CRAFTSMAN Wheeled Manual 6A Battery Charger and 175A Starter - Timer

In this review the CRAFTSMAN CMXCESM274 is evaluated as a hands-on solution for anyone who needs both a reliable battery charger and a heavy-duty engine starter. It is aimed at mechanics, weekend DIYers, and small-farm owners who prefer manual control over automated chargers, and the single biggest reason to buy is its combination of a 175-amp engine start with a 25-amp boost mode plus a 135-minute manual timer that lets you control every stage of charging. The unit feels robust and old-school in a good way, delivering fast starts and steady charging for a range of 12V battery types.

Key Features

• 2-in-1 design: Combines a dedicated engine starter and a 6A charger so one unit handles routine charging and emergency starts without swapping gear.
• High starting current: The 175-amp engine start delivers strong cranking ability for stubborn engines and larger displacements.
• 25A boost mode: Quickly restores charge to deeply discharged 12V batteries to get a vehicle or boat ready for a start.
• Manual 135-minute timer: Gives precise control over charge duration and automatically shuts off to avoid overcharging when timing is set.
• Wide battery compatibility: Works with gas and diesel vehicles and supports standard, AGM, gel, and deep-cycle 12V batteries for versatile shop use.
• Durable build and mobility: Steel case, heavy-duty clamps, retractable handle and compact wheels make it suitable for garage or farm environments.

Who It's For

The CMXCESM274 is best for hands-on users who value manual control and heavy-duty starting power: backyard mechanics, small shop owners, and boat or RV owners who need a wheeled unit that can both charge and jump-start a variety of 12V battery types. It is especially useful when you expect to revive deeply discharged batteries or to give a quick boost before starting engines with higher compression.

Those who should look elsewhere include users who need fully automatic, microprocessor-controlled charging, or people who need a compact, battery-powered portable jump starter for roadside use. This is an AC-powered unit that must be plugged in during operation, so it is not a handheld emergency device.

Pros & Cons

Pros

• Robust 175A engine start and 25A boost cover both emergency starts and deep discharge recovery.
• Manual 135-minute timer provides precise control over charging cycles and prevents prolonged charging.
• Sturdy steel construction, retractable handle and wheels make it practical to move around a garage or farm.
• Analog ammeter gives a clear visual of charging activity without relying on complex electronics.

Cons

• Requires AC power during use, so it is not suitable as a portable, battery-powered jump starter for roadside emergencies.
• Some users note mixed opinions on perceived value and clamp size, which may not suit every battery terminal configuration.

Our Verdict

The CRAFTSMAN CMXCESM274 is a solid choice for users who want a durable, manual charger and a serious engine starter in one wheeled package. Its mix of 175A starting power, 25A boost and a precise 135-minute timer make it well suited to garages, workshops, and small farms where AC power availability and moveable equipment are normal. For those who need portable, battery-powered roadside starting or automatic smart charging, a different model is preferable.
