PopSocket PopPower 2 is to be the world's first wireless charger with the latest NuCurrent Qi design spec
NuCurrent is a company that aims to stay at the forefront of the wireless (and, potentially, contactless) charging space through the release of specifications intended to result in generational refinements in the form and function of the internal technology involved.
This might help OEMs make devices that could be sleeker, slimmer, or (potentially more importantly) more distinctive, such as the PopPower charger with the custom-made divot necessary to conform to PopSockets - which seem to have become as ubiquitous and unavoidable as smartphones themselves to the extent that they now come in MagSafe-compatible variants.
The first-gen, first-party wireless charger is designed according to the MP-A17 Qi design spec that allows it to deliver 15W through up to 12mm of interceding material (cases and grips included), or up to 3x the distance of the preceding NuCurrent standard.
They have both been superceded by MP-A24, however, which has the same wireless charging specs, but shrinks the size of the internal components needed to deliver them by up to 82%. Accordingly, NuCurrent and PopSockets back the PopPower 2 to have a "slimmer" form-factor than its predecessor on its launch.
