RAC 400 Amp Rechargeable Jump Start System HP082 - For Car Batteries up to 1500cc, Orange/Red,design may vary

It works ok .

Purchased this RAC NNHP082 Hilka Jump Starter to replace our Silverline Jump Starter & Air Compressor, which was good but the mains charger supplied kept developing a fault. Anyway, here is our experience & thoughts to date with this RAC unit.Product contents:1x RAC NNHP082 Hilka Jump Starter unit.1x Mains battery charger.1x Optional cigarette lighter charger.1x Manual.Likes:+ It works, managed to jump start my car (2.0 GDI).+ Compact & lightweight, it's extremely mobile.+ Easy to place around the engine when using it.+ Button to indicate via a red/green LED light, if there is enough charge in the jump starter battery.+ When charging the unit at the mains, the red LED light comes to indicate it's charging & turns green to indicate when it's fully charged.+ The leads are a decent length, as you place the unit very close to the battery.+ Two 12v outlets for your own accessories such as a light.Dislikes:- Unless your don't like the color orange, there isn't a whole lot to dislike TBH. Perhaps a more straightforward light on the unit would be more useful.Note, make sure you keep the unit charged regularly as it does lose effectiveness over time. So if you plan a drive, charge the unit the night before so it's at full capability.In conclusion, the unit works as expected, love that it's so lightweight & the charging light indicator feature is a neat touch. If anything changes, you'll be the first to know. Highly recommended.

Used twice to start car, now a year after purchase and regular charging no longer holds a charge , so useless .

As far as instruction booklets go, the one with this jump starter is better than most. The unit loses a star rating for two reasons. Firstly, it arrived with just! enough charge to illuminate the battery condition light. Anything less and I think I would have returned it for fear of deep discharge. Secondly, the instructions tell you to charge the unit for a minimum of 18-20 hours, which is fine. But it then goes on to say not to charge for more than 30 hours. Again, this is fine. But! the instructions say that although the battery monitoring system (BMS) should illuminate a green light when the unit is fully charged, "sometimes it may not". The BMS for this engine starter, or any similar product, should be fully automatic. You plug it in to recharge it, and you can walk away, confident that the BMS will keep the charging safe. You also need to recharge this unit at least once every two months, to maintain the battery. I'll keep the unit, mainly due to the RAC branding, and the convenience of the two 12V sockets in the handle. But it is not as idiot-proof and fully automatic as I had hoped. You need to be careful with it.

Existing reviews post this as under -powered for many conventional petrol or diesel engined vehicles, that require a high power surge to turn a cold engine over. I own a hybrid powered vehicle that has a 2.5 litre petrol engine in addition to the electric motor. What most dealers don’t tell you is that theses types of vehicle have a separate “auxiliary” battery to power the system and accessories, such as the locking system, dashboard etc. if you tend to use the vehicle for short journeys - and let’s face it, who hasn’t during various lock-downs during the last 2years - it puts this small battery under abnormal strain. If this battery discharges (as happened to me) you cannot even get into the car! Nothing would work, so I had to gain access using the emergency key. I had to call out roadside assistance. It took the AA man 5 minutes to start the vehicle! All he had to do was attach his battery pack under the bonnet, which immediately enabled the main “system” to power up. Then the huge bank of batteries for the hybrid power took over and the engine started. Leaving the vehicle running for 1/2 hour re-charged the auxiliary battery, so all was well.My point is, that the auxiliary battery is quite small, so a small power pack is more than adequate. This model is quite compact and easily stored in the vehicle for any future emergencies. An absolute must have for any EV or hybrid!BTW the dealer who subsequently checked out the system for me to ensure there were no other underlying problems, recommended regularly trickle charging the auxiliary battery on a regular basis. You try gaining access to this small battery, which in my case is buried in an inaccessible space in the boot. I recommend fitting a trailing charging lead which can be more easily accessed in the boot area, so trickle charging is more easy and convenient!

Replaces an older model. Great replacement and price.

Generally good, but the plastic casing has cracked down the back, where it is thin.
