Buyer’s Guide: 3 Key Factors to Consider
Power and Peak Amps
Don’t just look at the battery capacity (mAh); the peak amperage is crucial for starting your engine. For most standard petrol cars in the UK, a peak current of 1000-1500A is sufficient. If you have a larger diesel engine, aim for 2000A or more. Check your car’s manual to ensure the jump starter you choose meets its cold crank amps (CCA) requirements.
Build Quality and Safety
A lithium-ion battery pack is a powerful device, so safety features are non-negotiable. Look for protection against reverse polarity, short circuits, over-charging, and over-current. A robust, well-built casing can withstand the bumps and weather of being stored in your boot. A clear, easy-to-understand indicator light system is also vital so you know the unit’s charge level at a glance.
Portability and Extra Features
The main advantage of these devices is their portability. Consider the unit’s size and weight – it should be easy to store and carry. Many modern starters double as powerful power banks for your phone or other USB devices, and some even include a built-in torch, which can be a lifesaver during a nighttime breakdown. Decide which extras are truly useful for you.
Frequently Asked Questions
Q1: Can I use a portable jump starter on a completely dead battery?
A1: Absolutely. That’s their primary job. Unlike traditional jump leads that rely on a second vehicle’s live battery, a portable jump starter has its own independent power source, allowing it to jump-start a car with a fully flat battery on its own.
Q2: How long do these lithium-ion jump starters hold their charge?
A2: A good quality unit will hold a charge for several months, often between 6 to 12 months, when stored properly. It’s a good habit to top up the charge every 3-6 months, especially before a long journey or during colder weather when battery demands are higher.
Q3: Are they safe for someone with no mechanical experience?
A3: Yes, they are designed with safety and simplicity in mind. Most feature spark-proof technology and reverse polarity protection, which means if you accidentally connect the clamps incorrectly, the unit simply won’t operate, preventing damage to your car or the jump starter.
Q4: Can I take one of these on a plane?
A4: No, you cannot. Due to their high-capacity lithium-ion batteries, portable jump starters are prohibited in both checked luggage and carry-on bags by all major airlines. They are strictly for use in your vehicle.
Q5: What should I do if the jump starter doesn’t start my car?
A5: First, ensure the unit is adequately charged. Then, double-check that the clamps have a solid, clean connection to the car’s battery terminals. If it still fails, wait a few minutes and try again. If problems persist, the issue might be with your car’s starter motor or alternator, not just the battery.
Final Verdict: Which One Should You Buy?
After thorough testing, our top pick is the NOCO Boost Plus GB40 for its unbeatable combination of reliable power, compact size, and superior safety features, making it the best all-rounder for most UK drivers. If you’re seeking maximum power for larger vehicles, the STANLEY J5C09 is a robust choice, while the GOOLOO GP4000 offers incredible value and performance for those on a tighter budget, proving you don’t have to spend a fortune for peace of mind on the road.
