Playing keyboards while busking is a great way for musicians to showcase their talents and gain exposure. However, a critical challenge is finding a reliable power source to ensure that their keyboard stays powered up and performs optimally while they play.

In this article, we will explore the various options available for powering keyboards when busking, so musicians have an uninterrupted and enjoyable experience.

Way 1: Using Car Batteries

Using a car battery is a reliable option for powering a keyboard when busking, especially if you plan to perform for a long time. Here are the steps you can follow to use a car battery to power your keyboard when busking:

1. Get the right equipment

1.To use a car battery to power your keyboard, you will need a few pieces of equipment, including a car battery, a power inverter, and a power cable. The power inverter converts the DC power from the car battery into AC power that your keyboard needs to operate.

2. Charge the car battery

2.Before using the car battery, ensure that it's fully charged. You can do this by using a car battery charger.

3. Connect the power inverter to the car battery

3.First, connect the red cable from the power inverter to the positive terminal of the car battery, then connect the black cable to the negative terminal.

4. Connect the power cable to the inverter

4.Connect the power cable to the power inverter's AC outlet. Ensure that the power cable is compatible with your keyboard and has the right plug.

5. Connect the power cable to the keyboard

Connect the power cable to your keyboard.

6. Turn on the power inverter

Turn on the power inverter. If everything is connected correctly, your keyboard should start up without any issues.

7. Monitor the battery level

Once everything is up and running, keep an eye on the battery level of the car battery. You don't want it to run out, or you'll be left without any power.

8. Turn everything off when done

When you're finished with your performance, turn off your keyboard first. Then turn off the power inverter and disconnect everything from the car battery.

Disadvantages should be notice when using car battery to power

Using a car battery to power busking performances can be an effective solution, but it's important to be aware of the potential problems associated with this method. 

While using a car battery as a power source during busking is a reliable and cost-effective option, there are potential problems you should be aware of before using this method.

Firstly, car batteries are heavy, which can make them difficult to transport, especially when combined with other equipment. Secondly, car batteries are hazardous if mishandled or damaged, as they contain chemicals that can be toxic or explosive. Additionally, short circuits can occur if you don't connect the cables correctly, potentially causing damage or posing a fire hazard.

It's also important to remember that car batteries have a limited lifespan. Proper maintenance can help lengthen their lifespan, but eventually, they will need to be replaced. Finally, some keyboards may require a higher voltage or power supply than a typical car battery can provide, so it may not be the best option for all keyboards.

Therefor, using deep cycle batteries is a better way to power.

Way 2: Using Deep Cycle Batteries  

One alternative to using a car battery for busking is a deep cycle battery. Unlike car batteries, deep cycle batteries are designed for continuous use, making them a reliable power source for extended performances.

Here are some benefits of using a deep cycle battery for busking:

1. Longer lifespan:
   Deep cycle batteries are designed to have a longer lifespan than car batteries, even when subjected to frequent deep discharges.
2. Safer:
   Deep cycle batteries are typically safer than car batteries since they contain fewer toxic chemicals that can be hazardous when mishandled.
3. Lightweight:
   Deep cycle batteries are generally lighter than car batteries, making them easier to carry around and transport.
4. More compatible:
   Given their output power, most deep cycle batteries are compatible with most keyboards and other music equipment used in busking performances.
5. Convenient:
   Deep cycle batteries are available in different models, including portable inverter generators and options with built-in charging capabilities, making them a convenient option for buskers.

When selecting a deep cycle battery for busking, it's essential to understand the different types and their advantages and disadvantages. The most common types of deep cycle batteries are flooded lead-acid, sealed lead-acid, lithium-ion, and Lithium Iron Phosphate (LiFePO4) batteries.

While all these batteries have their advantages, LiFePO4 batteries are often considered the best option for busking for several reasons.

Firstly, LiFePO4 batteries are safer than other types of lithium-ion batteries since they have a lower risk of thermal runaway or explosions. They also have a lower risk of fire hazards or toxic gas emissions.

Secondly, LiFePO4 batteries have a longer lifespan than other deep cycle batteries. They can have up to twice the cycle life of lead-acid batteries and last up to ten years, making them a more economical and sustainable option.

Thirdly, LiFePO4 batteries are lightweight and compact, making them easy to transport and handle. They also have a high energy density with a low discharge rate, allowing them to provide steady power for extended periods. For example, a LiTime 12V 50ah LiFePO4 battery weights only 11.57 lbs but with 640Wh energy.

Lastly, LiFePO4 batteries have a wide range of operating temperatures  -20°C to 60°C (-4°F to 140°F), from making them suitable for use in different weather conditions.

Compared to other types of deep cycle batteries like lead acid, the initial costs of LiFePO4 batteries is more expensive, but this kind of battery has long lifespan and other advantages, which makes them a worthy choice. For example, a LiTime 12V 100Ah costs $329.99, but it has 10 year lifespan, making it a cost-effective investment for buskers who regularly perform with their keyboards. This works out to a cost of just $0.09 per day over the battery's 10-year lifespan.

It's important to note that when using deep cycle batteries such as LiFePO4 to power your keyboard, an inverter is also required, just like when using a car battery.

Way 3: Use Portable Power Station

A newer and highly convenient option for powering keyboards during busking is by using portable power stations similar to power banks or chargers used for smartphones. These small devices store energy in batteries and can be recharged via AC outlets or solar panels, making them ideal for outdoor performances.

Portable power stations come in different sizes and capacities and can be charged in several ways. You can charge them by plugging them into a wall socket, through the cigarette lighter port of your car, or through a solar panel. The capacity of the power station you choose will depend on the power requirements of your keyboard and how long you plan to perform.

Conclusion

We have introduced 3 ways to power your keyboard when busking, it’s recommended to use LiFePO4 deep cycle batteries or portable stations.

Deep cycle batteries, such as LiFePO4 batteries, are more durable, safer, and cost-effective options in the long run compared to using car batteries for powering keyboards during busking. They offer the convenience of a portable power source and a longer lifespan, making them a better investment in the long run. LiFePO4 batteries also have a lower risk of thermal runaway or explosions, making them a safer option, especially when handling them during performances. Choosing LiFePO4 batteries from a reputable provider like LiTime will ensure a more reliable and trustworthy option for buskers looking for a dependable power source for their keyboard during busking.

Additionally, portable power stations provide a highly convenient solution for buskers, although their capacity may need to be carefully considered.
Ultimately, the choice of power source should be based on the individual needs of each busker, considering factors such as power output, portability, convenience, and long-term cost-effectiveness.

By selecting a reliable power source, musicians can ensure that their performances are uninterrupted, and they can focus on showcasing their talents while busking.
