1. NOCO Boost Plus GB40: Best Overall
The NOCO Boost Plus GB40 is a top contender in the 800 amp jump starter category, offering a peak rating of 1000A. In our evaluation, it consistently started 6-liter gasoline engines and smaller diesels based on owner reports. Its safety features are industry-leading, including spark-proof technology and reverse polarity protection, which we verified against published safety standards. The compact design and integrated USB charging make it a versatile companion for roadside emergencies.
However, for owners of large diesel trucks or heavy equipment, the GB40 may fall short. Some users noted it struggled with 8-liter diesel engines in cold weather. If you drive a standard passenger vehicle or SUV, this is an excellent choice. But for heavy-duty applications, consider a higher peak current model.
- Rated 1000A peak, evaluated to start 6L gas and 3L diesel engines reliably
- Built-in spark-proof technology and reverse polarity protection for safe use
- Compact and lightweight design with integrated LED flashlight and USB charging
Pros: Trusted brand with consistent owner satisfaction; Excellent safety features including spark-proof and reverse polarity protection
Cons: Lower peak current than some competitors may not suit larger diesel engines
2. Clore Automotive Jump-N-Carry JNC660: Best for Large Engines
The Clore Automotive Jump-N-Carry JNC660 is a professional-grade jump starter with a 1700A peak rating, far exceeding the 800 amp class. In our evaluation, it easily started 8-liter diesel engines and large V8s based on owner feedback. The AGM battery is durable and replaceable, and the heavy-duty clamps provide a secure connection. This unit is built for frequent use in a shop or fleet setting.
However, its 18-pound weight and large size make it impractical for personal vehicles or storage in a glove box. It lacks USB ports and modern safety features like reverse polarity protection. If you need a portable emergency starter for daily driving, this is not the best fit. It is ideal for mechanics or those with large diesel trucks who prioritize raw power over portability.
- 1700A peak and 22Ah battery delivers strong starting power for large V8 and diesel engines
- Heavy-duty AGM battery with clamps designed for repeated use and long service life
- Includes a built-in voltmeter and work light for diagnostic convenience
Pros: Exceptional starting power for large engines; Robust build quality with replaceable battery and clamps
Cons: Heavy and bulky, not portable for everyday carry; No USB ports or modern smart features
3. GOOLOO GP2000: Best Value
The GOOLOO GP2000 offers an impressive 2000A peak rating at a competitive price point, making it a strong value pick. In our research, many users reported successful starts on large SUVs and trucks. Its compact size and USB-C charging are convenient for modern lifestyles. The included smart cables provide basic safety protections.
However, some owners noted that the battery capacity declined after a year of use, and the safety certifications are less transparent than those from established brands. If you want a budget-friendly option for occasional use on standard vehicles, the GP2000 is solid. But for frequent or heavy-duty use, consider a more durable model.
- 2000A peak rating, capable of starting 8L gas and 6L diesel engines
- Ultra-compact and lightweight design with USB-C input and output
- Includes smart jumper cables with spark-proof and reverse polarity protection
Pros: High peak current in a very compact package; Great value for the price with USB-C charging
Cons: Reported inconsistent battery life over time; Safety certifications not as clearly documented as premium brands
4. DBPOWER 800A: Compact Performer
The DBPOWER 800A is a compact jump starter that delivers adequate power for typical passenger cars. In our evaluation, it reliably started 4-cylinder and smaller 6-cylinder engines based on owner feedback. Its small size and integrated flashlight make it easy to store in a glove box. The dual USB ports are handy for charging devices.
However, its 800A peak rating is at the lower end of the category, and it may struggle with larger engines or in cold weather. Some users reported that the case felt flimsy. If you drive a compact or mid-size car and want a minimalist emergency tool, this could work. But for larger vehicles or heavy use, look for a higher-rated model.
- 800A peak rating suitable for most 4-6 cylinder engines
- Pocket-sized design with built-in LED flashlight and SOS mode
- Dual USB outputs for charging phones and tablets
Pros: Extremely portable and lightweight; Simple operation with clear instructions
Cons: Not powerful enough for larger V8 or diesel engines; Build quality feels less robust than premium competitors
5. TACKLIFE T8: Feature Rich
The TACKLIFE T8 packs additional features like a compass and thermometer, which set it apart from basic jump starters. In our research, it performed adequately for 4-cylinder and some 6-cylinder engines. The smart cable with LED indicators helps prevent incorrect connections, which is a nice safety touch.
However, the extra features may be gimmicky for many users, and the peak current is limited. Some owners found the compass and thermometer inaccurate. If you want a jump starter with extra gadgets for camping or hiking, the T8 is worth considering. But for pure starting performance, other models offer better reliability.
- 800A peak rating with smart cable and LED indicator for correct connection
- Built-in compass, thermometer, and multiple light modes
- Includes a carrying case and USB output for devices
Pros: Extra features like compass and thermometer may be useful for outdoor enthusiasts; Clear LED status indicators reduce user error
Cons: Peak current may not be sufficient for larger engines; Some owners reported the compass and thermometer are not very accurate
6. AUDIWELL 800A: Budget Pick
The AUDIWELL 800A is an entry-level jump starter that offers the essential functions at a low price. In our evaluation, it managed to start 4-cylinder engines in most cases, but performance was inconsistent. The included flashlight and USB charging are standard. It is a budget option for those who need a backup emergency starter.
However, durability is a concern. Several owner reviews mentioned the unit stopped working after a few months. Safety protections are minimal compared to competitors. If you are on a tight budget and only need occasional use for a small car, the AUDIWELL may suffice. But we recommend spending a bit more for a more reliable product.
- 800A peak rating for small to mid-size engines
- LED flashlight with strobe and SOS modes
- USB output for charging electronic devices
Pros: Lowest price point among the models we evaluated; Lightweight and easy to store
Cons: Inconsistent quality control and shorter lifespan reported by some owners; Safety features are basic and not as robust as premium brands
7. BEATIT 800A: Ultra Compact
The BEATIT 800A is designed for maximum portability, weighing under a pound and fitting in a pocket. In our research, it worked for small engines like motorcycles and lawnmowers, but struggled with larger cars. The USB-C input is a modern touch, and the LED light is functional.
However, its small battery limits its starting capability. Many owners reported failures on 4-cylinder sedans in cold temperatures. Safety features are basic. If you only need a jump starter for a small vehicle or as a last-resort emergency tool, the BEATIT may be acceptable. But for most drivers, a more powerful unit is advisable.
- Smallest and lightest in our lineup, fits in a pocket
- 800A peak for small engines, includes USB-C input
- LED light with emergency flashing modes
Pros: Extremely portable, ideal for motorcycles and compact cars; USB-C input for convenient charging
Cons: Lowest peak current and smallest battery capacity; Reported to have difficulty starting even some 4-cylinder engines in cold weather
Frequently Asked Questions
What does 800 amp mean on a jump starter?
800 amp refers to the peak current the jump starter can deliver in a short burst to start an engine. It is a marketing number, and real-world performance depends on the battery capacity and internal resistance. For most 4-6 cylinder gasoline engines, 800A is sufficient, but larger engines may require more.
Can an 800 amp jump starter start a diesel engine?
It depends on the diesel engine size. Small diesel engines (up to 3L) may start with an 800A unit, but larger diesels (5L and above) typically require higher peak current (1000A+). Check your engine’s displacement and cold cranking amps (CCA) requirements.
How do I maintain my jump starter battery?
To prolong battery life, recharge the jump starter every 3-6 months if not used. Avoid fully draining the battery. Store it in a cool, dry place. Most lithium units have built-in protection, but regular charging helps maintain capacity.
Is it safe to use a jump starter in the rain?
Most jump starters are not waterproof. Using them in heavy rain or standing water poses a risk of short circuit or electric shock. If you must use one in wet conditions, keep the unit dry and ensure connections are secure. Some models have weather-resistant cases, but always check the manual.
Can I use an 800 amp jump starter to charge my phone?
Yes, most 800 amp jump starters include USB ports for charging phones, tablets, and other devices. However, frequent use for device charging will drain the battery and may reduce its starting power. It is best to use it primarily as a jump starter.
