Povasee A40 5000A Jump Starter — 12V Portable Power Pack, 3" LCD & 88.8Wh Power Bank

The Povasee A40 is a compact 5000A automotive jump starter that revives gasoline and up to 10L diesel engines, doubles as an 88.8Wh power bank, and includes a 3" LCD plus multi-mode LED for roadside safety.

Compact but rugged, the A40 is built to get stalled vehicles moving again and to keep your devices powered during emergencies. Its high-starting current, clear numeric display, and integrated protections make it a practical roadside companion for drivers, outdoor enthusiasts, and small-fleet operators. The kit includes heavy-duty smart cables, a USB-C charging cable, and a protective carrying case; a wall charger is sold separately.

How quickly will the A40 start my car or truck?

The Povasee A40 delivers a 5000A peak surge specifically designed to crank gasoline engines and diesel engines up to 10 liters in displacement, even when battery voltage drops under 9V. Start attempts are controlled and assisted by the RST button to provide the necessary burst on demand.

• 5000A peak starting current for immediate engine turnover.
• Works with cars, trucks, motorcycles, RVs, boats, lawn mowers, and more.
• Effective at low battery voltages below 9V when extra surge is needed.
• RST button for one-touch power surge during start attempts.

What information does the 3" LCD show and why does it matter?

The integrated 3-inch LCD gives you precise battery percentage, real-time voltage readings, and operation status so you can assess remaining capacity and see whether the unit is ready. This clarity helps avoid guesswork and reduces unsafe attempts to start when power is insufficient.

• Numeric battery percentage and voltage displayed clearly.
• Status icons for charging, discharging, and error conditions.
• Improves decision-making during roadside climbs and cold starts.
• Readable in low light for safer night-time troubleshooting.

Can the A40 charge phones and other electronics?

Yes — aside from jump-starting, the A40 is an 88.8Wh portable power bank with dual USB outputs, including a QC3.0-compatible port that provides faster charging. You can power two devices simultaneously and use the built-in LED modes for lighting or signaling.

• 88.8Wh capacity for multiple phone charges or small devices.
• Dual USB outputs, one supporting QC3.0 (5–12V) for rapid charging.
• Charge two devices at once while still ready to jump-start.
• Multi-mode LED (steady, strobe, SOS) for illumination and emergency signaling.

What safety and environmental limits should I expect?

Povasee built the A40 with 12 layers of electronic protection covering reverse polarity, over-current, short-circuit, over-charge, over-voltage and over-temperature, among others, to protect both the vehicle and the user. The unit is rated to operate across a wide temperature range for dependable performance in diverse climates.

• 12 advanced protections to prevent misuse and damage.
• Operates reliably from -4°F to 158°F (-20°C to 70°C).
• Smart jump cables reduce the risk of incorrect connections.
• Durable protective case included for transport and storage.

Who this is for: The Povasee A40 suits drivers who want a compact, high-power emergency starter that also functions as a fast-charging power bank. It's ideal for commuters, weekend adventurers, boaters, RV owners, small fleet drivers, and anyone who wants clearer battery status at the roadside. If you value a readable display, multi-device charging, and layered safety features in one portable pack, the A40 provides a practical, all-in-one solution for roadside power needs.
