The power station market has seen a surge in high-quality options, providing consumers with a range of choices for their portable power needs. One such option is the 70mai Hiker 400, a compact and versatile power station designed to keep you powered up on your outdoor adventures. In this review, we will take a deep dive into the features, performance, and usability of the 70mai Hiker 400 power station.
70mai Hiker 400 Battery Capacity
At the heart of the 70mai Hiker 400 is its impressive 378Wh battery capacity. While not the largest in the market, this power station makes up for it with efficient power utilization. We conducted testing to determine the actual usable capacity of the Hiker 400, and the results were impressive.
On the DC side, we connected a load tester and ran it until the power station reached 0%. With a 120W load, we were able to pull 337Wh of capacity. Resulting in an impressive 89% DC capacity efficiency. This means you can make the most out of the battery when using DC-powered devices. 
For AC devices, we ran the power station from 100% to 0% while measuring the efficiency with a watt meter. Using a crockpot with a power usage of 210W, we obtained a capacity of 320Wh. A 84% AC capacity efficiency. This indicates that the Hiker 400 performs well even when powering higher wattage appliances.
It’s important to note that the runtime of the power station will vary depending on the devices being powered. Powering a 400W appliance will drain the battery within an hour or less. However, with a 120W load, the power station can last for approximately 3 hours, giving you an idea of its endurance.
Charging Ports: Versatility at Your Fingertips
The 70mai Hiker 400 is equipped with multiple charging ports, making it a versatile companion for all your charging needs. On the front panel, you’ll find three USB-A ports, including one Quick Charge port with an 18W output. These USB-A ports are perfect for charging your smartphones, tablets, or other USB-powered devices. 
The standout feature of the Hiker 400 is its 100W Power Delivery USB-C port. This high-powered USB-C port allows for fast charging of laptops, including the Macbook Pro 16″, which can be fully charged in just 1.9 hours. It’s worth noting that most mini power stations settle for a 60W USB-C port, making the Hiker 400 a standout in its category. 
In addition to the USB ports, the Hiker 400 also features a DC cigarette lighter port and a DC 5521 port. These ports provide a 13.6V/10A output, expanding the compatibility of the power station with a wide range of devices.
AC Outlets: Powering Your Appliances
The 70mai Hiker 400 is equipped with two AC outlets capable of delivering 400W of Pure Sine Wave power. This enables you to power a variety of appliances, from small electronics to larger devices. During our testing, we successfully powered a crockpot with a power usage of 215W, as well as a Lasko heater on its low setting, which pulled about 800W.

It’s important to note that the Hiker 400 has a maximum continuous output of 400W. While it can handle appliances that exceed this limit, the runtime of the power station will be significantly reduced. We recommend sticking to appliances within the 400W range for optimal performance and longevity.
The AC outlets also feature an 800W surge capacity, providing additional power for devices with high startup power requirements. This ensures a stable power supply, even during peak loads.
