Manscaped Trimmer Won't Charge? - How To Fix It

You're headed for vacation, and you’ve planned a day at the beach. You want to look sleek in your swimwear, with no unsightly hair peeking out from your trunks.

So, you decide to do a speedy trim with your Manscaped trimmer to ensure everything is in order below the belt. But alas, it’s not charging!

Don’t worry, though. That’s what this post is about.

Join me as I explore the four possible reasons why your Manscaped trimmer won’t charge and how to fix it.


Why Is My Manscaped Trimmer Not Charging?

The major culprit for a Manscaped trimmer that won’t charge is usually a faulty charging dock or cable. Other possible causes include a faulty battery, damaged charging pins, and an internal circuitry problem. The trimmer could also be damaged or dead.

In the following sections, I will go through each of these causes in detail, showing you how to troubleshoot and fix the issues.


This post combines my firsthand experience with that of my barber buddies, who own different Manscaped trimmers.

And since experiences vary, I also scoured through customer feedback on different e-commerce sites and barber forums to find users who have encountered this problem.

Let's dive right in.

4 Reasons Your Manscaped Trimmer Won't Charge

1. The Charger or Charging Dock Has a Problem



Like other rechargeable trimmers, your Manscaped trimmer requires a functional charger or charging dock to replenish its battery.


The charging plug, cable, or dock, depending on your specific Manscaped trimmer, can get damaged.

The first thing to check here is if the outlet has power. You can do this by plugging another device into the same outlet to see if it will power on.


Inspect the charger plug and USB cable for any visible damages. However, if the damage is on the inside, it is usually hard to notice.

Instead, try charging the trimmer using a different but compatible USB cable.


If you have the Lawn Mower 3.0 or 4.0 Trimmers, inspect the charging dock.

  • First, check the dock power cable for any kinks, frays, or cuts.
  • Secondly, ensure that the cable is connected securely to the charging dock and the power outlet.
  • Finally, inspect the metal contacts on the dock where the trimmer sits. Check for dirt and corrosion, and if there is a foreign object lodged in the dock.


If the USB cable is damaged, buy another one. On the other hand, if the dock is faulty, contact the brand and inquire if you can get a replacement.

If you are not lucky, find a compatible wireless charger, such as the one in this YouTube video.

If the contacts are corroded, gently clean them with a soft cloth and isopropyl alcohol.


Make sure that you are placing the trimmer correctly in the charging dock, as that’s another cause.


If the charging dock for your Lawn Mower 3.0 is damaged, it’s not a must to buy a new one. Instead, connect the cable directly to the trimmer.

2. The Battery is Dead



Another potential culprit behind a Manscaped trimmer's charging woes is a dead or malfunctioning battery.


Manscaped trimmers are designed with a built-in rechargeable lithium-ion battery. The battery connects to the circuit board on one end, and to the charging pins on the other.

However, several battery-related scenarios can interfere with the charging process.

For instance:

The metal props that connect the charger to the battery could have been disconnected, corroded, or damaged.

Another scenario is when one of the wires to or from the battery is disconnected or damaged.

The worst-case scenario is that the battery could be damaged, particularly from water exposure.

Identification and Solution:


To inspect the battery, you will need to disassemble the trimmer and locate it. 

Then, carefully examine the wires for any signs of damage and the terminals for corrosion.

Also, check if the battery is swollen and test if it's dead.

Unfortunately, if the battery is damaged, it poses a challenge as it is not replaceable. You can only fix damaged wires and loose charging props.


If your trimmer is still covered under warranty, it's advisable not to open it. Instead, contact the brand for assistance.


Exercise caution while disassembling your Manscaped trimmer to prevent damaging its edges, as this could lead to water seepage.

Pro Tip:

To ensure optimal performance and longevity of the battery, it is advisable to occasionally discharge it fully.

3. The Charging Pins are Dirty


Another culprit that I have encountered that can prevent your Manscaped trimmer from charging is loose or disengaged charging pins.


At the bottom of the Lawn Mower 2.0 and 3.0, there are charging pins that connect the charging dock to the battery.


These pins are not soldered to the internal charging circuitry. Instead, they rely on contact, making them a potential weak point.

The problem?

These contacts can become loose or disengage from the battery or charging terminals. In such a case, the trimmer cannot charge.

This is quite common when the trimmer is dropped or experiences an impact.

Identification and Solution:

To determine if this is the cause, you will need to disassemble the trimmer, which is not recommended if it’s still covered under warranty.

Once you have located the contacts, examine them for any signs of corrosion and if they’re loose or disengaged.

If they are dirty or corroded, clean them gently with a soft cloth and isopropyl alcohol.


If they are loose or detached, you might need to reseal or re-solder them.

4. The Trimmer is Dead

While it has not happened to me, I have seen multiple user complaints stating that their Manscaped trimmers died on them.

From most of these comments, it appears that water is behind most of these incidences.


According to Manscaped, their trimmers are waterproof. They claim that their trimmers can safely withstand immersion in fresh water for up to 30 minutes. 


I have come across multiple posts on Reddit, such as this one, where users shared instances of water penetrating their trimmers.

When this happens, the contacts and control board are corroded, which damages the trimmer.

Identification and Solution

To confirm whether water has penetrated the trimmer, you will need to disassemble it.

From there, inspect for signs of water or corroded contacts.

If there is moisture, try wiping it off and drying the components to see if the trimmer will start operating.

I’d also recommend contacting support, as I have seen some users mention that they received a replacement trimmer.

Most Models Affected

Manscaped boasts an impressive lineup of trimmers, but even the finest among them are not invincible to this problem.

Luckily, this guide applies to all of its trimmers, including:

  • The Lawn Mower 2.0
  • The Lawn Mower 3.0
  • The Lawn Mower 4.0
  • The Beard Hedger
  • Weed Whacker
  • Weed Whacker 2.0


Dealing with a Manscaped trimmer that won't charge is the epitome of betrayal by your trusted wingman. Luckily, it's a common problem with simple fixes.

Based on my experience, the most common causes are a faulty charging dock and disengaged charging pins. Other causes include

  • Faulty charging cable
  • The trimmer could be damaged
  • Damaged battery

To identify the culprit, you’ll need to troubleshoot the trimmer, which entails a thorough physical inspection and a gentle shake to ascertain if anything is loose on the inside, as well as disassembling the trimmer.

However, I strongly advise against opening up the trimmer if it's still under warranty, as this may void it. Also, reach out to customer support, as they might offer assistance, including a free replacement or a discount.

I tried all these fixes, none worked. Then I inverted the charging cable (housing alignment slots on opposite sides when plugged in). The unit started charging and working right away. It was a 10 second fix to trim off the tab on the device once I realized this worked.
