It's worth buying this product only if the most important criterion (in addition to the favorable price) is that it is easily portable. Naturally, proportionate capacity is associated with the small mass. (8Ah) It's worth weighing this before purchasing. I recommend it primarily for charging laptops and phones, for example, a laptop with a consumption of 40-60 W can last 2-3 hours on it while traveling. In addition, I use it for measuring the momentary consumption of laboratory purposes and small consumers. Based on my experience of 2-3 days, it can supply power to a modem and router for a relatively long period of continuous use at 5W constant consumption, providing 30 hours of operation time via DC.
Tiny but powerful powerstation. Didnt try the max capacity, but it is putting out pure sine-wave. Display is good, but slightly less visible in direct sunlight. It is good that the Mains inverter is in the device, so you only need the cable, no power brick, but Id prefer to have the mains connector would be the regular power line same as for a monitor or pc. Perhaps Ill change it later on to be a bit more compatible.
