Digital Camera World Verdict

Who knew I wanted a screen in a power bank so much? What I thought was just going to be a gimmick is actually an incredibly useful feature that does innovate what is essentially otherwise just a big battery. The power percentage and countdown timer for charging/discharging the battery is the most accurate way I have yet seen for monitoring a power bank. Yes, knowing exactly what speed my devices are charging at is not essential, but it is really interesting to know, and also seeing just how fast or slow some things can charge has affected how I think about charging them. It’s not just the screen that makes this Anker Prime power bank a hit, it also has an ample 20,000mAh of battery and a huge 200W maximum output. I have several power banks, but this Anker Prime has become my new go-to.

Power banks have been around for the better part of the last decade now, and have proven to be the most useful way to top up your devices with power while on the go. Over time power banks have incrementally evolved at a steady pace, increasing their capacities, getting smaller, and offering more powerful ports with faster charging speeds. It is rare that something comes along that actually might make you think differently about what otherwise, is not the most interesting device.

Other power banks have featured a digital display, usually in the style of an old-school digital clock radio counting down the percentage left in the battery, however, Anker has taken that a step further, and added a full readout display to its latest Anker Prime power banks that offer you far more information than just a simple battery percentage. However, I can get plenty of cheaper power banks without a display, so do I really need a full readout on what is just a big battery I plug my phone into while I am out?
