What owners report
We have not reviewed owner feedback for this product.
Known issues and safety
Recall check: we searched GOV.UK product safety alerts, reports and recalls (Office for Product Safety and Standards) for “grepro” on 19 October 2026 and found no results [3]. Jump starters and power banks do appear on that list for other brands, so check it again for the exact product before you buy.
We could not find a manual we could cite, so we cannot summarise the maker’s safety instructions. Follow the instructions supplied with the unit. The RAC says to check the pack is fully charged first and not to place it on the engine [4].
Questions people ask
What engine size is it rated for?
The listing title says up to 4.5 litres petrol and 2.5 litres diesel [1]. We could not confirm that against a maker’s page. See our guide on what size jump starter you need.
Is it a power bank as well?
The listing title says it includes a 10000 mAh power bank [1].
Is this model on GREPRO’s website?
No. GREPRO’s site lists larger 4000A to 7000A models [2], so the specification above rests on the marketplace seller’s listing only.
Alternatives
- NOCO Boost Sport GB20: Rated for petrol up to 4.0 litres by a UK seller. See our separate page.

Our verdict
Based on the evidence, this suits drivers of small and medium cars who accept a marketplace seller’s rating. We cannot confirm the engine rating, peak current or protections from the maker. This is a research summary, not a test result.
