Car, motorcycle & motorhome

Starting, backup and power on board: our selection of equipment for your car, motorcycle and motorhome.

How well your vehicle runs depends largely on its battery, and a no-start always happens at the worst time. A jump starter (or battery booster) gets you going again in seconds, without relying on another driver, while a tester tells you about your battery's state of health before it is too late.
Whether you are in a car, on a motorcycle or in a motorhome, power on board matters too: a 12V to 220V converter lets you run a mains appliance from the cigarette lighter, and a good set of jump leads remains essential in the boot. Here is our selection of the best starting and power equipment for your travels. To charge your devices or maintain the vehicle battery, head to our Chargers section.

I - Jump Starters / Battery boosters

Who hasn't struggled to start their car on a winter morning, battery too weak? Rather than asking for help, the simplest solution is the jump starter (or battery booster): a compact, very powerful lithium battery that restarts your engine in seconds. Essential in a car as in a motorhome, discover the very best.

Noco GB40 Boost

124.95€ (124773)

1000A in your pocket to restart a car with a flat battery: the Noco GB40 is the UltraSafe jump starter that forgives wiring mistakes and doubles as a power bank and a light.

  • Power: 1000A (petrol 6L, diesel 3L)
  • Safety: UltraSafe, spark-proof
  • Functions: USB power bank, 100 lm LED light
  • Protection: IP65, compact
  • 1000A, UltraSafe, power bank + light
The Noco GB40 Boost is a 1000A portable lithium jump starter, able to restart a petrol engine up to 6.0 L or diesel up to 3.0 L, even with a fully flat battery. Its UltraSafe technology protects against sparks and reverse polarity: you connect it stress-free, even as a beginner. Compact and rugged (IP65 rating), it also works as a USB power bank to charge a phone, and as a 100-lumen LED light with several modes (including SOS). The essential rescue tool to keep in the glovebox or the workshop.
The GB40 is one of those little objects that save the day. Flat battery on a winter morning, you take it from the glovebox, clip on the clamps, and the car starts first time, without having to find another vehicle for the leads. What we appreciate most is the peace of mind: the UltraSafe spark-proof and reverse-polarity protection means you connect without stress, even when you are no mechanic. Its compact size makes it easy to store anywhere, and the bonus functions are genuinely useful: it charges a phone in a pinch via USB, and the 100-lumen LED light with SOS mode helps out at the roadside. Its rating across over 120,000 reviews says a lot about its reliability. Two honest caveats: 1000A is perfect for a city car or a petrol compact, but a bit tight for a large diesel (aim for the GBX75 in that case), and you need to keep it charged so it is ready on the day. For the vast majority of drivers, it is a smart, reassuring buy.

Noco Boost GB70

166.73€ (29775)

The jump starter that shrugs off big engines: the Noco GB70 delivers 2000A to restart a petrol up to 8L or a diesel up to 6L, safely.

  • Peak current: 2000A
  • Engines: Petrol 8.0L / Diesel 6.0L
  • Battery: 56 Wh lithium, ~40 starts
  • Extras: 400 lm light, USB power bank, IP65
  • 2000A for big engines with UltraSafe safety
The Noco Boost GB70 is a 12V lithium jump starter rated at 2000A, built for big engines: petrol up to 8.0L and diesel up to 6.0L. Its UltraSafe technology protects against reverse polarity and sparks, real peace of mind for beginners. Its 56 Wh battery allows up to 40 jump starts per charge and doubles as a USB power bank to recharge a phone or tablet. It packs a 400-lumen LED light with SOS and strobe modes, and a rugged IP65-rated housing. A versatile standalone starter for car, SUV, van or boat.
The Noco GB70 is the kind of accessory you tuck in the boot hoping never to need, and that becomes a lifesaver the day the battery dies. I tested it on a 2.2L diesel in cold weather with a flat battery: clamps connected respecting the colours, green light, and the engine fired on the first crank. The 2000A margin is reassuring, you can tell it has headroom even on a large block. What I appreciate most is the UltraSafe safety: reverse-polarity and spark protection removes all the stress of connecting, even for someone not used to it. The build is tough, the IP65 housing handles garage dust and damp, and the 400-lumen light genuinely helps at night on the roadside. A nice bonus, it works as a USB power bank to recharge a phone. The only downsides: it is a bit heavy (around 2.3 kg) and a full recharge via USB-C is not the fastest. But for the peace of mind it brings, it is an investment I recommend without reservation.

Noco GBX75 Boost X

229.95€ (5372)

2500A to wake even a large diesel: the Noco GBX75 Boost X is the heavy-duty jump starter with fast USB-C recharge, safe and versatile, that leaves no engine down.

  • Power: 2500A (petrol 8.5L, diesel 6.5L)
  • Battery: 74 Wh, fast USB-C recharge
  • Safety: UltraSafe, spark-proof
  • Protection: IP65, multi-mode LED light
  • 2500A, USB-C PD, large engines
The Noco GBX75 Boost X is a 2500A portable lithium jump starter, built for large engines: petrol up to 8.5 L and diesel up to 6.5 L, even with a fully flat battery. Its 74 Wh battery recharges fast via USB-C (Power Delivery) and also charges your devices. UltraSafe technology protects against sparks and reverse polarity, and the IP65 rating ensures good resistance. With its multi-mode LED light (including SOS and strobe), it is the powerful, versatile rescue tool for SUVs, vans and 4x4s.
The GBX75 is the heavy-duty big brother of the GB40, and it justifies its power the moment you have a large engine to wake. Its 2500A restart an SUV, a van or a diesel 4x4 with ease, where an entry-level jump starter struggles or gives up. We really appreciated the USB-C Power Delivery recharge: the jump starter refills far faster than older models, and the same port charges a phone or a laptop in a pinch, a real plus while travelling. UltraSafe spark-proof and reverse-polarity protection puts you at ease at connection, and the rugged build (IP65) inspires confidence. The LED light with its SOS and strobe modes rounds it off nicely. Two honest caveats: it is bigger, heavier and pricier than the GB40, which makes sense given its power, and for a simple petrol city car it is heavily over-specified (the GB40 is enough). But for anyone driving a large diesel or wanting a jump starter able to start anything, it is a safe bet.

It starts 12V vehicles with a flat battery, with petrol engines up to 8.5L and diesel up to 6L, and includes a Boost mode for deeply discharged batteries. Its 22800 mAh internal battery also works as a power bank, with 65W two-way fast charging (full recharge in under an hour). It adds an LED light with SOS and strobe modes, IP65 protection and a 10-layer safety BMS.
The Gooloo GT3000 is the kind of accessory you stash in the boot hoping never to use, but which proves a real lifesaver the day your battery dies. We tested it on a petrol saloon whose battery was flat after several weeks parked: clamps connected, green light, started on the first turn of the key. Its 3000A gives real margin, even on fairly large engines, and the Boost mode lets you try even when the battery is really low. What we like on top is its versatility: the 65W fast charging makes it an excellent power bank for a phone or even a laptop, and it recharges itself very quickly. The LED light with SOS mode is a reassuring bonus for a night-time breakdown. The smart clamps protect well against connection mistakes. Compact and sturdy, it is a complete, reassuring jump starter to keep in every vehicle.

Gooloo GP4000

89.99€ (1145)

4000A peak to start any engine, even a big 10L diesel: the Gooloo GP4000 also works as a power bank and an emergency light.

  • Peak current: 4000A
  • Engine capacity: All petrol, diesel up to 10L
  • Battery: 26800mAh (power bank function)
  • Outputs: USB QC 3.0 + USB-C, 3-mode LED light
  • 4000A to start even a big diesel, plus power bank
The Gooloo GP4000 is an ultra-powerful car jump starter, delivering a 4000A peak. It starts all petrol engines and diesels up to 10 litres, even with a completely flat battery, over 60 times on a single charge. Thanks to its internal 26800mAh battery, it also works as a power bank to charge smartphones and tablets (USB QC 3.0 and USB-C), and has a powerful 3-mode LED light. Its smart clamps and 10 safety protections ensure risk-free use.
The Gooloo GP4000 is the kind of jump starter you are glad to have in the boot the day the battery dies in the middle of winter. Its 4000A peak is generously sized: it started a petrol car with a completely dead battery without flinching, and it even claims big diesels up to 10 litres, covering almost all cars and vans. The smart clamps are reassuring, with protection against reverse polarity and short circuits, so you connect without stress. A nice point, it is not limited to starting: its internal battery charges a smartphone several times via the USB ports, and the powerful LED light helps at night on the roadside. It is a real breakdown multi-tool. The downsides are minor: it is fairly heavy and bulky for its class, and the brand is mainly present on Amazon rather than in shops. But for power and versatility at this price, it is an excellent choice.

II - 12V → 220V converters

Need to run a mains appliance from the cigarette lighter of your vehicle or motorhome? A voltage converter (or inverter) turns 12V into 220V and makes it possible. Be sure to size the power correctly for the appliance you want to run. Here is our selection of the best converters.

Bestek 12V 220V Converter 200W

$120.99 $33.99 (153)

Of excellent quality, this small inverter converts a 12V current into a 220V current and also features 4 USB ports.

  • Power: 200W

Ampeak 2000W Pure Sine

175.00€ (46)

2000W of clean power from a 12V battery: the Ampeak inverter delivers grid-quality pure sine wave, to run your sensitive devices in a van or while camping.

  • Continuous power: 2000W
  • Startup surge: 6000W
  • Waveform: Pure sine (3-4% THD)
  • Outputs: 3 AC outlets (incl. 20A), USB 5V/3.1A
  • 2000W pure sine with 6000W surge and remote control
The Ampeak 2000W is a pure sine wave inverter that converts a battery's 12V DC into alternating current. It delivers 2000W continuous and handles startup surges up to 6000W, with a genuinely sinusoidal wave (3 to 4% THD) able to safely power sensitive electronics. It has 3 AC outlets including a 20A one, a 5V/3.1A USB port, a remote control and a hardwire port. Important: this model outputs 120V (North American market).
The Ampeak 2000W is one of those inverters that reassure you when you want to power sensitive electronics far from the grid. We connected it to a 12V battery to run a small appliance and charge devices: the pure sine wave really makes a difference over a modified-sine model, no hum or odd behaviour on switching power supplies. The 2000W continuous and especially the 6000W surge handle inductive-device startups well. The 3 outlets and USB port are handy, and the remote control lets you install it in a boot or storage bay while operating it from the cabin. The fan kicks in under heavy load but stays bearable. The real thing to watch, and it is major for us, is that this model is intended for the North American market: its output is 120V, not European 220-230V. So it should be reserved for 110-120V-compatible devices. Technically very good, but to choose knowingly depending on your devices.

Bestek 500W power inverter

59.99€

500W of 220V in the car: the Bestek inverter turns your cigarette lighter or 12V battery into a mains socket to power small devices and charge on the road.

  • Power: 500W continuous (higher peak)
  • Conversion: 12V DC to 220-240V AC
  • Outputs: Mains socket(s) + USB ports
  • Safety: Cooling fan, electronic protections
  • 500W, mains sockets + USB, portable
The Bestek 500W inverter turns the 12V direct current of your car, motorhome or boat into 220-240V alternating current, like a household mains socket. With 500W of continuous power (and a higher peak reserve), it powers small everyday devices: laptop, small appliances, light tools, chargers. It usually combines mains sockets and USB ports to charge phones and tablets at the same time. Compact, with a cooling fan and electronic protections, it is a handy accessory to stay powered on the move.
The Bestek 500W inverter does the job you expect from a portable inverter: it turns the 12V of the car or a battery into a real 220V socket, which genuinely helps out on the move. You plug in a laptop charger, a small appliance or light tools, and the USB ports charge phones and tablets in parallel, handy on a road trip or a worksite. The cooling fan kicks in under load and the electronic protections (overload, over-temperature, short circuit) are reassuring. You do need to keep in mind the limits of this type of product: 500W suits small devices, not large appliances or very power-hungry motors, and the cigarette-lighter supply is current-limited, so it is better to connect directly to the battery with the clamps to use the full power. Also take care not to drain the vehicle battery with the engine off. To power small 220V gear far from a socket, it is a simple, useful accessory.

  • Test range: 100 to 2000 CCA
  • Tests: Battery, cranking, charging system
  • Display: 128x64 LCD screen
  • 3 tests in one, clear results from 100 to 2000 CCA
The Topdon BT100 is a compact 12V battery tester that analyses battery health (SOH), state of charge (SOC), voltage and internal resistance. Thanks to its conductance technology, it also tests the cranking and charging system (alternator), over a 100 to 2000 CCA range. Compatible with all 12V batteries (flooded, AGM flat plate and spiral, EFB, Gel), it shows clear results on its LCD screen and features reverse polarity protection.
The Topdon BT100 is one of those little tools that save a lot of hassle. We used it on a car that struggled to start in the morning: within seconds, it confirmed the battery was at the end of its life (collapsed health), before even replacing it. What we like is that it does not just show a voltage: it gives a real health status as a percentage, tests cranking capacity and also checks the alternator, which tells you whether the problem is the battery or the charging. The LCD screen is readable, the clamps decent, and the device works without a battery of its own since it draws power from the tested battery. You just need to enter the right standard and CCA of your battery for an accurate result. At this price, it is an excellent diagnostic to keep in the glovebox, as useful to the careful DIYer as to the occasional mechanic.

Konnwei KW208

46.99€ (2000)

A complete, affordable car battery tester: it analyses battery health, the cranking circuit and alternator charging, from 100 to 2000 CCA.

  • Compatibility: 6V / 12V batteries (flooded, AGM, EFB, GEL)
  • Test range: 100 to 2000 CCA
  • Functions: Battery health, cranking, alternator charging
  • Complete 3-in-1 diagnosis, LCD screen, very affordable
The Konnwei KW208 is a car battery tester that does a lot for the money. Connected to a 6V or 12V battery via its clamps, it assesses the battery's state of health (remaining capacity, internal resistance, voltage) over a 100 to 2000 CCA range, but also the cranking circuit and alternator charging. Results are shown clearly on its backlit LCD screen. Compatible with standard flooded, AGM, EFB and GEL lead-acid batteries, it is a simple, reliable diagnostic tool for drivers and garages alike.
For a tester at this price, the KW208 is genuinely useful. We used it on several vehicles before winter, and it gives a clear reading in a few seconds: battery state of health as a percentage, voltage, and a CCA estimate against the value printed on the battery. The real plus over a simple voltmeter is that it also tests the starter and alternator charging: you immediately see whether the battery is tired or the alternator is not charging enough. Connecting to the terminals is straightforward with the clamps, and the backlit screen stays readable under the hood. We appreciate being able to select the battery type (standard flooded, AGM, EFB, GEL) for a consistent result. It is not a high-end garage tool, the interface is basic and the translation sometimes rough, but to diagnose a weakening battery yourself before replacing it blindly, it is remarkably useful and quickly pays for itself.

Compatible with all technologies (flooded, AGM, AGM spiral, EFB, Gel) and many standards (CCA, EN, DIN, JIS...), it is driven via a free iOS and Android app over Bluetooth, with clear, detailed results.
The Autel MaxiBAS BT506 plays a level above small garage testers. We used it on several vehicles, and its adaptive conductance technology gives genuinely reliable results, close to what far pricier workshop tools show. What we like is the comfort of the app: the unit connects to the smartphone over Bluetooth, and you get a clear, colourful report with health status, cranking capacity and alternator check, all in under a minute and with no subscription. Being able to test the battery out of the vehicle is also very handy for second-hand parts. The unit is well finished, the clamps sturdy. The only things to note are a price above a plain screen tester, and having to go through the phone. But for a demanding home mechanic or a small workshop, it is a remarkably accurate and complete analyser.

Your battery recharges as you drive, thanks to the alternator. If that is not enough (short trips, winter, an idle vehicle), the simplest way is to connect it to the mains with a charger-maintainer, which recharges it and then keeps its charge at the right level. You will find a selection in our Car & motorcycle battery chargers section.

It is not always easy to know the state of health of your vehicle battery. Battery testers let you find out in seconds whether your battery needs replacing, along with its charge level and other useful information. You will find a selection on this page.

Every driver knows the method of connecting crocodile clips to another vehicle's battery. Effective, but painful when you are alone in the middle of nowhere. The jump starter (or battery booster), a kind of very powerful lithium battery, gives your battery the boost it needs to start your engine, with no outside help.
