There are plenty of reasons why you would want to carry with you an energy source beyond just mere power banks. Not only do they hold more power than even the highest capacity power bank, but they also provide greater output for more intensive use. It is for this reason that portable generators have been in the rage in recent years, which inevitably puts veteran companies like BLUETTI in the spotlight for their high-quality products.
In continuation of that reputation, BLUETTI is introducing not just one, but two new portable generators that could make your outdoor adventure more comfortable than it otherwise would have been. Meet the BLUETTI AC2A and BLUETTI AC70.
The smaller between the duo, the BLUETTI AC2A banks on portability while not compromising on its ability to provide needed energy on the go. Light enough to carry in your backpack, this portable generator weighs only 7.9 lbs (3.6 kg). Yet, despite its tinier stature, the AC2A is capable of outputting 300W of pure AC energy and can surge to up to 600W.

With a 204Wh capacity, the AC2A features six different ports, two of which serve as 120V (5A) AC outlets. The rest of the ports comprise two USB-A ports, a high-speed 100W USB-C port, and a 12V DC outlet.
At the rate of 270W for input from a wall outlet, the BLUETTI AC2A can be charged to full battery in just 1.4 hours. But if you are looking to get energy from a renewable source, the portable generator has a 200W solar charging station, which only takes 1.5 of complete charging.
At 7.5W of no-load loss, it marks as BLUETTI’s lowest yet, making the AC2A very energy-efficient. But while the AC2A’s specification is itself amazing, the BLUETTI AC70 takes things up notches as the superior of the two offerings. With a 768Wh capacity, it is almost four times bigger than its smaller sibling.

Its power output is also significantly greater, too, at 1000W with a chance to surge to up to twice that at 2000W.Although it shares a similar number of ports as the AC2A, the AC70 has the more powerful 120V outlets at 8.33A.
A massive battery capacity will surely take a lot of time to recharge. But the AC70 defies expectations by offering a similar charging duration of 1.5 hours as the AC2A, due to its higher power draw of 850W AC. Resorting to solar charging at 500W, meanwhile, takes 2 hours to complete charge.
Both the AC2A and AC70 share the same LiFePO4 batteries, which are capable of up to 3,000 charge cycles. Price-wise, the AC2A costs $179 while the AC70 costs $499.
