RingAutomotive ULTRABOOST 1500A Car Battery Jump Starter - Safely Starts Up to 6 Litre Petrol and 3 Litre Diesel Engines - Battery Booster with Jump Leads, Portable USB Powerbank and LED Torch

This was very easy to use. I looked at two videos specific to my car and using these sort of jumpstart battery thing. The instructions were clear. Sorted in no time.Saves me a lot of hassle and call out fees.

After doing a silly thing and using my automatic tyre inflator on car accessories rather than turning on the engine the inflator soon gave up the ghost and I realised what I had done... the battery on my Toyota Yaris Hybrid was now flat. Because my AA cover had run out calling them out would have been expensive so after doing a little bit of research the solution to my problem was this Ring Automotive ULTRABOOST 500A 12V Car Battery Jump Starter 6000mAh. This is the cheapest in the range but it came highly recommended.It came partly charged so it only took around half an hour to achieve a full charge using the supplied USB-A/USB-C cable plugged into a USB-A mains plug. The two part construction - the main battery and the separate section with the positive and negative leads push together and then you are ready to go.In my specific case the access to the positive battery terminal is underneath the fuse cover. After connecting the red lead to the relevant area (beneath a red safety cover) and then the black lead to a nearby bolt head the unit indicated green meaning it was safe to continue with the jump start routine.It immediately started to provide the necessary power and a distinct click is heard but I did not choose to use the 'boost' function. After 30 seconds I entered the car and pressed the push button ignition start and it fired up... marvellous! The unit can even provide your tablet or phone with instant power.This is a valuable unit and as hybrid vehicles tend to use smaller batteries their onboard electronics can use quite a bit of juice which can be an issue if you are not doing many miles to keep the battery fully recharged. Suffice it to say this gets a full five stars from me... it's well made and certainly a worthwhile investment. Full recommendation.

Was having battery issues and was borrowing a large really heavy (but brilliant) booster to start the car.I should have changed the car battery sooner, but took the decision to get one of these in the meantime and what a revelation.It’s small, neat, in a storage bag and it’s easy to store in the car boot spare wheel & can be charged on the usb cable supplied in the car whilst driving.Importantly - My wife also found it simple to use to and was confident using it … she would never have used the big garage booster!!It did two starts on the one charge and made short work of an absolute flat battery. Mine is a petrol car but says can be used in a diesel up to 1.5ltr … not yet tried it on a diesel.Great piece of kit for those flat battery mornings …Highly recommended 👍

What a product. This item is an exceptional product and good value for money. I was struggling a lot to jump start my car every time it stopped due to the poor battery condition.But since I bought this portable recharger, I don't need to solicit the help of strangers or inconvenience people to help jump lead me every time my car refuses to start.

Ideal piece of kit to have with you when needed. Easily started my flat battery and didn't even take much power from device. Value for money as removes the need for jump cables and someone else's car to give your car a jump. That alone is worth it.

Used to jump start a car that has stood for a while. Started straight away. Easy to use and charge up.

Nicely made. Robust. Bought to jump start my car at the airport after leaving it whilst away on holiday. Just in case, as peace of mind. I leave the bit with the crocodile clips in the car, then I can take the main battery bit with me in my carry on, as a power bank for my devices. What is not to like ? The Ring is 12,000mah, so is within limits for Ryanair. Thanks Ring/Amazon.Note. Already tested it, so I know it actually works well.

I was sceptical when buying this as I have had other booster packs in the past the have failed to start a 2.0l diesel Mondeo. This started the a new shape transit where the battery had gone completely flat. Using the boost button it started to put charge into battery once it had gone from 100% to 80% I tried to start engine and it started first time. Highly recommended.
