Ring UltraBoost 1500A jump starter review

Overview

The Ring UltraBoost 1500A ranks #7 in our list of the top 10 best-selling portable jump starters on Amazon UK, with a score of 8.6/10 and our Best display and cable reach award. It is a mid-range option for drivers who want a recognisable UK automotive brand, a clear charge readout and flexibility around battery terminals. Ring rates it for engines up to 6.0L petrol or 3.0L diesel, though those figures are manufacturer claims rather than a guarantee for every vehicle or battery condition.

In our ranking, it sits below the NOCO Boost GB70, our premium best overall pick, and the mid-range NOCO Boost GB40. The Ring’s appeal is its LCD and claimed extended clamp-cable reach; check the GB40 or GB70 listings too if you are comparing options, as the right choice depends on your vehicle and preferred features.

Features and specification

The listing specifies a 12,000mAh lithium-ion battery and 1,500A peak current. Its LCD shows battery status and remaining charge, making it easier to check the pack before storing it in the car than a basic indicator alone. Spark-free operation and surge protection are also listed, alongside warning alerts and a boost function intended to help with very depleted batteries.

Ring says the longer clamp leads allow more flexibility when reaching terminals in awkward positions. That may be useful in larger vehicles or where the battery is not easy to access, but it does not remove the need to follow the supplied instructions and connect the clamps correctly. The listing gives a one-year warranty. It does not establish a water-resistance rating or clearly confirm features such as a torch or USB output, so do not choose it on the assumption that it has those extras.

Independent reviewers at What Car? note the display, quality feel and high peak-current figure, while also pointing out that the unit takes up more room when connected. Their assessment offers useful context, but it does not replace checking compatibility with your own vehicle.

What owners say

Early owner feedback is encouraging. Buyers describe the unit as straightforward to connect and report successful starts on cars and vans, including some diesel and stop-start vehicles. Several also appreciate its compact form, sturdy feel and supplied storage pouch, which helps keep the pack and accessories together in the boot.

There are caveats. Some owners would like more cable length despite the advertised extended reach, so the leads may still feel restrictive depending on where your terminals sit. One buyer found the first full charge slower than later top-ups. Reports of successful starts are useful, but they are individual experiences and do not guarantee the same result with a severely damaged battery or an incompatible vehicle.

Who should buy it

Consider the Ring UltraBoost 1500A if you want a portable jump starter from an established automotive brand, value an LCD charge display and need extra reach around the battery area. Its stated engine limits cover many family cars, SUVs and vans, and the safety features may suit drivers who prefer clear alerts and a boost function.

Skip it if you need extensive long-term owner feedback, a confirmed water-resistance rating or clearly specified torch and USB functions. Before buying, check the requirements in your vehicle handbook and compare the clamp reach with your battery layout. The Ring is a sensible, feature-focused middle ground, but its cable length and accessory details deserve a final check.
