This 12V motorcycle battery charger is a must-have for any rider! The 30W fast charging is incredibly efficient, and I love that it works with both lead-acid and lithium batteries—super versatile. The built-in voltage display is clear and accurate, so I always know my battery’s status at a glance. The USB-C port is a great bonus for charging other devices on the go.

This handy little device has a lot going for it. All voltage testing was done with a Fluke 117.- It's very easy to hook up and is entirely automatic. When you hookup a USB-C power source to the input port it starts outputting power in the 12-14VDC range on the battery leads, occasionally dropping to ~8V (seems like it's checking for battery voltage) even if a battery isn't connected. This might be useful for something you have that needs 12V power even if you don't have a battery handy. Once you connect an actual motorcycle battery the charger will slowly ram from ~13VDC up to a ~14.4VDC which is fairly optimal for charging most vehicle batteries. It has green bars that indicate how full the battery is which seem somewhat accurate as the charge cycle progresses.- When charging a USB-C device *from* this unit it requires a 12V power source. You cannot use one USB-C device to charge another with this as a passthrough. In fact you cannot charge any USB-C device while you're charging the moto battery, you have to disconnect the USB-C input to get it to work. Once it does charge though it happily put my Google Pixel into rapid charging, so it is real USB-C spec and not just a port.- It comes with an SAE quick disconnect connector and battery leads which I really like because I don't plan on mounting this to my bike. I have enough stuff on the handlebars already and the plastic mount it comes with seems sufficient for on road use but I ride off road a lot and I'm not sure it could handle the vibration or the inevitable crash. The SAE connector can hang out from under my seat and I can use it for my trickle charger, this charger, or to directly connect to a friend's bike if they need a jump. No need to pull the seat to get to the battery itself.- VERY LIGHTWEIGHT which I absolutely love. I do moto camping and every ounce of weight adds up. The fact that this tiny thing can slip into my backpack but give me the ability to get my bike running or charge my phone in a pinch is huge. It weighs maybe 25% of the USB battery pack I carry. I want to get a 12V solar panel to test with as I think it could make the ultimate combo for off grid use.

The Good:This 2 way USB charger can top off your bike battery from your juice pack, or charge any USB device from your bike battery. It has a convenient meter that shows both the battery voltage and your juice pack voltage along with a bar graph display for charge status. It features an auto shutdown function on discharge and automatic control on charging.It is easily installed by connecting the included SAE pigtail to your battery. It also includes a quick install handlebar bracket. Does a great job charging your battery from a USB source. It is well constructed and a good bargain for a smart two way charger. I did not find any parasitic loss leaving the charger connected to the bike battery.The Bad:Even though drawn correctly on the schematic in the owner's manual the SAE connector polarity is backwards on this device and on the pigtail they provide. If you have an SAE connector on your bike already you will not be able to use it without a polarity reversal adapter. The same goes for using their pigtail with your own trickle charger. On the battery / bike side of the connector the positive should go to the insulated female pin. This prevents the cable from shorting directly to the frame. If you are going to use their connector, you should always keep it plugged into the charger or be sure to prevent it from touching the frame of your bike. Is hopefully in the future they will correct this Iissue, as this is a really great device.

I tried charging my powerbank using the OUT port and didn't notice any change in power level. I'll dink around with it some more and maybe it'll end up working for me. There is a small button between the IN and the OUT ports, which I pressed. Also, I did 'Turn On' the powerbank. The voltage meter and the small green lights all seemed to work. I drove it 15 miles and was hoping for 5% or maybe 10% charge, but so far, zip. I used the PB's built-in USB-C cable. I'll try a stand-alone cable into the PB's USB-C port and see if that inputs power. Fingers crossed.

So my bike already has this but a baisc version that doesnt do reverse charging so its a nice extra feature that i can use it to charge my phone when i ride and will use this to charge my battery instead of the one built into my bike but great idea and does what it says but not fast

Used this to maintain my car battery. Works like a charm. Like the monitor for battery voltage.

The MAXLITHIUM Reverse Motorcycle Battery Charger was extremely easily to set up on my Honda Ruckus in fewer than five minutes. Simple as connecting the Wires to the battery terminals, than connecting the Charger, Cable and Phone. I have a Lithium Battery installed on my Ruckus, and even with the engine off and no key in the ignition, the MAXLITHIUM Charger provides Super Fast Charging to my OnePlus 12. This will be a game changer for longer rides going forward. The Charger itself easily disconnects from the Battery Cables to avoid theft, and attaches quickly and securely to the Ruckus. Great product, highly recommended!
