CHARGE IT! 4512 12 V 12/6/2 A smart charger review

The CHARGE IT! 4512 is a portable, single-output 12 V lead-acid charger/maintainer with three selectable charge rates: 12 A, 6 A and 2 A. It sits between the 6 A CHARGE IT! 4506 and the 20 A 4520 in the current portable trio, but it is not simply a higher number on a label: it is a fixed-voltage model with a digital display and a distinct current range. This is a source-based assessment of Clore’s exact product page, shared manual and exact-model image, not a hands-on test.

Fixed 12 V with a choice of rate

Clore identifies the 4512 as a 12 V unit and lists fast, medium and low charging settings of 12 A, 6 A and 2 A. Unlike its sibling 4506, the 4512 does not offer a 6 V selection; the shared owner’s manual specifically notes that only the 4506 has the voltage selector. That clear boundary matters when a garage serves both 6 V equipment and ordinary 12 V vehicles. The 4512 is the stronger fixed-12 V choice, not the more flexible voltage choice.

A higher available rate can be useful when the battery and application permit it, but “12 A” is not a battery-compatibility shortcut. Clore’s manual says small batteries used in motorcycles, jet skis, snowmobiles and lawn tractors should use the lowest possible rate. It says higher rates are appropriate for larger batteries while directing the user to the battery or vehicle instructions for exact charging requirements. Use the selector to follow those directions; do not choose the 12 A setting just because it is the maximum shown. The finder’s numeric threshold likewise measures only the documented top setting.

The exact manual allows standard flooded, maintenance-free flooded, AGM and gel-cell selections. It limits the family to lead-acid batteries and does not provide a lithium program. Though Clore also discusses spiral-wound and deep-cycle applications, those labels do not replace checking the actual battery construction. The sources reviewed for this exact model do not name an EFB or calcium profile, and there is no LiFePO₄ or BMS requirement to match.

Display and maintenance behavior

The product page lists a seven-segment LED display; the original manufacturer image shows the digital face with voltage/charge indicators, battery-type controls, GO button and rate choices. That is a practical contrast with the 4506’s LED progress indicators. It can help a user read the charger’s own status, but it is not a battery tester and does not prove how much usable capacity remains in a vehicle battery.

Clore describes automatic multi-stage charging, soft start, fault protection and a transition to maintenance after the battery reaches full charge. The manual says maintenance can continue until disconnection, and it also directs daily monitoring during extended maintenance. The second instruction is important for anyone considering a long storage connection: this is not permission to leave the charger unattended indefinitely. The 4500 series has a maintenance mode, but Clore’s guidance still calls for periodic attention.

Dry, ventilated, grounded setup

The shared manual specifies a nominal 120 V AC grounded circuit and tells users to keep the charger in a ventilated place, away from the battery’s gas path. It says not to operate in a closed space, not to charge a frozen battery, and not to place the charger where rain, snow or other moisture can drip on it. The manual also requires a marine battery to be removed and charged ashore; on-board charging needs equipment designed specifically for that environment. The 4512 is therefore a portable dry-location charger rather than an outdoor or marine-installed unit.

Clore’s exact page lists a 3.9 lb weight, smart-clamp technology, polarity protection and a one-year limited warranty. But it does not state a battery Ah range or output cable length, and the page/manual sections reviewed do not establish a definitive seller-package inventory. Confirm the exact 4512 part number 141-411-000, the leads in the actual listing and the length needed to reach the battery from a safe outlet. The illustrated unit is exact-model evidence, not proof of every package’s contents.

How to choose between 4506, 4512 and 4520

The 4506 is the one to consider when documented 6 V/12 V selection matters, and its rates top out at 6 A. The 4512 offers more current at up to 12 A but only at 12 V. The 4520 goes up to 20 A, with 10 A and 2 A settings, and is also 12 V only. These are separate configurations, not a shared generic 4500-series recommendation. The right unit depends on voltage, the battery maker’s allowed charging rate, desired current settings and actual installation—not only on the largest amp number.

Shortlist the 4512 for a single 12 V lead-acid battery when its 12/6/2 A choices, digital display and automatic maintenance suit the task. Look elsewhere for a 6 V or 24 V requirement, lithium, multiple independent banks, a published Ah ceiling, rain exposure, or onboard marine use. Before connecting, verify nominal voltage and battery type, use the battery and vehicle manufacturers’ directions, confirm a grounded outlet and dry ventilation, and check the exact seller package and lead reach.
