Guest On-Board Waterproof Battery Charger | 6A / 12V - 1 Bank (28106)
The Guest 28106 is a reliable, fully automated single-bank on-board battery charger designed for the rugged marine environment. Delivering 6 Amps of charging power, this unit is engineered to provide a high-quality charge and long-term maintenance for a single 12V battery. It is an ideal choice for personal watercraft (PWC), small fishing boats, or as a dedicated charger for a generator starting battery.
Advanced Multi-Stage Charging
The 28106 utilizes a sophisticated microprocessor-controlled 3-stage charging profile (Bulk, Absorption, and Maintenance). This process ensures that the battery is charged quickly to its optimal level and then held at a safe maintenance voltage. This "smart" technology prevents overcharging and plate sulfation, which are the leading causes of premature battery failure in seasonal marine applications.
Key Performance Features
-
100% Waterproof & Shockproof: Rated IP67, this charger is completely sealed to prevent corrosion and can survive being submerged in a meter of water for 30 minutes.
-
3-Stage Charging Technology: Automatically transitions through Bulk (fast charge), Absorption (topping off), and Maintenance (float) stages to extend battery life and prevent overcharging.
-
Universal 12V Compatibility: Optimized for all lead-acid battery types, including Flooded (wet cell) and AGM batteries.
-
Safety First: Includes built-in protection against reverse polarity, over-current, over-voltage, and over-temperature. It is also ignition-protected for safe use on gasoline-powered boats.
-
Compact Footprint: One of the smallest 6A chargers on the market, allowing for installation in tight spaces where larger chargers won't fit.

-
Owner’s Manual & Installation Guide: Detailed instructions covering the 3-stage charging profile and safety warnings.
Key Specs to Remember Before Opening
-
Plug Type: Standard NEMA 5-15 (120V AC).
-
Battery Type Compatibility: Flooded Lead-Acid and AGM only.
-
Protection Rating: IP67 (Dust-tight and waterproof up to 1 meter).
Pro-Tip for Installation
Before you mount the unit, verify that the 4-foot DC leads can reach your battery posts without tension. If they are too short, use at least 12 AWG marine-grade wire for extensions and ensure you use heat-shrink butt connectors to maintain the waterproof integrity of the system.
Installation Tips
-
Mounting: Install in a well-ventilated area. While waterproof, allowing air to circulate around the fins will help the charger dissipate heat more efficiently.
-
AC Connection: The unit comes with a standard 120V plug. For a professional look, many boaters pair this with an AC Shore Power Inlet so you don't have to leave a hatch open to plug in the extension cord.
-
Fuse Protection: The DC output leads come with integrated fanning and fuses to protect the wiring from accidental shorts
Why Choose the Guest 28106?
The 28106 is the perfect "install and forget" solution for boaters who want to ensure their engine starts every time they hit the water. It is a significant upgrade over portable clip-on chargers, offering a permanent, vibration-resistant mount that remains on the boat. It is specifically recommended for Group 24 and Group 27 batteries.
Installation Note:
For the best performance, mount the charger on a flat surface in a location that receives some ventilation. While the unit is 100% waterproof, keeping it away from direct exhaust heat will ensure it operates at peak efficiency during the high-output bulk charging phase.
