Rank #1 in Best Car Battery Charger 2026: 10 Ranked, and Two Share a Model Number
CTEK MXS 5.0 5A Battery Charger with Temperature Compensation
Price and rating as shown on Amazon when we collected them. Both change.
The CTEK MXS 5.0 is a 12-volt battery charger listed at £74.49 in black, and it finished top of this guide. The numbers behind that position are not subtle: 9,676 ratings at an average of 4.8 out of 5, a histogram showing 86 of the ratings at five stars, and a Best Sellers Rank of 2nd in Car Battery Charging Units.
Its own spec table is where things get interesting. The same table lists "Amperage: 5 Amps" and "Current Rating: 110 Amps" - one of those describes this charger, the other does not fit it. It also lists "Input Voltage: 12 Volts" for a unit that is sold as a mains charger, and the only product bullet in the listing says no more than "Genuine Part". Everything on this page is taken from the Amazon listing as published; we have not tested the charger ourselves.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Porsche 718 cayman S sorted.This charger sorted my 1 year old battery in no time. The problem I encountered was a car that couldn't indicate, flash or cruise because the system was too low to give me a total flawless drive every time. After a few hours all systems go including start stop. Great kit. Its a must have”
