For handheld builds, try TP4056 charger + MT3608 booster (our lab tests show 2.5A handles CM4 at full load). Key tip: use Li-ion protection boards with balancing - we fried a Pi using standard boards before. The official doc section 4.2 has power circuit details, I can share our improved schematic if needed. ![:D]( "Very Happy")
