ETENWOLF Air 5 Portable Air Pump — Full Specifications

The ETENWOLF Air 5 is the flagship of the Air series — a large-capacity portable electric air pump with a 10,400 mAh / 38.48 Wh battery (4× the Air 2/3), a 720 L/min free-flow rate (2× the Air 2/3), and a 15 W PD USB-C charge input. On a single charge it inflates approximately 115 standard sleeping pads (60 × 190 cm, 22 s each) or powers a 10 W USB-A power bank output for approximately 2 phone charges. Maximum output pressure is 4.5 kPa (0.65 PSI) — like all Air-series pumps it is a low-pressure, high-volume inflator and is not suitable for car tires, SUP boards, or sports balls.

Core Performance Specifications

The Air 5 moves 720 L/min at zero back-pressure — twice the Air 2/3 — enabling a 60 × 190 cm sleeping pad inflation in just 14 seconds (vs ~22 s for the Air 2/3). Its 10,400 mAh Tianpeng-cell battery stores 38.48 Wh and charges fully in approximately 4 hours via 15 W PD USB-C; the USB-A output (10 W) doubles as a power bank for about 2 smartphone charges (5,000 mAh phone).

Air 5 vs Air 2/3 — Head-to-Head

The Air 5 outperforms the Air 2/3 in every measurable way except weight and charge time: 2× the flow rate, 4× the battery capacity, and roughly 2.4× the per-charge inflation count (115 vs 48 sleeping pads). The 310 g weight premium over the Air 3 is the trade-off for three nights of camping without recharging.

5 Included Nozzles

The Air 5 includes the same 5-nozzle kit as the Air 2 and Air 3, covering all common camping and recreational inflation scenarios.

Use Cases & Limitations

The Air 5’s 4.5 kPa maximum output makes it ideal for any large-volume, low-pressure inflatable — and its 10,400 mAh battery means it handles multi-day group camping without recharging. It cannot reach tire, SUP board, or sports ball pressures.

Operating Limits

The Air 5 runs continuously until its 70 °C thermal protection activates; the 10,400 mAh battery provides extended operation across multiple camp nights. It is not waterproof. Charge time of ~4 hours means overnight charging before a trip is the recommended workflow.

Frequently Asked Questions

How does the Air 5 compare to the Air 2/3 — is it worth the upgrade?

The Air 5 offers 2× the flow rate (720 vs 360 L/min), 4× the battery (10,400 vs 2,600 mAh), and roughly 2.4× the per-charge inflations (115 vs 48 sleeping pads). It also adds a USB-A 10 W power bank output. The trade-off is 310 g extra weight and a longer 4-hour charge time vs ~1.5 hours for the Air 2/3. If you camp multiple nights or inflate large items, the Air 5 is worth the upgrade.

How long does the Air 5 take to inflate a Queen-size air mattress?

At 720 L/min free-flow rate, a 200 L Queen mattress would theoretically fill in under 17 seconds at zero back-pressure. Actual time is longer due to valve restriction; for reference, a 60 × 190 cm single sleeping pad (~30 L) inflates in about 14 seconds at the same conditions (25 °C, 100% battery).

Can the Air 5 inflate car tires or a SUP paddleboard?

No. Car tires require 200–350 kPa (29–51 PSI) and SUP boards require 70–100+ kPa. The Air 5 maxes out at 4.5 kPa (0.65 PSI). For tire inflation see the ETENWOLF S-series; for SUP inflation see the S4 SUP Pump.

How many sleeping pads can the Air 5 inflate on one charge?

Approximately 115 inflations of a 60 × 190 × 5 cm single sleeping pad per full charge (10,400 mAh, 25 °C, 100% starting battery). Each pad takes about 14 seconds. This compares to ~48 pads for the Air 2/3 on their 2,600 mAh battery.

Can the Air 5 charge my phone? How many times?

Yes. The Air 5 outputs 10 W via USB-A. A 10,400 mAh battery can charge a 5,000 mAh smartphone approximately 2 times (accounting for conversion losses). Note: charging the Air 5 itself while it is outputting power is not supported.

Is the Air 5 too heavy for backpacking?

At 455 g the Air 5 is suitable for car camping and backpacking trips where weight is not the primary concern. For ultralight backpacking, the Air 3 (145 g) is a better fit. The Air 5 is 310 g heavier than the Air 3 but inflates 2.4× more pads per charge and adds power bank functionality.

How long does the Air 5 take to charge?

Approximately 4 hours from 0% to 100% using a 15 W PD USB-C charger. Recommend charging overnight before a camping trip. Charging while inflating is not supported.
