If you own a portable charger, you probably use it often. Whether at the park or on a road trip, this device can offer a much-needed energy boost anytime. However, if your power bank seems unreliable or won't charge your phone or tablet properly, there are a few warning signs that signal something might be wrong. These include:
Charging indicator light flickers or doesn't light up
If the charging indicator light on your 12v power bank is flickering or not lighting up, it's a sign that there may be an issue with the power bank. The most common reason for this is a bad connection between the charger and its corresponding battery terminals. If you are using a car charger, check to see if your car battery is working properly. If not, have it looked at by a mechanic or replaced as soon as possible before checking into other issues with your 12V power bank.
The electric current tester shows no voltage (0v) when connected, even though the charger is plugged in.
If your electric current tester shows no voltage (0v) when connected even though the charger is plugged in, it's time to change your battery. The best way to tell if this is the case is by using a multimeter or other device that measures the electrical current.
If you don't have access to either of those tools and are still having trouble figuring out what's wrong with your power bank, look at all connections and make sure you're using the right cable and adapter for charging. It could be as simple as plugging into an outlet instead of your car!
You should also check whether or not your power bank still works properly by testing another device with it first before trying again with yours. If both devices work fine, but yours doesn't charge properly after connecting them, something that needs fixing might be wrong inside it.
The device does not start when connected to the power bank.
If you have a 12v power bank with a dead battery, it will not turn on when connected to AC power. It may be completely dead or at the end of its life cycle. In this case, performing a voltage check on the device can help determine whether it is time to replace your power bank or if other problems prevent it from charging properly. If your power bank has low voltage and does not charge when connected to AC power, you may need to change your battery and purchase a new 12-volt DC car charger adapter cable or wall charger (depending on how much money you want to spend).
You may need a new battery if you notice these warning signs.
You may need a new battery if you notice these warning signs.
- The power bank doesn't hold a charge anymore or only charges 20% or less of its capacity.
- The power bank feels warm to the touch after charging for 30 minutes or more (this is normal).
- The charger won't charge your phone or tablet, even when connected properly.
If any of these things happen, try testing your device before you buy another one!
