Several Methods to Charge a Laptop Battery Externally

Assuming your laptop battery is in good condition, you’ll eventually need to charge it to keep working. When using these methods, make sure you are using a cord that will not damage, whether the connection is via USB or adapter. By doing this, the current passing through these connections can be maximized.

Method 1: How to charge laptop with USB Port

In a typical laptop, there are a variety of ports, including a USB-A port for charging devices and transferring data. Unfortunately, this USB type is not designed to provide power for your laptop.  

Charge laptop with USB C

However, if your laptop has a USB-C port, you can use it for power input and to charge your laptop battery efficiently. Additionally, Apple’s MacBook, Asus, Acer, and other laptop brands have adapted USB-C ports to their newer models.

You can always use a USB-C cable instead of an AC/DC adapter. Plug one end of the USB-C cord into an outlet and the other end into your laptop to charge it.

However, this USB-C cable only works with laptops with USB-C ports. There are many older models without USB-C ports. In the meantime, USB-C connectors are becoming more popular and can be found in most new laptops.

Method 2: Externally charge laptop battery Use an External Charger

You can use an external battery charger to charge your laptop battery without using your laptop. Since it’s directly connected to the battery instead of the laptop, it maximizes current flow. 

It only requires you to remove your laptop’s battery and plug it into a compatible external charger. When the battery is fully charged, plug it back into your laptop’s battery slot and turn it on.

It is important to use a charging device that is safe so that injury risks can be avoided and so that your laptop battery can last as long as possible. External chargers with LED indicators and other safety features are more expensive than cheap ones.

Method 3: Use a Universal Power Adapter

Using a universal power adapter is another easy way to recharge your laptop’s battery. If you’re traveling to a country using a different voltage, these adapters are a great tool to have. In spite of this, it’s important to make sure your laptop is compatible with your power adapter because they’re more risky than your original laptop charger.

Almost all tech stores sell universal power adapters, which are an inexpensive option for portable laptop chargers. It’s a legitimate way to provide your laptop battery with some power, but it’s not practical for long-term use. 

If you’re wondering how to charge your laptop battery without a charger, a universal power adapter can help.

Method 4: Charge Laptop from Power Bank

Are wondering how to charge laptop with power bank?

In addition to charging smartphones and similar devices, some power banks can also charge laptops. You can connect your power bank to your laptop via the USB-C port on your laptop. To ensure a consistent supply of power, look for a power bank with at least 10,000 mAh capacity.

An older laptop without a USB-C port is unlikely to support a power bank as a temporary power source.

Method 5: Use Solar to Charge Laptop

Since a long time ago, solar chargers have been available on the market. In these devices, sunlight is converted into electrical energy, which powers the laptop charger. Solar charging kits with smaller photovoltaic cells are known to be more efficient, durable, and portable than older kits. Most modern laptops also support it.
