If you’re searching for a power station, you have quite a few things to consider, and I’m talking more than battery capacity and output power. Power stations have advanced in recent years, and because of that, you have to consider more things, such as design when it comes to the screen, whether the power station is compatible to use with an app, the type of battery it uses, and a few other things.

I’m looking at this 70mai Tera 1000 power station in this review. The Tera 1000 is a powerful portable power source that can fit most people’s needs and has a few features that I wasn’t expecting from 70mai. Let’s take a closer look.

Battery Capacity

The battery capacity for this Tera 1000 power station is 1043Wh, and this is a lot of power to use depending on what you want to power. That said, what matters most is efficiency, capacity, and how much you can use. That is why I ran a DC and AC capacity test.

For the DC capacity test, I powered my load from the cigarette lighter port on this power station; I ran the power station from 100% to 0% on a 120W load with the load tester. Ultimately, I got an 848Wh DC capacity, which gave me an 81% DC capacity efficiency. This is good so that you can use most of the capacity on the DC side for this Tera 1000.

I powered a heater on its low setting for the AC capacity test, pulling about 750W of power. I used a watt meter to measure the watt hours and ran the heater with the power station from 100% to 0%. I ended up with an 830Wh capacity for the AC capacity, which gave me about 79% AC capacity efficiency. So the AC capacity is slightly lower than the DC one, but that is expected.

Overall, the capacity efficiency of this Tera 1000 power station is good, not excellent, because that would mean the efficiency would be in the 90% range. In terms of runtime, that will depend entirely on the device you’re powering from the power station. My DC capacity test lasted about 7 hours, with a 120W power draw.

So if you stick within the 200W –  300W range, you can use this power station for a couple of hours.

Charging Ports

The Tera 1000 power station does have two DC 5521 ports and a single cigarette lighter port that can output 13.6V/10A; I did not have any devices that were compatible to use with the DC ports, but I was able to pull 120W from the car socket when I did the DC capacity test.

The charging ports include a standard 12W USB-A port, a Quick Charge USB-A port, an 18W USB-C Power Delivery port, and a 60W USB-C PD port. So the ports are good, but since this is a power station on the higher-end side, I would have expected at least a 100W PD USB-C port.

For my charging port test, I could charge my Basues power bank 62W from the 60W USB-C port and fast charge my Note 9 from the 18W USB-C port. So the charging ports work how they’re supposed to, and you can charge most USB-C chargeable laptops from the 60W USB-C port, which is helpful rather than using a wall charger on the power station.

AC Outlets

There are a total of three AC outlets, and each of them can accept three-prong plugs. The max AC output is 1200W of Pure Sine Wave, and unlike the 70mai Hiker 400 power station that I reviewed, this one does have a 1200W hard limit.

 

I was easily able to power my Lasko heater on its low setting, and that was pulling about 750W; however, once I set my heater to its higher setting, which pulled about 1350W, the power station was able to power the heater for about 30 seconds, and then it automatically shut down.

The one other appliance I tested was an electric cooktop that was rated to use 1000W, but it usually pulls about 850W, as it did with the Tera 1000 power station. So the 1200W max output across three AC outlets is very good, and you’re going to be able to power a decent number of appliances simultaneously, but you have to ensure you’re within that 1200W range.

Recharging

Recharging for the Tera 1000 power station can be done in three ways: using the included AC charging cable, car charging cable, or solar panel. The fastest way to recharge this power station is to use the AC charging cable because you can AC recharge the power station anywhere from 250W to 750W.

You can change the AC recharge rate from 250W to 750W on the power station directly or via the app. You may want to use the slower AC recharge option because it’s easier on the batteries, but 750W for recharging a 1043Wh capacity is what I find to be better.

Also, just a heads up, this Tera 1000 power station does not feature AC pass-through charging, so you cannot use the AC outlets when you’re AC recharging the power station. You can use the AC outlets when using a car or solar recharging.

The car charging cable can recharge the power station at 100W, so it’s one of the slower options for recharging, but it’s still an option. The DC 7909 port at the front is used for car charging.

For solar recharging, you have to use the Anderson input port at the front of the power station, and solar recharging maxes out at 200W. I used a 70mai 110W solar panel to test out solar recharging and got nearly 100W on a clear sky day which is very good. You could also put two 100W solar panels in series or use a 200W solar panel for faster solar recharging.

Design

Since the power station does have a decent capacity and output, the size and weight are expected. The charger has a length of 11 inches, a width of 8 inches, and a height of 11 inches. The weight of the power station is 27 pounds. So the size isn’t too large, but the weight is something you’re going to notice, but thankfully there is a large bright orange handle at the top.

At the front is where you’ll spend most of your time, as that’s where you can find nearly all the ports; however, the AC input is at the back.

You do have to hold the power button for the power station down to turn it on, and then the screen in the middle turns on, showing the remaining capacity.

You can do quite a few things from the screen, such as changing the AC recharging speed, voltage, and frequency output of the AC outlets, and Auto shutting off the DC and AC sections can also be controlled from the screen.

The biggest downside design-wise for the Tera 1000 power station is the flashlight because it’s not a flashlight. It’s just an illumination light that is very dim and has a SOS mode.

Conclusion

The 70mai Tera 1000 power station is a powerful one that has enough capacity and power output to fit most needs. The unit’s design is done well and includes the fast AC recharging, the screen, and the app compatibility. It has a few faults, such as the flashlight, not using LiFePO4 batteries, and the power station does not have a solar charging cable. However, overall, I would recommend it for the right price.
