The Renogy 20A AC-to-DC Charger is an automatic, portable charger intended for 12V Lithium-iron phosphate (LFP) batteries. It includes 12AWG alligator clips and outputs power based on the battery's power, voltage, and current condition. The unit's status indicator light illustrates the connected battery's operating mode and condition. The Portable LFP charger automatically monitors and maintains the battery at full charge.
| PRODUCT HIGHLIGHTS |
| Lithium Battery Activation |
When the lithium battery encounters low temperature/low voltage, the BMS protection will be triggered, and charging cannot be performed. This charger provides a lithium battery activation function that quickly exits the protection mode and recharges. The charger's indicator light can remind the wrong charging status and achieves all-round monitoring and protection. |
| Smart Charging |
The charger has a 3-stage intelligent charging design: high current (cc), constant voltage (cv), and trickle. It can accurately identify battery voltage and automatically switch charging mode and provide fast and efficient charging for lithium batteries; the charger's efficiency can reach up to 92%. |
| Strong Adaptability |
The charger comes with one battery charging cable, the alligator clips suggested for short-term use. The battery charger has a wide AC input voltage range, 100-240 VAC 50/60Hz, which is compatible with AC power grids in different countries to meet the needs of fast charging anytime and anywhere. |
| Build-in Safety Protection |
The charger has six built-in protection functions to ensure charging safety, including short circuit protection, over-current protection, over-temperature protection, over-voltage protection, under-voltage protection, and reverse polarity protection. The charger's indicator light can remind the wrong charging status and achieves all-around monitoring and protection. |
| Silent and Efficient Heat Dissipation |
The product uses a patented plastic profile design, and the shell itself can achieve rapid heat dissipation. The fan-less design brings users a zero-noise charging experience and reduces concerns about the installation angle and space of the product. |
| Easy to Use |
3-quick-step to quickly establish the connection of battery and charger, the steps are as follows: 1. Connect the negative output terminal of the charger to the negative terminal of the battery 2. Connect the positive output terminal of the charger to the positive terminal of the battery 3. Connect the AC Charger Power Adapter Cable to the AC port of the charger |

What kind of batteries is suitable for this charger?
This charger is specially designed for lithium battery charging. It is a 12V dedicated lithium battery charger, specifically tailored for 12V lithium iron phosphate batteries.
Can this charger wake up a lithium battery that triggers BMS protection?
Yes, this charger has a lithium battery activation function. When the lithium battery cannot be charged and discharged after triggering the BMS protection, this charger can be used to wake up the lithium battery.
What capacity of the batteries does this charger support?
The charging current of this charger is 20A. When using it, you need to make sure the maximum charging current of the battery is ≥20A. The total charging time for a 100Ah lithium battery is 3.5 hours.
What are the accessories for this charger? What functionality does each provide?
Accessories for this charger include an alligator clip battery cable and a Blade Fuse. The battery cable provides an easy-to-operate connection method to facilitate the user in quickly connecting the charger to the battery. The Blade Fuse serves to provide reverse connection protection for the battery. If the charger's positive and negative output terminals are accidentally reversed, only the fuse will burn, ensuring the safety of the AC charger and providing double protection.
What are the phenomena of this charger in different charging stages?
When the charger is in the fast high-current charging stage, it will provide a maximum charging current of 20A, and the charger's indicator light will slow flash red, indicating that it is charging.
When the charger is in the constant voltage charging stage, the charging current will continue to decrease to 2A, and the charger's indicator light will slow flash red, indicating that it is charging.
When the charger is in the trickle phase, the charging current will be less than 1A, and the charger's indicator light will be green, indicating that it is fully charged.
