It’s worth noting that Harbor Freight frequently runs promotions and sales events where you might find these inverters at even more competitive prices. I’ve seen the 175-watt model drop to $29.99 during special events, which represents extraordinary value for a portable power solution.
These price points position Bauer inverters as more affordable alternatives to premium brands like Jackery or Goal Zero, whose comparable models often cost significantly more. While those brands offer certain advantages, the price-to-performance ratio of Bauer inverters makes them particularly attractive for budget-conscious consumers who still need reliable power.
Where to Purchase Bauer Inverters
If you’re looking to add a Bauer inverter to your power arsenal, your primary destination will be Harbor Freight Tools. As Bauer is Harbor Freight’s exclusive in-house brand, their stores are the official retail outlets for these products. With over 1,300 locations across the United States, finding a nearby Harbor Freight store is relatively easy for most Americans.
For those who prefer online shopping, Harbor Freight’s website offers the complete range of Bauer inverters with detailed specifications and customer reviews. They frequently provide free shipping on orders over a certain threshold, making this a convenient option if you’re not in a rush.
While some third-party marketplaces might list Bauer products, I’d recommend purchasing directly from Harbor Freight to ensure you’re getting an authentic product with full warranty coverage. Additionally, Harbor Freight often includes valuable extras like discount coupons for future purchases when you buy directly from them.
Portability: Taking Power Wherever You Go
One of the most appealing aspects of the Bauer inverter lineup is its impressive portability. The 175-watt model, in particular, is extraordinarily compact, measuring roughly 6″ × 3.5″ × 2″ and weighing less than two pounds. This makes it small enough to slip into a backpack pocket or glove compartment without adding significant bulk or weight.
Even the more powerful 800-watt and 1200-watt models maintain reasonable portability, with the 1200-watt version weighing approximately 5 pounds. The 2000-watt inverter, while naturally larger and heavier at around 8 pounds, remains transportable for situations where maximum power output takes priority over ultra-portability.
The excellent power-to-weight ratio makes Bauer inverters ideal companions for camping trips, tailgating events, or emergency preparedness kits. I’ve found the 800-watt model strikes a particularly good balance for most outdoor recreational activities—powerful enough to run essential devices but compact enough to transport without hassle.
Battery Compatibility: Powering Your Inverter
A key consideration for any portable inverter is its battery compatibility. The Bauer inverter line offers impressive flexibility in this regard, with multiple connection options depending on your power source.
For vehicle integration, all Bauer inverter models include standard 12V DC cables that can connect directly to your car, truck, RV, or boat battery system via the cigarette lighter port (for smaller models) or direct battery clamp connections (for higher-wattage options).
For the ultimate in portable convenience, the 175-watt model can indeed work with Bauer 20V lithium-ion batteries with an optional adapter. This compatibility with the same batteries that power Bauer cordless tools creates a convenient ecosystem for those already invested in the Bauer tool platform. Imagine running your laptop or charging your phone using the same battery that powers your drill—that’s the kind of practical integration that makes these inverters especially valuable.
When connected to a fully charged Bauer 20V 5.0Ah battery, the 175-watt inverter can typically provide:
- Approximately 3-4 hours of smartphone charging
- About 2-3 hours of tablet use
- Roughly 1-2 hours of laptop operation (depending on the laptop’s power requirements)
For the larger inverter models, you’ll need more substantial power sources like deep-cycle marine batteries or dedicated power stations for extended off-grid use.
Device Compatibility: What Can You Power?

It’s worth emphasizing that while an inverter might be rated for 2000 watts of continuous power, many appliances require a higher “surge” wattage during startup. The Bauer 2000-watt inverter provides a peak surge capacity of 4000 watts, which should accommodate the startup requirements of most appliances within its continuous power rating.
Connectivity Options: Powering Modern Devices
Modern device charging requires versatile connection options, and the Bauer inverter line doesn’t disappoint. All models feature at least one standard AC outlet (the North American 3-prong variety), while the larger models offer two or more outlets for powering multiple devices simultaneously.
USB connectivity is a crucial feature for today’s tech-centric world, and Bauer has recognized this need. Most models in the lineup include USB-A ports delivering 2.1 amps of power—sufficient for charging smartphones, tablets, Bluetooth speakers, and similar devices. The newer models also feature USB-C ports with Power Delivery support, capable of faster charging for compatible devices.
The interface design across the lineup is straightforward and user-friendly, with clear LED indicators showing power status, battery level, and warning notifications for issues like overheating or overloading. This intuitive design makes Bauer inverters accessible even to those with limited technical experience.
Runtime: How Long Will It Last?
Battery life is perhaps the most variable aspect of portable inverter performance, as it depends heavily on both the power draw of connected devices and the capacity of your power source. However, we can provide some general expectations based on common scenarios.
When connected to a typical car battery (while the engine is running to allow recharging):
- The 175-watt inverter can run indefinitely for most small devices
- The 800-watt inverter can sustain operation of medium-sized devices
- The 1200-watt and 2000-watt models should be used more judiciously, as they draw significant power
When connected to a standalone 100Ah deep-cycle battery:
- A 175-watt inverter powering a 50-watt laptop might run for approximately 15-20 hours
- An 800-watt inverter powering a 200-watt device might operate for about 4-5 hours
- The 1200-watt inverter at half load might function for roughly 2-3 hours
- The 2000-watt model at full capacity might deplete a 100Ah battery in about an hour
These estimates assume optimal conditions and new batteries. Real-world performance will vary based on battery condition, temperature, and the specific characteristics of connected devices.
Safety Features: Protecting Your Devices
When it comes to powering sensitive electronics, safety features are non-negotiable. Bauer inverters incorporate multiple layers of protection to safeguard both your devices and the inverter itself—a critical consideration that budget inverters sometimes overlook.
All Bauer inverter models include:
- Overload protection that automatically shuts down the inverter if power demands exceed its rated capacity
- Short-circuit protection to prevent damage from wiring faults
- Over-temperature protection that reduces output or shuts down the unit if it begins to overheat
- Low-battery alarm and automatic shutdown to prevent completely draining your power source
- Cooling fans that activate as needed to maintain optimal operating temperature
These protection systems are particularly important for sensitive electronics like laptops, phones, and cameras, where power fluctuations can potentially cause damage or data loss. The pure sine wave output on higher-end Bauer models provides power that closely mimics utility-supplied electricity, making them suitable for sensitive medical equipment and high-end electronics that might malfunction with the modified sine wave output found in cheaper inverters.
Durability and Build Quality
While Bauer tools are positioned as a value brand, the inverter line demonstrates solid construction that should withstand typical use scenarios. The housing is constructed from impact-resistant materials with rubberized corners on some models to absorb shocks from accidental drops or bumps.
For outdoor use, it’s important to note that Bauer inverters aren’t formally rated for water resistance. While they can certainly handle outdoor environments in fair weather, you’ll want to protect them from direct exposure to rain, snow, or excessive moisture. This limitation is fairly standard across inverters in this price range.
The cooling systems incorporate dust-resistant fan designs that help maintain performance in dusty environments like construction sites or dusty campsites. The internal components are well-secured to resist damage from vibration during transport—an important consideration for an inverter that might spend significant time in a moving vehicle.
Connection points represent a common failure area in cheaper inverters, but the Bauer models feature reinforced power sockets and robust input terminals that should maintain reliable connections throughout the product’s lifespan.
