We’ll start with its surprising size 
and yes it weighs 3.6 kg a very appreciable weight since we can slip it into our 22L backpack 
It is therefore the smallest battery from BLUETTI with a power of 300w and can go up to 600W in elevation mode. It has a capacity of 204WH and also a UPS function.
It has a fairly bright screen.
It can be recharged using a solar panel, the pv200 is ideal
On the mains, it also offers 3 charging modes:
In Standard mode it recharges in 1h47 min In Turbo mode, it charges in 1h07min In silent mode it recharges in 4h03 min
Also possible with car charger
It’s quite quiet 41 dB
On the ac2a there have been some modifications like the handle, but it is not unpleasant at all, quite the contrary, perhaps because of its weight which is quite light.
You can take it with one hand with great ease.
There is no more wireless charging, which we regret a little, it is so easy to move, that being able to charge your phone so easily would not have been unpleasant.
To conclude, we love it We use it daily, whether at home or on the go. It is super light, ideal to carry in a backpack. We use it to charge our phones, tablets, watches, LED lights and computers.
It’s a small battery, for example for a 100% charge we will recharge 1 computer which will take (50%) and 3 times the cell phone.
So if you are looking for a small battery to work quietly on your computer outdoors, it is perfect. It recharges quickly and is efficient.
