I really like this power bank. I decided to put it through its paces and not go easy on the power bank. I’d say the capacity is adequate. I am reviewing this after about half a year and 50 cycles (a cycle is a full charge to 100 per cent – for example, charging from 50 per cent to 100 per cent twice, not every partial charge). The power bank shows 98% of its original 100% capacity and 1,831 Wh of energy output. As I’m a bit of a gadget enthusiast, I really enjoy the display – you can tell someone’s put a lot of effort into it. I think it’s a nice touch that the colour changes depending on whether the battery is charging or discharging, and that it increases in increments of tenths of a per cent whilst charging. Current power consumption in W (accuracy plus or minus 1 W, so that’s fine). However, the remaining time must be taken with a pinch of salt, especially when the capacity is low – I’ve rarely managed to get it below 20 per cent (at least 17 per cent); after that, it switches off and, when switched on again, it already shows 0 per cent. I realise that this is a small power bank with limited capabilities, but I’ll mention its limitations all the same. It probably has a single chip, so it’s either charging or discharging, and there’s only one PD charging port; the other outputs are 5V only. The clock seemed like a good idea to me – I wouldn’t mind leaving it on a table somewhere when I don’t need to charge anything – but it switches off after 30 minutes and, what’s more, after about half a year it was running nearly an hour slow. Another thing is the ‘30W’ – at this setting, it charges for about 10 minutes, then it heats up and switches to 15W, which isn’t bad, but it’s worth noting. It’s great that it was one of the few that could be charged using an Action solar panel (four fold-out panels), and even though it heated up to 50 degrees, it managed to charge from 0 to 100 per cent in about four hours on a sunny day. (Other power banks had issues and charged at a maximum of 5W); this one charges at 10–15W. Perhaps someone will appreciate this during the holiday season. Overall, though, I can only recommend it. I carry it in my handbag; it charges my mobile about 1.5 times at most, but that’s in line with its capacity. I’m happy with it, and although I’ve got several power banks, I’ve grown particularly fond of this one – its design, the display, the shape and the features. Overall super
