Rank #8 in Best Car Battery Charger 2026: 10 Ranked, and Two Share a Model Number
Husgw 25A 12V/24V Smart Battery Charger
Price and rating as shown on Amazon when we collected them. Both change.
Two listings in this guide carry the same model number, TK-2500, and the same £59.99 price: this Husgw 25A charger and a rival 25A unit that has collected 77 ratings. This one has collected 5,914, which is the main reason it earns a place here. It is described as a 25A automatic charger for DC12-24V lead-acid and LiFePO4 batteries, with temperature compensation and reverse-connection, short-circuit, overheating and overcurrent protection.
The spec table is where the numbers stop agreeing with each other. Input Voltage is listed as 12 Volts (DC) for a charger whose bullets say it works "via the mains power supply". Battery Charge Time reads 2E+2 seconds - three minutes and twenty seconds - while a reviewer reports a car battery going from 11.3 volts to 14.4 volts in five hours. Everything on this page comes from the Amazon listing, not from any test of our own.
