5.0 out of 5 stars Great Device to dilute those inconvenient low / flat battery scenarios where time creates anxiety.

Delivered the boosted start needed to my Merc 2014 E-Class (has start stop) perfectly after being stood for three weeks alarmed and onboard video surveillance took its toll. Also the convenience of getting to the battery with no chance of driving close enough for a traditional jump start, this device solved my problem job done. More features than expected as will recharge other devices via an outbound USB charge port. Delivering great functionality.Always follow the instructions and always check your vehicle manufacturers handbook, ref- jump starting as with all cars within the last 20-25 years, start-stop, other enhanced eco and ECU functionality can be disrupted or damaged if you are not aware and follow any due process suggested even for traditional jump starting.Very versatile, a single charge I believe will support multiple boosts (3 or 4) for car starting, probably true. For the money this is worth every penny, reasonably well built, and now travels with me as part of in-car on the road support to solve those rainy day issues that only happen when you time is of an essence.

5.0 out of 5 stars Simply a must have

Fantastic purchase. Charges quick, battery lasts very long. I've had one in the boot of my car for almost a year, used it 3 times for 2 cars and 1 small van, battery still showing high charge level. starts vehicles with ease. Nice and compact. Power output is more than sufficient and works perfectly.

5.0 out of 5 stars Excellent product

Superb bit of kit. Get a lot of use from single charge.

4.0 out of 5 stars Works well, Recharging instructions need to be clearer

A.C. · 1 January 2024

The unit arrived promptly within a day of ordering. It looked really light and i had serious doubts as to whether it would work. It came precharged to 4 arrows out of 5. I used it on my maserati quattroporte whose battery had gone flat. I tried plugging the cables onto the red jumpstart knob in the car's engine bay but it didnt work. so i opened the boot, found the car battery and plugged the cables directly onto the car battery and the car started straightaway. Did not have to use the boost function. the units charge dropped to 3 arrows after the single car jumpstart.There is no plug provided to recharge the unit . there are two cables though. I tried using my microusb phone charger overnight but it didnt charge. I was thinking of returning the unit, but then found one Bolo review mentioned that you need to used the usb charger. I didnt have a plug which would fit the usb charger. I found a laptop charger with a microusb tip and plugged that in. It charged from 3 arrows to 5 within a couple of hours.The instructions are too basic in my view and its difficult to read the letters in both the leaflet as well as on the unit. But the unit does the job and so im overall pleased with it and its good value.

5.0 out of 5 stars Great little booster

Does exactly what it says on the tin. Car wouldn’t start even after charging the battery. Put this on and the car started. Ideal to charge up and leave in the car for emergencies.

5.0 out of 5 stars Great power pack, sturdy cables, and lovely torch too

I've used this product to start up a couple of old cars with a dead battery and it worked like a charm. Very sturdy product, no issues whatsoever, and the built-in torch is also very strong and a great addition. Now I can go for long drives and also not worry about my car being parked up for a couple days with a potentially dead battery. Great kit for peace of mind, definitely must have if you're on the road quite a lot. Highly recommend!

5.0 out of 5 stars Works every time

This jump start product is great, it has never failed me, because I live in London, I don't have to use my car a lot, sometimes more than 3-4 months between journeys, by that time the battery is too low to start the car, the boost button. On this unit means my car starts every time, easy to use and very clear instructions, please note that I have tried another three jump start units on my car, and they all fail when the car battery is very flat, not this unit, highly recommended.

1.0 out of 5 stars Buy at a condition that battery life is less than a year.

Product was good so far since purchase last year in September and had use on multiple occasions. But recently it suddenly stopped like complete dead.. no functions working not charging. Tried the customer service email but provided wrong details. No one to contact.

Sie hat mir in einer echten Notlage geholfen: Meine Autobatterie war komplett leer und tiefentladen. Ich fahre einen Mercedes C180d (W205) und stand vor dem Problem, dass mein Auto einfach nicht mehr starten wollte. Normalerweise braucht man in so einer Situation ein zweites Fahrzeug und Starthilfekabel – aber das war bei mir nicht nötig.Mit der GREPRO Powerbank konnte ich mein Auto ganz alleine starten. Besonders beeindruckt hat mich die Boost-Funktion: Obwohl meine Batterie so tiefentladen war, dass eigentlich nichts mehr ging, hat ein Druck auf den Boost-Knopf gereicht und der Motor sprang sofort wieder an. Das hat mir enorm viel Zeit und Nerven gespart.Ich finde das Gerät auch deshalb so praktisch, weil es sehr einfach zu bedienen ist. Die Klemmen sind sicher, das Kabel zeigt mit LEDs an, ob alles richtig angeschlossen ist, und dank der vielen Schutzfunktionen hatte ich nie Angst, etwas falsch zu machen oder mein Auto zu beschädigen. Außerdem ist die Powerbank handlich, leicht und passt problemlos in den Kofferraum.Ein weiterer Pluspunkt: Ich kann mit der Powerbank auch mein Handy oder andere Geräte unterwegs aufladen und sie hat sogar eine eingebaute Taschenlampe. Das macht sie nicht nur für Notfälle, sondern auch beim Camping oder auf Reisen super praktisch.Für mich war die GREPRO 3000A eine echte Rettung und ich kann sie jedem empfehlen, der unabhängig und flexibel bleiben will – gerade wenn man mal alleine unterwegs ist und keine Hilfe zur Hand hat.

Good

Great item

Einwandfrei

S.S. · 13 June 2025

Hochwertige Verarbeitung, Bedienungsanleitung in verschiedenen Sprachen und viele Möglichkeiten. Von Handy laden bis Auto starten funktioniert alles einwandfrei. Man bekommt das ganze auch direkt in einer dazu passenden Tasche, damit es nicht alles frei rumliegt und besser transportiert werden kann.

Nice

This is a great tool. I haven't used it for the car yet since I just replaced the battery after the battery gave out and my friend came over with a different brand. It started my car in seconds!!!! I am hoping this one will do the same. I used it to refresh some electronics games and it worked great and keeps a charge for a long time!

Super und Praktische Powerbank
