The Anker 757 solar generator, also known as the PowerHouse 1229Wh in some regions, has made waves in the market for its promising features. But is it truly a top – tier choice? Let’s take a closer look.
Power Capacity and Output
Ample Energy Storage
The Anker 757 comes with a 1229Wh lithium – iron – phosphate (LiFePO₄) battery. This type of battery is known for its long lifespan and high safety level. With this capacity, it can power a variety of devices. For example, it can run a small refrigerator for several hours, keep your laptop charged during a long work – from – outdoors session, or power LED lights for an extended period during a camping trip. The LiFePO₄ battery also has a long cycle life, capable of enduring over 3000 charge – discharge cycles, ensuring that it will serve you well over the years.
Decent Output Power
It offers an AC output of 1500W, which is sufficient for many medium – sized appliances. You can use it to run a microwave for a quick meal preparation, operate a coffee maker in the morning, or even power a small air conditioner for a short time in case of a power outage. The 1500W output allows for a wide range of applications, both in outdoor and indoor emergency situations.
Charging Capabilities
Fast Self – Charging
One of the highlights of the Anker 757 is its HyperFlash bidirectional inverter technology. This enables the generator to charge from 0 to 80% in approximately one hour when using an AC input. This is significantly faster than many of its competitors. Whether you’re in a hurry to get it charged up for an upcoming outdoor adventure or need to quickly restore power during an emergency, this fast – charging feature is a huge plus.
Solar Charging Compatibility
The Anker 757 is compatible with Anker’s solar panels, such as the upcoming 625 solar panels. When using three of these panels in series, they can generate up to 300W of power, which can charge the 757 to 80% in around three and a half hours. Solar charging provides a sustainable and free source of energy, especially useful for those spending extended periods outdoors or in off – grid locations. However, it should be noted that solar charging times can vary depending on sunlight intensity and panel orientation.
Portability and Design
Compact Yet Sturdy Design
Weighing in at 19.9kg, the Anker 757 is not the lightest solar generator on the market. However, it has a compact design with two molded handles on the sides, making it relatively easy to carry for short distances. The solid plastic housing and two large rubber feet ensure stability, reducing the risk of accidental tipping. The top surface is flat, allowing you to place small devices on it while they are charging.
Clear and Functional Display
The front panel of the Anker 757 features a bright, segmented LCD display. This display shows crucial information such as the remaining battery percentage, input and output power, and the overall health of the device. It automatically turns off after 30 seconds to save power but can be easily re – activated. Additionally, there is a sliding switch for the energy – saving mode, which can be useful when you want to conserve power for essential devices.
Additional Features
Multiple Output Ports
The Anker 757 is equipped with a variety of output ports. It has six USB ports (2C4A) with a maximum output of 100W, which is great for charging multiple smartphones, tablets, and laptops simultaneously. There is also a regulated 120W car charger port for running small 12V appliances. The AC output section offers a combination of two – pin and three – pin sockets, providing versatility for different types of electrical devices.
Emergency Lighting
In case of emergencies, the Anker 757 comes with a multi – function light bar. You can choose from three different light intensities, and by long – pressing the button, it can be set to SOS mode, which flashes at different intervals. This can be a lifesaver during power outages or in emergency situations outdoors.
UPS Function
The generator also has a UPS (Uninterruptible Power Supply) mode. In the event of an AC power grid interruption, it can automatically switch from the main AC input to its internal battery within 20ms. This is extremely useful for devices like desktop computers and 3D printers, where sudden power outages can cause data loss or damage to the equipment.
Drawbacks to Consider
High Cost
The Anker 757 is relatively expensive compared to some other solar generators in the market. Its advanced features, quality components, and long – lasting battery contribute to the higher price tag. However, if you value reliability, performance, and long – term durability, the investment may be worthwhile.
Weight for Extended Mobility
As mentioned, at 19.9kg, it can be a bit heavy for extended carrying, especially during long – distance hikes or if you need to move it frequently. While the handles help with short – distance transportation, it may not be the most suitable option for those who require highly portable power solutions for extreme outdoor activities.
Conclusion
The Anker 757 solar generator offers a compelling set of features, including high – capacity energy storage, fast charging capabilities, multiple output ports, and useful additional functions like emergency lighting and UPS mode. Its LiFePO₄ battery ensures safety and long – term use. However, potential buyers should consider its relatively high cost and weight. If you are looking for a reliable power source for camping trips, outdoor work, or as a backup during power outages at home, and you don’t mind the price and weight, the Anker 757 could be an excellent choice. It provides a good balance between power, functionality, and durability, making it a worthy addition to your power – related equipment.
