Product details
Made possible by exploring innovative molded plywood techniques, Iskos-Berlin’s Soft Edge Chair blends strong curves with extreme lightness to create a three-dimensionality not usually possible with 2-D plywood.
Description
TP4056 with Integrated Step‑Up Boost Converter is a board that mixes a full single‑cell 3.7V lithium‑ion charger with a DC‑DC boost regulator. TP4056 removes the need for charging and boosting boards letting me charge an 18650 or Li‑Po battery at once with a Micro‑USB or Type‑C cable and step the battery voltage up to a steady 4.3V, to 27V DC output using an onboard multi‑turn trimpot.

Key Features
- All-in-One Power Solution: This product brings together battery charging, discharging path and DC-DC step-up circuitry in one board.
- Adjustable Boost Range: A multi-turn trimmer makes it easy to adjust the output smoothly from 4.3V up to 27V DC (perfect, for 5V, 9V or 12V projects).
- Simultaneous Charge & Discharge: It can power loads while also charging the battery that is connected.
- Onboard LED Indicators: Two separate LEDs show the charging and charged status (Red means charging Blue or Green means fully charged).
