YESPER 12V Portable Car Jump Starter 1500A — Compact Motorcycle & Car Booster with USB Power Bank and Safety Protections

YESPER 12V Portable Car Jump Starter is a pocket-sized 1500A jump pack that delivers reliable boost starts for cars, motorcycles, trucks and more while doubling as a USB power bank.

Designed to balance size, power and safety, this mini jump starter packs high cranking ability into a notably smaller and lighter housing than many competitors. It’s built to revive drained 12V batteries, supply emergency starting power even from a fully depleted battery, and offer convenient USB charging for phones and small electronics — all with multiple built-in protections to reduce risk during use.

How much starting power does this jumper provide?

The unit is rated at 1500 amps peak cranking current, giving it enough surge to start a wide range of 12V vehicles including cars, motorcycles, ATVs, vans, SUVs and many light trucks. The high-amp output is intended for short-duration boost starts rather than continuous cranking.

• 1500A peak current for quick engine starts.
• Capable with most 12V lead-acid and AGM batteries (not for SAE-connector systems).
• Designed for single-boost cycles to restart engines, not prolonged operation.

What safety features protect me and my vehicle?

YESPER integrates a multi-layer protection suite to minimize hazards during jump-starting, such as spark prevention and reverse-polarity guarding. These safety functions help prevent short circuits, incorrect hook-ups and other common risks when handling battery clamps and power packs.

• Spark-proof connection to reduce ignition-related risks.
• Reverse polarity detection and automatic cutoff.
• Additional protections: over-current, over-voltage and short-circuit prevention.

Can this unit charge phones and other devices?

Yes — the jump starter includes a 5V/2.1A USB output for fast charging of phones, tablets and many USB-powered gadgets, making it a practical emergency power bank. The USB port provides top-up power when vehicle power is unavailable.

• Single USB output rated 5V/2.1A for phones and tablets.
• Useful for emergency charging while stranded or outdoors.
• Small form factor fits glove boxes, bags or console compartments.

What makes this model different from other jump starters?

This YESPER model emphasizes portability without sacrificing cranking ability: it’s significantly thinner, smaller and lighter than many similar jump boxes. It also offers a one-button BOOST function to aggressively start vehicles from very low or completely drained batteries.

• Compact footprint — noticeably thinner and lighter than typical models.
• BOOST button for forced starts when battery voltage is extremely low.
• Built for convenience: easy storage and straightforward operation.

Who is this for? If you want a lightweight, travel-friendly emergency starter that still delivers strong cranking power, the YESPER 12V 1500A portable jump starter fits commuters, motorcyclists, outdoor enthusiasts, small-fleet owners and anyone who values compact roadside assistance gear. It’s suited to drivers who need a dependable, easy-to-stow booster with basic USB charging and robust protective electronics — ideal for those who prefer a no-fuss solution for occasional jump-starts rather than heavy-duty, professional-grade battery systems.
