Product description

The ET05 is a portable 12V jump starter engineered to revive common vehicles with engines up to 7.2L gasoline and 5.5L diesel. Its peak output reaches 5000 amps, allowing prompt starts for cars, motorcycles, lawn mowers and other small-engine machines, even in harsh conditions from -4°F to 140°F.

Safety is a priority: the unit incorporates ten protection systems — including guardrails for overcharge, over-current, short-circuit, reverse-polarity, low- and high-temperature, over-voltage, over-load, spark suppression and reverse charge. Heavy-duty clamps and cables are provided; they feature indicator lights and audible alerts so you can confirm proper connection and detect errors before attempting a start.

With a 51.8Wh internal battery, the ET05 also functions as a portable power bank. It offers a 5V/2A USB output for charging phones and tablets, plus a Type‑C input supporting 5V/2A and 9V/2A for faster recharging. The housing includes a bright LED lamp with steady, strobe and SOS modes for roadside or outdoor emergencies.

The starter includes a high-power Boost mode that can help revive very weak batteries. If the vehicle battery drops below 2V, holding the BOOST button for 5 seconds will initialize the start assist; once the clamp LED turns green, the engine should be started within 90 seconds. A full charge can deliver up to about 20 jump starts depending on vehicle and conditions.

An LCD screen shows remaining charge and operating status at a glance. The unit measures roughly 6.3 in × 3.1 in × 1.6 in and weighs about 0.86 lb, compact enough for a glove box, emergency kit or backpack. Its shell is made from durable EVA material and the reinforced case offers water-, dust- and shock-resistant protection against everyday bumps and scrapes.

Package contents: 1 × SZEVZO ET05 Jump Starter, 1 × Smart Jump Cables with clamps, 1 × USB Type‑C charging cable, and 1 × User Manual. The product is backed by a two-year service warranty and customer support for troubleshooting or defects.

Does exactly what's needed

Revived a nearly dead car battery on the first try. No flashy extras, just reliable performance — a solid value for an emergency starter.

Arrived quickly and works well

Ordered internationally and it arrived on time. It functions as expected and has proven useful — glad I added it to my gear.
Bruce 5/5

Dependable and powerful

Started vehicles instantly and held charge well across repeated uses. We’ve used it several times and it remains reliable — highly recommended.
G. Bass 5/5

Feature-rich and fast charging

Bright display shows percent and voltage, and USB‑C recharges it quickly. Jumping my SUV used only a small fraction of the battery. Wish it came with a protective case, but otherwise excellent.
Danielle Marie 4/5

Handy size, well made

Looks great and is the right size for my emergency kit. Haven’t had to use it yet, but build quality feels very good.
PQ wong 5/5

Smart purchase for peace of mind

Perfect for someone who doesn’t drive daily. Setup indicators helped me connect it correctly and the whole process was straightforward. Worth keeping in a vehicle for unexpected battery trouble.

True roadside lifesaver

This compact jump starter has become indispensable. It fits easily in my glove box and has started my car multiple times without fail. The size doesn’t hinder performance, and the safety indicators make me feel comfortable using it.
