tyres from a single pocketable device. Available in a 6,000 mAh (22.2 Wh) standard version and an 8,000 mAh (29.6 Wh) MAX version, both configurations meet airline carry-on requirements. A USB-C PD 10 W power bank output adds a third function for device charging in the field.

Air Compressor Performance
The X5 Pro compressor delivers 22 L/min at up to 160 PSI. Precision auto-stop holds the preset pressure within ±1 PSI, eliminating the risk of over-inflation. The compressor and jump-start function share the same battery — ETENWOLF recommends starting the car first, then inflating, to ensure maximum energy is available for cranking.
| Inflation Scenario | Tyre Size | Start / End PSI | Time | Tyres per Charge |
|---|---|---|---|---|
| Full flat inflation | 205/55R16 | 0 → 35 PSI | ~4 min 30 s | 3 tyres |
| Top-up | 205/55R16 | 28 → 35 PSI | ~44 s | 16 tyres |
| Top-up | 215/55R16 | 28 → 35 PSI | ~55 s | 11 tyres |
All inflation figures are from factory test data. Actual times may vary with ambient temperature, tyre condition, and compressor temperature from consecutive use.

Frequently Asked Questions
What engine size can the X5 Pro start?
The X5 Pro is rated for gasoline engines up to approximately 1.5 L, making it well-suited for compact cars such as the Toyota Yaris, Honda Fit, Volkswagen Polo, and similar small-displacement vehicles. It is not rated for diesel engines. For larger engines — 2.0 L and above — consider the ETENWOLF X6 Pro (1,200 A, up to ~2.0 L) or the Helios J1 (2,000 A, up to 8.0 L gasoline / 6.5 L diesel).
How long does the X5 Pro take to inflate a car tyre?
From a complete flat (0 PSI) to 35 PSI on a 205/55R16 tyre, the X5 Pro takes approximately 4 minutes 30 seconds and can inflate 3 tyres per full charge. For routine top-ups from 28 to 35 PSI, the same tyre size takes about 44 seconds, and the unit can top up 16 tyres per charge. A slightly larger 215/55R16 tyre takes approximately 55 seconds for the same 28-to-35 PSI top-up, with 11 tyres per charge. All figures are from factory test data under controlled conditions.
Can I use the compressor and jump starter at the same time?
No. The compressor and jump-start function draw from the same battery, and simultaneous use is not supported. ETENWOLF recommends the following sequence: connect the clamps and start the vehicle first, then disconnect the clamps and use the compressor to inflate tyres. This order ensures maximum available current for cranking and avoids overloading the battery during the start attempt.
Can I take the X5 Pro on a plane?
Yes, both versions are well within airline carry-on limits. The 6,000 mAh version is rated at 22.2 Wh and the 8,000 mAh MAX version at 29.6 Wh — both are significantly below the 100 Wh threshold permitted by most airlines under IATA regulations. The unit must travel in carry-on baggage only, not in checked luggage. Always confirm with your airline before travel as individual carrier policies may vary.
What is the difference between the 6,000 mAh and 8,000 mAh versions?
Both versions deliver identical 800 A peak current and the same 22 L/min compressor performance. The differences are battery capacity and charge time: the standard 6,000 mAh (22.2 Wh) version charges in approximately 3.5 hours and can inflate 3 flat tyres per charge; the 8,000 mAh MAX (29.6 Wh) version charges in approximately 4.5 hours but provides greater reserve capacity for multiple inflation cycles or power bank use. The 8,000 mAh version weighs 870 g. Choose the MAX version if you frequently need to inflate multiple tyres or charge devices in the field.
