High-Capacity Lithium Power in a Small Package
At its core, the Southwire Elite 300 Series houses a 296Wh lithium-ion battery, providing an ideal balance between portability and performance. For a device weighing just over 7 pounds, it delivers more than enough power to recharge a laptop 4–5 times, a smartphone 20–30 times, or keep a CPAP machine running through the night.
Lithium-ion batteries are known for their durability, high energy density, and long cycle life. Unlike older lead-acid power banks, lithium batteries are lightweight, charge faster, and are less prone to power degradation over time. Southwire’s decision to use UL-certified lithium cells ensures an added layer of safety and reliability, especially important for use in sensitive environments or enclosed spaces like tents or bedrooms.
Quiet, Clean, and Emission-Free Power
One of the standout advantages of this unit is its completely silent operation. The Elite 300 doesn’t use an internal combustion engine, so there’s no fuel, oil, or fumes to worry about. Instead, it operates with an internal cooling fan and emits no carbon monoxide—making it safe for indoor use, unlike traditional gas generators.
This makes it perfect for:
- Tents and campers
- Apartments during blackouts
- Quiet outdoor settings (like national parks)
- Emergency medical equipment, like CPAP machines
The Pure Sine Wave inverter also guarantees stable voltage output, which is especially important for protecting sensitive electronics such as laptops, TVs, and smartphones.
User-Friendly Controls and LED Display
Ease of use is central to the design of the Southwire Elite 300 Series. The front-facing control panel includes:
- A bright LED digital screen showing battery percentage and real-time watt usage
- Clearly labeled buttons for AC and DC output
- Dedicated power on/off button
- USB-C and USB-A ports for modern and legacy device compatibility
The intuitive layout allows even first-time users to quickly understand power draw, battery status, and estimated runtime—all critical details during emergencies or extended trips.
Multiple Output Options for Varied Needs
The Elite 300 is designed for flexibility. It features the following output ports:
- 1x Pure Sine Wave AC outlet (300W continuous, 600W surge): Great for laptops, fans, projectors, CPAP machines, or mini-fridges.
- 2x USB-A ports: Suitable for charging smartphones, cameras, flashlights, or GPS devices.
- 1x USB-C port: Offers fast charging for tablets, newer phones, or portable game consoles.
- 1x 12V car port: Ideal for small automotive accessories or 12V-powered camping gear.
This makes it a well-rounded choice for everything from camping trips to disaster relief scenarios.
Three Ways to Recharge
One of the more flexible features of the PEP-S300 is its multiple recharging options. You’re not limited to wall power—you can also recharge via your vehicle or with solar panels. This allows true off-grid capability.
- AC Wall Charging – Included adapter charges the unit in approximately 5–6 hours.
- 12V Car Charging – Using the included car charger, it can recharge in 6–7 hours while driving.
- Solar Panel Charging – Compatible with most third-party solar panels (18V input range). Built-in MPPT (Maximum Power Point Tracking) controller increases solar charging efficiency.
This flexibility makes it ideal for extended outdoor use or regions where power is unstable or unavailable.
Real-Life Applications: Where the Elite 300 Shines
The Southwire Elite 300 Series isn’t just for one type of user. Its portability, clean power output, and flexible charging options make it useful for a wide variety of real-world situations:
1. Camping and Overlanding
