Very good little charger. Compact and efficient
Excellent. Did the job perfectly. The hook was useful to hang up the charger under the bonnet. Worked well on my dad's mobility scooter. Saved the batteries.

Good build quality I just wish it was a little faster
Having a 95ah car battery this doesnt charge as quick as I would have liked. I should have used the 10% rule and looked for one around 9 - 10 Amps but other than that its good quality. I know I probably should have done my research before buying but I thought for the money it would have some sort of internal switching process for a faster charge to a certain percentage

Good Kit
High quality materials. Very compact unit. Easy set-up. Charging time for completely discharged battery (1.6l Diesel with stop start) 50 % 1/2 hour (maybe enough to start in emergency - I didn't try) 75% 2 hour 100% 4 hour I have no comparison, so up to you to decide if this is good.

Saved me a fortune on a new battery 😊
My Merc doesn’t get used much since working from home has been a thing for over four years now, I found my stop start was non existent (didn’t use it but good to know it works!) and kept getting messages of a low battery. Mechanic said battery was in good condition and to try this charger, so I did! Initially I thought my battery was completely broke, this trickle charged for about 3 days solid, but eventually got to 100%. Took my car out for a drive and the stop start worked straight away. The quality is this product is second to none and it’s IP65 waterproof too, so was easy to hook up my car and shut the hood and leave it to it. Saved me a big bill on a new battery, loads of feature to keep you safe, I’m not particularly mechanically minded but had no fear in using this charger.

Very disappointed
Bought Bosch because I assumed German engineering. Charger stayed on standby mode and did not work. Very disappointed. Returned for refund.

Il prodotto è quello che ho ordinato, mi rendo ben conto venisse da UK, ma essendo stato spedito in Italia pensavo quanto meno ci fosse un adattatore per poterlo usare avendone bisogno.
