As the seasons change, you might be getting ready for your very first mobile pop-up with your permanent jewelry business. You’ve packed your delicate chains, dainty charms, and most importantly—your pulse arc welder. Everything feels set for a great day out at a bustling market. But then it hits you… there’s no power outlet in sight. So how are you supposed to run your welder?

Top 3 Power Supply Banks for Permanent Jewelry Artists
With so many power supply options out there, it’s easy to feel overwhelmed. That’s why I’ve narrowed this review down to the top three power banks that permanent jewelry artists actually use and trust. Over time, the 300-watt model—across a few different brands—has become the go-to standard. It hits the sweet spot: powerful enough to run your tools, but still portable and efficient. I’ll break down each option so you can see why these are the favorites among pros in the field.
1. Jackery Explorer 300 (Most Popular)
The Jackery Explorer 300 has earned its spot as a favorite in the permanent jewelry world—and for good reason. It’s reliable, high quality, and delivers clean, consistent power for everything from your pulse arc welder to your phone and overhead lamp. With a 293Wh battery and 300 watts of output through two pure sine wave AC outlets, it’s more than enough to keep your setup running smoothly. Plus, it’s super portable at just over 7 pounds—perfect for outdoor markets and pop-ups.
One thing I love about the Jackery? It charges fast. You can get it up to 80% in around two hours using a wall outlet and the 60W USB-C port. That’s a lifesaver when you’re in between events and need to power up quickly. It also supports charging via car outlet or even solar (if you have the Jackery SolarSaga panel), which is ideal for eco-conscious artists or those who work mostly outdoors.
Yes, it’s a bit of an investment—but if you’re serious about your business, it’s worth every penny. You can power up to six devices at once, which comes in handy during busy events. If you want something dependable and flexible enough to grow with your setup, the Explorer 300 is a solid choice.

2. Grecell T300 (Most Affordable)
The Grecell T300 is another solid pick for permanent jewelry artists who need reliable power on the go. It’s got a 288Wh capacity and 330W output (with a 600W surge), which is more than enough to run your welder, phone, lamp, fan, tungsten sharpener—you name it. And because it’s lightweight and easy to carry, it’s perfect for hauling to outdoor markets or events.
What makes it stand out is how safe and efficient it is.

Personally, I’ve had a great experience using the Grecell T300 at my own events. Being able to run up to eight devices at the same time keeps everything flowing smoothly, even on my busiest days. And the fact that you can recharge it via wall outlet, car, or solar panel? Total bonus. For the price, it packs a punch—and it’s become one of those tools I wouldn’t do a pop-up without.

BLUETTI backs it all with an impressive 5-year warranty, which gives some extra peace of mind. If you’re looking for something that’s efficient, durable, and packed with tech, the AC2A is definitely worth a look.
Understanding Power Supply Banks
A power supply bank—also called a portable power station or battery generator—is basically a rechargeable battery that lets you plug in your tools when you don’t have access to an outlet. It stores energy and gives you power through ports like USB, AC, and DC. You can recharge it at home, with solar panels, or even in your car. For permanent jewelry artists doing pop-ups in parks, vendor tents, or anywhere off-grid, it’s a total game-changer.
Power Supply Banks Versus Traditional Generators
Portability: Power supply banks are compact and lightweight, designed for easy transportation with a durable casing and a handle, making them ideal for outdoor business activities and recreational use. In contrast, traditional generators are bulkier and heavier, and they are not designed to be carted around. Even though portable models are available, they tend to be more cumbersome and less convenient to transport compared to power supply banks.
Noise Levels: One of the significant advantages of power supply banks is their quiet operation. They store and release power from a battery, operating silently, which makes them ideal for settings where noise is a concern, such as public events or crowded markets. Generators, on the other hand, are known for being noisy; they run on gasoline or diesel and produce a considerable amount of sound while operating, which can be intrusive in quiet environments.
Power Output: Power supply banks are generally suited for lower power demands and are perfect for charging phones, running lamps, and powering tools like pulse arc jewelry welders with moderate energy requirements. Typically, their output ranges from 100 to 1000 watts, making them suitable for devices that can tolerate these power limits. In contrast, generators offer a more robust power output and can handle much higher energy demands. They can power entire setups, including large appliances and multiple heavy-duty tools simultaneously, with their output often reaching into thousands of watts, catering to more intensive energy needs.

Importance of Wattage
Wattage is a measure of electrical power expressed in watts (W). It represents the rate of energy transfer. In simpler terms, wattage tells you how much power an electrical device consumes or can supply per unit of time. This measure is crucial when selecting power equipment because it helps you match the power supply’s output with the energy demands of your devices to ensure efficient and safe operation.
Determining Appropriate Wattage for Your Permanent Jewelry Welder: To determine the right wattage for your jewelry welder, you need to look at the specifications provided by the manufacturer, usually found in the product manual or listed on the device. The wattage requirement will tell you the amount of power needed for the welder to operate optimally. It’s essential to choose a power supply that will meet or exceed this wattage without being so powerful as to risk damaging the device.
Wattage Requirements for Common Permanent Jewelry Tools:
Jeweler’s Lamp: Lamps used to light your workspace can vary in their wattage requirements depending on the brightness and type. The Canvas lamp I use is LED with 1,200 Lumens, so it requires only 18 to 30 watts. A traditional incandescent or halogen bulb would require 100+ watts.
Smartphone for Taking Payments: Smartphones usually require very little power compared to larger devices, typically around 5 to 20 watts. It’s important to ensure your power source can handle this small but critical load, especially over extended periods, to maintain payment processing capabilities throughout your event.
Handheld Tungsten Sharpener: These devices typically require between 50 and 100 watts. Keep in mind that you’ll only need to use the sharpener occasionally, so you can always unplug your lamp or smartphone to free up the power needed.

Assessing Battery Duration
To calculate how long a power supply bank can power your equipment, you’ll need to understand two key figures: the capacity of the power bank (measured in watt-hours, Wh) and the power load of your equipment (measured in watts, W). The formula to estimate the duration for which the power supply can run your device is:
Duration (hours) = Power Load of the Device (W) / Capacity of the Power Supply (Wh)
For example, if your permanent jewelry welder requires 30 watts and your power supply bank has a capacity of 300 watt-hours, the duration would be:
Duration = 300 Wh / 30 W = 10 hours (of continuous use)
Tips to Extend Battery Life During an Event:
- Prioritize Equipment: Only use essential equipment and turn off or unplug devices when not in use.
- Energy-efficient Tools: Opt for tools that require less power or have energy-saving features, like LED lights versus incandescent or halogen.
- Monitor Usage: Keep an eye on the power supply’s display, if available, to track usage and manage your power reserves better.
- Adjust Settings: Lower the settings on devices that allow it, such as reducing the brightness on a lamp.
- Environmental Factors: Keep the power supply in a cool, shaded place, as excessive heat can reduce battery efficiency.
Importance of Backup Power Options: Having backup power options or a strategy for recharging your power supply is crucial, especially during multi-day events. Here are a few strategies:
- Extra Power Supply Units: If feasible, carry an additional fully charged power supply bank.
- Solar Panels: Some power supply banks can be recharged via solar panels. This can be an excellent method for outdoor events where you can harness solar power throughout the day.
- Vehicle Charging: If your setup is near a vehicle, consider a power bank that can be charged using a car’s battery system.
- Scheduled Downtime: Plan a mid-day break or rotating usage schedule to allow time for recharging equipment without losing productivity.
- Recharge Overnight: If you are doing a week-long event, make sure to bring your device home or back to your hotel room and recharge it for the next day, even if it has more than 50% charge left.

Evaluate Your Power Needs and Choose One
If you’re doing outdoor pop-ups, having a solid power supply bank isn’t just helpful—it’s essential. You need your welder, lamp, and payment processor to run smoothly so you can focus on what you do best: creating beautiful pieces and connecting with your customers—not stressing about where the nearest outlet is.
As we’ve seen, not all power banks are created equal. Things like capacity, size, and wattage can really impact how well one fits your setup. For most permanent jewelry artists, something in the 300-watt range hits the sweet spot. Any of the top models we’ve talked about can handle typical event needs, but it’s still worth checking what your tools actually draw and how long you’ll be using them.
At the end of the day, the best power bank is the one that matches your workflow and helps you show up confidently, no matter where you’re set up. Pick the right one, and your next pop-up won’t just run smoothly—it’ll shine.
