Antigravity Batteries XP-1 Micro-Start (Gen 2) 12V Lithium Jump Starter — 400A, USB-C PD 30W Compact Power Bank

The Antigravity XP-1 Micro-Start (Gen 2) is a compact 12V lithium jump starter that delivers emergency starting power, portable device charging, and a built-in flashlight in a pocketable package.

If you need a small, dependable booster to revive a dead vehicle battery or keep your devices topped up on the road, the XP-1 provides a modern, space-efficient solution. The Gen 2 update adds 30W USB-C Power Delivery for faster charging, a clear digital display for quick battery checks, and improved convenience features while maintaining a form factor that fits in a glove box, backpack, or console. Despite its modest size, the XP-1 supplies 400A of continuous start current with a higher peak capability to handle many 12V automotive starts. It also doubles as a portable power bank with USB-C and USB-A outputs and includes intelligent jumper clamps for safe, easy use.

How much starting power does the XP-1 actually provide?

The XP-1 is engineered to deliver reliable cold starts for many 12V vehicles without the bulk of traditional jump packs. It supplies a sustained 400 amps for starting, with higher short-term peak output to overcome tougher cranking conditions. This makes it suitable for most gasoline engines and many diesel applications, depending on engine size and state of charge.

• 400A continuous starting current for routine 12V starts
• Higher peak output for brief surges during initial cranking
• Works with many cars, light trucks, motorcycles, ATVs, and smaller diesels
• Intelligent clamps protect against incorrect connections

How can XP-1 keep my devices powered away from an outlet?

Beyond jump-starting, the XP-1 functions as a compact power bank with multiple outputs. USB-C Power Delivery at up to 30W supports faster charging for phones, tablets, and some laptops; the USB-A Quick Charge port handles older devices. A 12V output is also available to run small accessories or top up automotive devices.

• USB-C PD 30W for quick charging and laptop compatibility
• USB-A Quick Charge port for legacy devices
• 12V DC output for accessories like pumps or inflators
• Pass-through use: charge the unit and power devices simultaneously

What safety and convenience features help during roadside use?

The XP-1 includes several design elements that make emergency use more confident and efficient. A built-in digital display gives immediate insight into remaining capacity and active ports, while the included LED flashlight offers multiple modes to illuminate a dark scene. The jumper clamps have built-in protection to reduce the risk of reverse polarity or short circuits, and the battery chemistry offers more stable power-to-weight than traditional lead-acid packs.

• Clear digital readout for battery level and port status
• Integrated LED flashlight with steady and strobe modes
• Intelligent clamp electronics to help prevent mistakes
• Lightweight lithium design for easy storage and handling

How long does the XP-1 hold a charge and how do I recharge it?

Battery retention depends on storage conditions and usage, but the XP-1 uses lithium cells designed for low self-discharge compared with older battery types. Recharging the unit is fast and simple using the USB-C input; the 30W PD input shortens top-up time compared with micro USB or lower-watt chargers. For long-term readiness, store the unit charged and top it up periodically according to user manual recommendations.

• Low self-discharge lithium cells for prolonged standby readiness
• USB-C PD input allows faster recharging of the unit itself
• Charge and use at the same time for convenience
• Carry case and compact size simplify storage between uses

Who is this product best for? The Antigravity XP-1 Micro-Start (Gen 2) fits drivers and outdoor enthusiasts who want a lightweight, easily stowed fallback for dead batteries and a versatile power source for electronics. It's ideal for commuters, road-trippers, motorcyclists, and anyone who values a small emergency kit over a heavy jump pack. If you need a balance of reliable starting performance, fast device charging, and compact portability, the XP-1 is designed to give peace of mind without taking up much space.
