Review: Best charger I have put on a boat - Hooked this up at the start of the season and it has been absolutely reliable ever since. All three battery banks come up full overnight and the maintenance mode keeps them topped off without overcharging. The build quality is noticeably better than cheaper chargers I have tried before. Review: Does not cook your batteries - Got this 5/5 Guest Charger to permanently install on my Malibu boat with dual starting lead acid batteries. I am loyal to Noco Chargers for all my OHV toys but after reading a ton of reviews saying their Noco marine charger destroyed their marine batteries by over charging and making the acid boil out, I started looking elsewhere. I actually picked the Guest 5/5 charger because of it's color (matched my boat) and it also had great reviews. I've owned it two months now and keep it plugged into the shore power 100% of the time when my boat is not in use. So far, so good! No boiling or otherwise damaged batteries. It switches to maintain mode once the batteries are charged, as indicated by small LED lights on the front that show what it's doing to each battery bank. No need to unplug it during storage. I always turn my boat's battery selector to the "off" position before plugging in the charger. The charger leads attach directly to each battery. You have to purchase the correct "bank number" charger that corresponds to how many individual batteries you want to charge on your boat, RV, etc. For the install, I mounted it near the batteries in the same large compartment. Some people say not to mount in in the area where your batteries are but I open the compartment door so air can circulate. I read that the unit could potentially get warm when charging batteries so I bought a piece of 1/8" aluminum from Home Depot and some 3/8" spacers to create a backing plate against the carpet and spacers to allow airflow behind the Guest charger. Simple install, great investment, and no more worries about my batteries going dead while the boat is in storage. ## Features - Guest On-Board Battery Charger 8A / 12V - 2 Bank - 120V Input [2707A] ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0798G6MYM | | Amperage | 8 Amps | | Best Sellers Rank | #64,943 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #204 in Power Tool Battery Chargers #47,675 in Exercise & Fitness Equipment | | Brand | Guest | | Built-In Media | Battery charger, AC/DC power cables | | Color | Unspecified | | Connector Type Used on Cable | Standard Battery Connector | | Current Rating | 8 Amps | | Customer Reviews | 4.7 4.7 out of 5 stars (2,061) | | EU Spare Part Availability Duration | 2 Years | | External Testing Certification | Não Aplicável | | Global Trade Identification Number | 00046904904082 | | Input Voltage | 120 Volts | | Item Dimensions D x W x H | 2.4"D x 7.5"W x 9"H | | Item Type Name | boating-battery-chargers | | Item Weight | 4.5 Pounds | | Manufacturer | Guest | | Mfr Part Number | 2707A | | Model Number | 2707A | | Number of Ports | 2 | | Output Voltage | 12 Volts (DC) | | Specification Met | ip67 | | UPC | 046904904082 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Guest - **Color:** Unspecified - **Item Weight:** 4.5 Pounds - **Output Voltage:** 12 Volts (DC) - **Product Dimensions:** 2.4"D x 7.5"W x 9"H ## Images ![ChargePro 4/4 - Image 1](https://m.media-amazon.com/images/I/71vAiBT2+YL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best charger I have put on a boat *by M***C on April 2, 2026* Hooked this up at the start of the season and it has been absolutely reliable ever since.
