What You’ll Need to Charge Your Justice Smart Watch
Before we dive into the steps, let’s make sure you have everything you need. Charging your Justice smart watch is easy, but only if you have the right tools.
The Official Charging Cable
The most important item is the charging cable that came with your watch. Justice smart watches typically use a proprietary magnetic charging cable—this means it’s designed specifically for your model. The cable has a small connector that snaps onto the back of the watch, usually near the bottom or side.

Never use a random USB cable or adapter you found lying around. While some third-party cables might fit, they often don’t deliver the right amount of power, which can lead to slow charging or even damage the battery over time. Stick with the original cable for the best results.
A Compatible Power Source
You’ll also need a reliable power source. This can be:
- A wall outlet with a USB adapter (like the one that came with your phone)
- A computer USB port
- A certified USB power bank
Avoid using cheap, uncertified chargers or adapters. These can overheat, deliver inconsistent power, or even pose a fire risk. Look for chargers with safety certifications like UL, CE, or FCC.
A Clean, Dry Environment
Make sure the area where you’re charging is clean and dry. Moisture, dust, or dirt can interfere with the charging connection. If the watch or charger gets wet, dry it thoroughly before plugging it in.
Optional: A Soft Cloth
Keep a soft, lint-free cloth handy. You’ll use it to gently clean the charging contacts on both the watch and the cable. This simple step can make a big difference in charging reliability.
Step-by-Step Guide: How to Charge a Justice Smart Watch
Now that you’ve got your tools ready, let’s go through the charging process step by step. Follow these instructions carefully to ensure a safe and effective charge.
Step 1: Locate the Charging Port on Your Watch
First, turn your Justice smart watch over so you can see the back. You’ll notice a small metal area—usually near the bottom or side—with two or more tiny metal contacts. This is where the charging cable connects.
Some models have a magnetic charging pad that snaps into place, while others may have a small port. Either way, the charging area is clearly marked and easy to find. If you’re unsure, check the user manual that came with your watch or visit the Justice website for your specific model.
Step 2: Prepare the Charging Cable
Take the official charging cable and inspect it. Make sure there’s no visible damage—no frayed wires, bent connectors, or loose parts. If the cable looks damaged, stop using it and contact Justice customer support for a replacement.
Next, clean the metal tips of the cable with a dry cloth. Even a small amount of dust or lint can prevent a good connection. Wipe gently—don’t use water or cleaning solutions unless the manufacturer specifically recommends it.
Step 3: Connect the Cable to the Watch
Now, carefully align the charging cable with the contacts on the back of the watch. The magnetic version will snap into place automatically when it’s close enough. If it doesn’t snap, don’t force it—double-check the alignment.
Once connected, you should feel a slight magnetic pull, and the watch may display a charging icon on the screen. This icon usually looks like a battery with a lightning bolt or a plug symbol. If you see it, great! The watch is charging.
If you don’t see the icon, don’t panic. It might take a few seconds for the watch to recognize the connection. Give it a moment. If nothing happens after 30 seconds, try disconnecting and reconnecting the cable.
Step 4: Plug the Cable into a Power Source
With the cable attached to the watch, plug the USB end into your chosen power source. This could be a wall adapter, a computer USB port, or a power bank.
We recommend using a wall outlet whenever possible. Wall adapters typically provide more stable and faster charging than USB ports on computers, which can be slower and less reliable.
Avoid using public USB ports (like those in airports or cafes) unless absolutely necessary. These can be slow, unstable, or even pose a security risk if they’re designed to steal data (a rare but possible issue with “juice jacking”).
Step 5: Monitor the Charging Process
Once everything is connected, keep an eye on the watch screen. You should see the battery icon fill up gradually. Most Justice smart watches take about 1.5 to 2 hours to charge from 0% to 100%, depending on the model and battery size.
While charging, it’s normal for the watch to feel slightly warm. This is due to the energy transfer and is not a cause for concern—unless it becomes hot to the touch. If the watch gets unusually hot, disconnect it immediately and let it cool down.
You can still use the watch while it’s charging, but we recommend keeping it on a flat surface to avoid accidentally knocking it off or damaging the cable. Also, avoid playing games or using power-hungry features while charging, as this can slow down the process.
Step 6: Disconnect When Fully Charged
When the battery reaches 100%, you’ll usually see a full battery icon or a “Charging Complete” message. At this point, it’s best to unplug the watch.
While modern smart watches have built-in protections to prevent overcharging, it’s still a good habit to disconnect once the battery is full. Leaving it plugged in for hours after charging can generate unnecessary heat and stress the battery over time.
To disconnect, gently pull the magnetic cable away from the watch. Don’t yank it—this can damage the charging port. Then unplug the USB end from the power source.
Tips for Faster and Safer Charging
Now that you know the basics, let’s talk about how to make charging even better. These tips will help you charge faster, protect your battery, and avoid common mistakes.
Use a High-Quality USB Adapter
Not all USB adapters are created equal. A high-quality adapter with at least 1A (ampere) output will charge your watch faster and more reliably. Look for adapters from reputable brands like Anker, Belkin, or Apple (even if you’re not using an Apple device).
Avoid using old or damaged adapters. If the adapter feels loose, gets hot, or has frayed wires, replace it.
Charge in a Cool, Dry Place
Battery performance drops in extreme temperatures. Avoid charging your watch in direct sunlight, near heaters, or in a hot car. Similarly, don’t charge it in humid environments like bathrooms.
Ideal charging temperature is between 50°F and 86°F (10°C to 30°C). If your watch has been in a cold environment, let it warm up to room temperature before charging.
Clean the Charging Contacts Regularly
Over time, dirt, sweat, and oils from your skin can build up on the charging contacts. This can interfere with the connection and cause charging issues.
Once a week, wipe the back of the watch and the charging cable with a dry, soft cloth. If there’s stubborn grime, you can lightly dampen the cloth with water—but never use alcohol, bleach, or abrasive cleaners. Make sure everything is completely dry before charging.
Avoid Using the Watch While Charging (If Possible)
Using your Justice smart watch while it’s charging—especially for games, videos, or GPS tracking—can slow down the charging process. The watch is using power while it’s trying to charge, which creates a tug-of-war.
If you need a quick charge before heading out, it’s fine to use it lightly. But for a full, fast charge, let it rest on a table or nightstand.
Charge Before the Battery Gets Too Low
It’s best to charge your watch when the battery drops to around 20–30%, rather than waiting until it dies completely. Lithium-ion batteries (like the one in your Justice watch) last longer when they’re not frequently drained to 0%.
Think of it like this: shallow discharges are easier on the battery than deep ones. So plug it in when you see the low battery warning, not when the screen goes black.
Troubleshooting Common Charging Problems
Even with the best care, charging issues can happen. Here’s how to fix the most common problems.
The Watch Won’t Charge at All
If your Justice smart watch isn’t charging, try these steps:
- Check the cable: Make sure it’s properly connected and not damaged.
- Try a different power source: Plug into a wall outlet instead of a computer USB port.
- Clean the contacts: Wipe the back of the watch and the cable with a dry cloth.
- Restart the watch: Hold the power button for 10–15 seconds to force a restart.
- Test with another cable: If you have access to another official Justice charging cable, try it.
If none of these work, the battery or charging port may be damaged. Contact Justice customer support for help.
The Watch Charges Very Slowly
Slow charging can be caused by:
- A weak or damaged USB adapter
- A low-power USB port (like on an old computer)
- A dirty charging connection
- Using the watch while charging
Try using a wall adapter with at least 1A output, clean the contacts, and avoid using the watch during charging. If it’s still slow, the cable or battery may be wearing out.
The Charging Icon Doesn’t Appear
If the watch doesn’t show a charging icon, it may not be detecting the connection. Try:
- Reconnecting the cable firmly
- Checking for dirt or debris
- Using a different power source
- Restarting the watch
Sometimes the screen goes dark when the battery is very low. Wait a few minutes after connecting—it may take a moment to wake up.
The Watch Gets Hot While Charging
A little warmth is normal, but if the watch becomes hot to the touch, disconnect it immediately. Overheating can damage the battery or even pose a safety risk.
Let the watch cool down completely before trying to charge again. If it happens repeatedly, stop using the current cable and adapter, and contact Justice support.
How to Maintain Your Justice Smart Watch Battery
Charging isn’t just about plugging in—it’s also about long-term care. Here’s how to keep your battery healthy for years.
Avoid Extreme Temperatures
Heat and cold are battery killers. Don’t leave your watch in a hot car, near a heater, or in freezing conditions. Store it in a cool, dry place when not in use.
Don’t Let the Battery Die Completely
As mentioned earlier, try to charge your watch before it hits 0%. Frequent full discharges can shorten battery life.
Update the Software Regularly
Justice occasionally releases software updates that improve battery performance and charging efficiency. Check for updates in the companion app (if your model has one) or on the Justice website.
Use Battery-Saving Features
Turn off features you don’t need, like always-on display, constant heart rate monitoring, or background apps. These drain the battery faster.
Store Properly When Not in Use
If you’re not using the watch for a week or more, charge it to about 50% before storing. Don’t store it fully charged or fully drained—both can harm the battery over time.
