Best mini jump starter packs 2019

Don’t get caught out with a dodgy battery as we test eight of the best jump starter packs

An ailing battery can cause you grief, but a lithium jump pack can soon sort starting problems. Small enough to pop in a glovebox, they can get you on your way without the need for jump leads.

A larger battery size (usually measured in Ah) means generally easier starting and more reserve charging power for phones etc., but adds weight and cost. Some buyers just want emergency starting capability; others demand the versatility of extra sockets and laptop adaptors. Our tests focus on starting ability as we rate the cheaper gadget chargers on sale.

How we tested them 

For our starting test, each device had to assist an ailing battery on a 1.6-litre petrol engine, turning it over five times for five seconds, with two minutes in between attempts.

We logged battery state at the end and rated each starter for practical features such as cable length and clamp size, tech spec and weight. Instructions were also rated, as were safety and options, including sockets. As ever, price from a range of online sources was the final factor.

Verdict

  1. 1. MSC Overland Waterproof Car Jumper & Power Bank
  2. 2. Clarke JSM300 Micro Jump Start and Power Pack
  3. 3. MSC Overland Plus Power Bank & Jump Starter

Review

MSC Overland Waterproof Car Jumper & Power Bank

Price: around £65Rating: 5/5

Despite being the lightest product here, at 481g, MSC’s multiple test winner achieved five perfect engine starts, with 100 per cent charge indicated at the finish. Water-resistant to the IP54 standard, it could be charged via mains, car or USB (with solar charging optional), and featured two USB sockets rated at 3A combined. The leads, recently lengthened to 36cm, are on par with most others, and the 8.7Ah gives it enough to start a car with plenty in reserve for charging gadgets. Its price and covered sockets provide sufficient edge to push the Clarke into second place.

 

Clarke JSM300 Micro Jump Start and Power Pack

Price: around £78Rating: 4.5/5Contact: www.machinemart.co.uk

The JSM300 is Clarke’s mid-range Jump Start device, offering a neat balance of capability and price. Rated at a healthy 12Ah, it matched the MSC Best Buy’s starting and battery state results. The two USB sockets combined to offer 4A but, as with the power outlets, they were uncovered. Outputs of 5V, 12V and 19V were easily selected, the latter being for laptops, and eight adaptors for them were included. We liked the zip-up case that kept everything together with elasticated straps and included mains and car chargers. It was very close to picking up a win.

 

MSC Overland Plus Power Bank & Jump Starter

Price: around £110Rating: 4/5

With a whopping 18Ah on tap, the Plus version of MSC’s winner barely flinched at our starting tests, finishing with the battery state still at 100 per cent. Presented in a hard, zipped case, it’s dust/waterproof to the IP65 standard and comes with chargers for mains, USB and car. In addition, it has eight adaptors for charging a laptop; one worked well on our HP. It seems mean to have just one USB, but it has a multi-way cable to make life easier. Massively capable, if heavy, at 919g, this device can do almost everything.

 

Draper Expert Lithium Jump Starter 150667

Price: around £108Rating: 4/5

Lots of things to like about this powerful 12Ah Draper, starting with the strong hard case, complete with USB and car charging connections. As with the MSC Plus, it features eight useful laptop adaptors, together with a four-in-one multipurpose charging lead which covers various permutations of Apple and USB fitments. It easily completed our tests, although the battery state lost an LED and a few points. We liked the long, 42cm leads and the option to charge at 12V, 16V or 19V, although an extra USB socket would be good. A great product and nearly a podium.

 

Energizer Lithium-Polymer Car Jump Starter 50805

Price: around £74Rating: 3.5/5

Despite its lowly claimed 7.2Ah, this Energizer managed all our tests, albeit with less enthusiasm than some and with only three of four battery-state LEDs lit at the end. It’s the only charger not to feature a torch and doesn’t have a protective case or bag, either – both unusual in the current market. Charging is via USB only, with no direct mains option, although it does include a car charger. We liked the leads, the longest measuring 44cm. But while the jump start socket is covered, none of the others is, including the single 2.4A USB.

 

Laser 7405 Jump Starter Multi-Function

Price: around £121Rating: 3.5/5

The new offering from Laser did well on our starting tests, completing all five and keeping the four LEDs glowing at the end, despite its low Ah. It includes some unique touches, such as a clear, red LCD screen which obviously shows the state of play for starting. It has two USB sockets, one of which is QuickCharge 3.0, and in addition, it features a USB C socket for input or output – all cutting-edge stuff. Charging is via a micro USB, although mains and car chargers aren’t included. An impressive unit, light at 559g, but too new for us to get a keener price.

 

NOCO GB40 Genius Boost Plus 1000A Jump Starter

Price: around £87Rating: 3.5/5  

This features top build quality and a tough, no-nonsense casing – a good job, with only a fibre bag for protection. It’s the smaller of the two NOCOs we tried and we liked the clear layout with large buttons for the light and on/off, and a simple LED set-up that made getting it wrong impossible. The heavy-duty croc clips connected via a large plug/socket and it turned the engine nicely. However, it had lost one of its LEDs at the end, is heavy, at 905g, features only one USB socket and isn’t cheap.

 

NOCO GB50 Boost XL 1500A Jump Starter

Price: around £126Rating: 3/5 

As the name and price suggest, this is a step up from the GB40, in terms of power and size, but still with no hard case and just one covered USB socket. The design and quality remain the same, but at 1.1kg, it was the heaviest and priciest unit here. As with the smaller version, the instructions are good and it’s designed to start batteries down to 2V.  Again, the twin, seven-mode LEDs shone usefully at the croc clips, towards the connections. The engine was turned over quickly and for all five tests, leaving three of four LEDs lit.
