FNNEMGE Car Jump Starter 3500A Peak 26800mAh 12V Super Safe Jump Starter(Up to All Gas, 10.0L Diesel Engine), with 10W Wireless Charger Power Bank , USB Quick Charge 3.0

I am an engineer, just adding my inputs. I tested it with usb doctor, so at usb charging port from 100% to zero the battery registered at total power 40watts. The high power usb port on the battery did show intelligence where it turns it's voltage out from normal usb out of 5 volt to 9 volt and operated at 2 amps / total of 18watt charging capabilities. Neverthe less when operated to change devices total possible power output is 40watts ..However I opened it and check the battery in it and circuit, and I am happy to say that the battery is actually 14+ volts and is a stack with special arrangements and very heavily gaged wires for car starting, which is very good . Also since battery is a stack of multi batteries I can see a charging circuit which consist of battery management chip and property BMS , so not just 2 wire charging but using multiple dedicated wire to check and balance each battery in the stack.This means that this is a device primarily designed to produce very havery discharge currents and wired accordingly, which is exactly needed for car starting, and I can say that it will start your car when needed.That's why don't used it as primarily the usb charger for your devices, for that buy dedicated battery for charging phones and tabs.Keep this for the emergency as car starting and emergency charger for phone etc .Also don't use it for camping as , again this is designed and made for car jump starter... Can still be used to give out 12-14volts out for the devices like heavy lihghts etc .Again , please use it as car emergency starting device, for camping and others use the mobile charging battery sepratly and for camping there as special caping battery backup devices , use them please. Also such camping devices won't come in decent backup in less then 600 to 1000 aed as starting/ normal use .For caping consult some one before buying, because even o e use / needs are different and with different needs / devices , there are different requirements and not just one device can be used for it which is price optimism. You can easily end up spending decent amount and yet it may not serve the purpose/ backup time you needed. Therefore consult and invest on a backup caming device properly 🙂👍.I wrote this revive because for this price , the quality of this device is very good but you can't ask 300Aed device to do a job of 3000 aed power backup system 🤠 that would be a wrong expectations and that's why I see so many negative reviews of this device, which is due to unrealistic expectations... You do get what you paid for out of this device.Thanks and best wishesHave blessed day

This jump started my audi RS4 from a completely dead battery. Unbelievable given how small and light it is. I'd previously tried my old style battery pack which is massive and it couldn't even turn the starter motor over. This battery pack is small and light enough to keep in a glove box.

Bought the highest power available the 3,500A with peak at 26800mamp. Received item today , came with 82% charge, need to have or buy charger as per specs (not included) , once hooked up, it takes a while to start charging and see the percentage go higher, after that it start go faster in charging and the percentage goes higher more rapidly. Roughly 10% in one hour. Not bad. Comes with good quality bag , very handy. Comes with charging Cable which is C (power pack) to usb (charger) . Might need to buy C TO C cable as most chargers comes with C inlet.Jumped start the car immediately and lost only 1% of charge. That is impressive. Easy to use and quick start , car was 8 cylinder 4 liter.Will wait and see how long it will hold charge away from power. All in all this model works very well. I would give 5 star if it had charger included for the high price paid.

I tried it with dead battery in Ford Mustang 2006, it works perfectly

Bought as back up for the car, doesn't start the car, used once for charging my mobile, went dead flat in 1 hr.Complete wrongly description as it's only good as a power bank for mobiles.Also the light weight and size can be used for throwing if you got angry.

Didn't try to jump start the carBut tried to charge my phone took 50% to charge one phone

They charge gets lowered so quick i could barely jump a car one time and it is completely dead

It more equvalent to 5000 AH. It doesn’t last

Just purchased this product. Item weight as described 1 kg 100 gm, but it is wrong. The item weight is less than 500gm.

perfetto in ogni evenienza dalle auto ai camion , ho letto recensioni negative di chi non riesce ad avviare auto, lo starter non fà miracoli, la batteria completamente scarica potrebbe essere che la stessa sia a .. massa,, starter in questo caso è difficile che la avvii , se batteria è ancora in stato quasi ottimale starter va bene, io li usati su diversi modelli su diverse auto e fuoristrada sempre andato tutto ok, quando si collega alla batteria bisogna entro pochi secondi provare ad avviare auto altrimenti starter giustamente si spegne... e vorrei vedere, altrimenti se batteria auto è difettosa lo potrebbe danneggiare o scaricare completamente. lo starter non è fatto per ricaricare batteria auto ma solo per aiutare a mettere in moto.. quindi direi ottimo prodotto ma se si sà usare.... poi anche se non si usa pure che rimane nel cofano basta verificare stato carica ed eventualmente ricaricarlo 1 - 2 volte anno

En general el arrancador cumple bien con la función para la que se ofrece, únicamente he percibido un error que degrada la funcionalidad del aparato. Me explico: El enchufe del "smart clamp" al arrancador viene con la polaridad invertida, de modo que es impossible ver al mismo tiempo la pantalla LED y las luces roja y azul del "smart clamp".He visto en Internet toda clase de videos de arrancadores de diversas marcas, incluida esta, la FNNEMGE, y en ningún caso ocurre esta anomalía,por lo cual asumo que se trate más bien de un simple error humano en el taller de montaje de la fabrica que de un defecto de diseño.Por supuesto que me gustaría que Amazon subsanarse de alguna forma este error.

Partiamo dal presupposto che questo attrezzo serve per mettere in moto un autovettura e quindi il suo uso principale è solo questo. In questo campo si comporta egregiamente, la messa in moto è abbastanza agevole. Per quanto riguarda l'altra funzione, che consiste nel sfruttare le uscite USB per caricare i vari dispositivi elettronici, li mi trovo abbastanza in disappunto in quanto non riesci a fare due ricariche complete di un cellulare di nuova generazione. Pensavo a qualcosa molto più performante e quindi in fase di acquisto e meglio valutare la cosa. Spero che la mia recensione sia stata utile.

Solo funciono el primer arranque después de cargarlo al 100%,Como era de esperar "demasiado bonito para ser cierto"No me he molestado ni en ponerlo a cargar nuevamente ni en hacer más pruebas, claramente no está acorde a la descripción a pesar que me gusta y mucho tanto el producto como la carga inhalambrica y el estuchado, si no cumple con lo descrito y su objetivo que es arrancar al menos 2 o 3 veces el vehiculo, no me vale...Para cargar móviles y portátiles ideal, para arrancar coches no.
