WOLFBOX 4000A Jump Starter Power Pack, 12V Car Battery Booster Jump Starter with 65W Quick Charger, 88.8Wh Battery Booster Pack (10L Gas 10L Diesel Engine) with LED Light, Booster, Jump Leads

I bought this item not expecting much from it as I have a Porsche and not started for months, bearing in mine this has a very high compression six cylinder engine and the original battery is Hugh so after fully charging the unit off I went. Turned the key and just a click from the engine as expected. Fitted the booster as instructed and believe me the instructions are very simple and the unit automatically switched on and saying to start vehicle, well that engine started in a nano second, to say i was amazed is an under statement. I am completely in love with this booster and to top it all off it is saying that i still have 93% charge left so in theory i can start the car another 9 times without recharging unit. This is a fantastic piece of kit. Just make sure you buy the correct amps for your car, 4000 Amp booster will start anything so overkill for most family vehicles, get the 2000 Amp unit in that case as it is cheaper. I highly recommend this booster and I don't recommend much to be honest. I checked the unit to see if it holds charge after 2 weeks and it has retained its charge rate, brilliant. It is a very compact and versatile unit as you can also charge your phones or laptop with it and stores in a very hard protective case. Best buy for me in years.

Well packaged good quality at a good price Got this to. Assist starting my old campervan, which it easily does . Comes with a nice storage bag

This box could not have been better, we have a large 4x4 truck which it started easily and so easy to use thanks wolfbox

Looks like a great bit of kit. Not used in anger yet. Good size digital read out and easy to use/read. Clamps are quite resistant but that means better gripping force. Arrived at 75% charge. Put it on charge and 100% was achieved within 30mins. Quite quick really. Supplied with storage case which is sturdy. Makes storing it in your car a breeze.

Excellent product, does the job. Used to start a tractor and a landrover

Easy to use, I've, done 6 flat battery starts no problem with power. However the leads are woefully short which makes it very difficult to use.

Excellent product and quality works well

Amazing bit of kit. I don't normally do reviews but this is probably best thing ive bought in long time. Ive got quite a large motor that has a lot of electrics on it. If I don't use it often the battery will fail to start the car. Ive used this a few times now. If the battery is really flat it gives a little alarm when using wolfbox so just use the boost. Worth every penny this.

Awesome jump starter. Easy to use, compact and just works. Useful to aid batteries in the frigid temperatures start ups. Used on Tractor after sitting in below freezing temps, robust on start. Only used 2% of stored energy. Nice readout. Only downside is the short cable. Not a deal breaker.

Great, until now. Didn't have the chance to try yet. Small size, powerful, and charges fast

Lo usé para una camioneta Tow & country con su batería totalmente descargada y prendió de inmediato. Lo recomiendo ampliamente

Ik wil niet opscheppen ofzo, maar ik ben in bezit van een porsche boxter uit 1997. Deze auto's trekken gemiddeld een accu sneller leeg dan een andere auto. Nu was ik ook nog vergeten de FM adapter uit het dashboard te trekken, dus na 4 dagen: Alleen een klik bij het starten. Startkabels zijn geen optie in mijn carport, ivm met ruimtegebrek, dus maar een kijken naar een alternatief. Ik kwam de Wolfpack 4000 A tegen alhier en besloot de gok te wagen na het kijken van youtube recensies.... Ik ontving hem net, pakte hem uit, kabel erin en naar de auto...... Aangesloten, starten en : VROEM! Echt in 1 keer starten! Accu capaciteit was 75% bij aankomst en na starten, 74%. Dus als dit ding een 6 cilinder kan starten zonder problemen, kan ik hem alleen maar aanraden!
