About this product
Flat battery in a Tesco car park and you're stuck. This jump starter gets petrol engines up to 5L and diesel engines up to 2L going again without ringing breakdown cover. The boost button handles completely dead batteries, so you're not waiting around when you're already late. Safety features stop you connecting it wrong, reverse polarity protection, spark-free design and anti-spike keep things safe while you're hooking it up. The battery clamps reach easily, there's a built-in torch for when it's dark, and it doubles as a power bank with PD30W fast charging for your phone or tablet.
The compact design fits in the glovebox without taking up half the boot. LED status indicators show the charge level at a glance. Charges fully in around 2 hours so it's ready when you need it. Works with most petrol and diesel vehicles on UK roads. The easy-reach clamps make connecting simple even when you're flustered. USB power socket lets you top up devices while you're waiting for help or sitting in traffic.

Great investment works very well. Glad I bought it

Excellent piece of equipment to have.
An excellent piece of equipment, it works really well and is a credit to the manufacturer. It started my car every time until the electrics were sorted. There was no need for a garage call out, a motoring organisation or a friend with jump leads. It stays in the boot now in case it's ever required by myself or someone else I know!

A real life saver
This device has saved me calling the RAC several times. Its been an absolute life saver. Only downside is the instruction manual which is lousy. But just follow the photo on the box. Take a photo of it on your mobile phone.

A right little work horse!
I bought this a while back when I had to jump my car using leads. Since then I had a complete battery failure while away on holiday. This started my car (2L diesel) from dead flat, no dash lights, no central locking, 7 times on one charge a month before. It still wasn't flat. Got me and my family out of a real pickle. It takes up next to no space and would fit easily in the glove box.

Ring 8000mAh Ultraboost Jumpstarter
I used the unit three times during winter: twice for my Kia Picanto and once to help a friend with a flat battery on a Toyota Corolla. The jump starter worked on the first try each time and didn't require a second boost. It is small enough to fit easily under a car seat or in a glove box. On the safety side, it includes protection against reverse polarity, short circuits, and overcharging, which makes operation safe even for inexperienced users. The LED light isn't the strongest, but it helps in dark situations. I haven't tried it as a power bank yet. Overall, I am very satisfied with the Ring 8000mAh Ultraboost Jumpstarter.

The powerbank/output is to charge a mobile phone or tablet.
Make sure the battery pack is charged up before use. Please plug the USB C lead into the hole marked input and the other end into a USB charger, a mobile phone charger for example.
For the RJS020 jump starter, Power Delivery charging is supported up to 30W. This means it can quickly recharge itself and also provide powerful charging for USB-C devices like laptops, tablets, and phones.
Press on/off button to start charging laptop from battery pack.
Plug the intelligent croc clip module into the main battery unit.
Connect the crocodile clips to the battery terminals, within 30 seconds of plugging the battery pack into the clamps.
Press the blue button and the green led should light on the intelligent croc clip module.
Start trying the ignition in 3 second bursts or less.
IF the green led flashes it means the battery voltage is low, you may still be able to get the vehicle to start by pressing the boost override button.
IF the green light is NOT lit at all, it means the battery voltage is low, you may still be able to get the vehicle to start by pressing the boost override button.
Thank you for using Q&A.
