SBCs are great. Reading through our extensive list of SBC reviews we’ve created over the past few years, one can notice our own love for these little systems enabling everyone to deploy IoT systems and create various server-based projects, among other things. At the same time, certain models have proved themselves worthy of serious industrial use thanks to their wide IO arrays and reliability. SBCs also draw impressively little power, with the most power-hungry models rarely requiring more than 15W under top loads, making them very easy to power.
Sadly, that power is usually provided by a switched-mode power brick attached to a nearby outlet and delivered through a USB port – which means that there’s nothing between a power outage and your data being lost or services being fully interrupted. Short of a full-size desktop UPS, there’s not much that can be done to combat outages – but given the fact that compact size is one of the biggest upsides of an SBC, it’s easy to see why a large, bulky battery backup box is somewhat inappropriate in most use-cases.
In today’s review we’re taking a look at a solution to this problem – SunFounder’s PiPower – a tiny, easily attached and sleek UPS system designed for SBCs. While it’s not the first device of its kind, it’s certainly the neatest one we’ve seen so far. SunFounder sent this device free of charge to us for review purposes.
Inside the box are quite a few parts – all the screws and standoffs, an acrylic backing plate, a screwdriver and the PiPower module itself. Two high-quality braided cables (one Type-C and one Micro USB) for connecting the UPS to the SBC are also included in the set – which is a great touch. These cables are extra-short, which is great for keeping the setup tidy (can you even easily get such tiny cables commercially?) and for keeping the overall footprint small.
