What happened
YouTuber Gadget Industry designed a one-hand-sized portable power station that delivers more than 500W of total output and can run a full desktop PC. S1 The build pairs a 300W AC inverter with 140W and 65W USB-C ports for phones, laptops, and other gadgets. S1
Energy storage is built from four 3.2V, 15Ah LiFePO4 cells wired in series to form a 12.8V pack that rises to 14.6V at full charge. S1 The cells carry a 3C rating, allowing up to 45A discharge, and a 100A BMS handles per-cell voltage monitoring, balancing, overcurrent, and short-circuit protection. S1
To shrink the inverter, Gadget Industry disassembled an off-the-shelf 300W module, cut the PCB in half, and bridged the severed traces with jumper wires. S1 Large capacitors were laid sideways between the cylindrical cells, the transformer was relocated across the pack, and the MOSFETs were moved to an aluminum heat sink. S1 A 55 °C thermal switch activates a cooling fan only when needed. S1
The 140W and 65W USB-C boards had their connectors desoldered and extended so the modules could sit flat inside the case. S1 The 140W port is bidirectional and serves as the main charging input; a separate boost converter and voltage regulator allow slow recharging from a standard 5V phone charger when USB-PD is not available. S1 The electronics are potted in a dark green epoxy enclosure with a matching lid. S1 During testing, the unit powered a desktop PC from the AC outlet while simultaneously fast-charging two smartphones. S1

XAIPART take
Technical impact
The 3C cell rating and 100A BMS leave substantial headroom over the 300W inverter draw, which improves thermal margin but also signals the pack could be pushed harder if a higher-power inverter were re-integrated. Splitting the inverter PCB and relocating the transformer and MOSFETs to a shared aluminum heat sink is a classic high-density power layout and explains how 300W of conversion fits next to four cylindrical cells. XAIPART analysis
Market impact
For buyers sourcing LiFePO4 cells, USB-PD modules, and sub-300W inverters, this build is a useful reference for what hobbyists are achieving with off-the-shelf parts, and it may nudge demand toward compact 100A BMS units paired with 15Ah 3C cells. Distribution of genuine, graded 3C LiFePO4 cells in 15Ah form factors will influence whether similar projects scale. XAIPART analysis
Action
Engineers prototyping portable power can reuse the documented topology: four-series 3.2V 15Ah LiFePO4 cells, a 100A BMS, a thermally-managed sub-300W inverter, and bidirectional 140W USB-PD for charge/discharge. Procurement teams should confirm cell authenticity and matching internal resistance before paralleling packs, since the source does not disclose cycle life or capacity verification procedures.

XAIPART Forecast
XAIPART expects that, by Q2 2027, at least two hobbyist-grade LiFePO4 power stations using a four-series 15Ah cell stack with a 100A BMS will be documented as reaching sustained 300W AC output in a sub-1kg enclosure; if no such project is published by 2027-06-30 with verified thermal data, this forecast is wrong.

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. Uncertainty: pack energy in Wh, full-load runtime, weight, and cycle life are not disclosed by the source; the build is a single hobbyist project and has not been independently safety-certified.
