Adafruit Introduces Versatile PowerBoost 1000C for Portable Electronics
New York, Sunday, 23 March 2025.
Adafruit’s PowerBoost 1000C offers constant power from a 3.7V battery while recharging, vital for DIY projects needing uninterrupted power.
Technical Specifications and Performance
The PowerBoost 1000C utilizes Texas Instruments’ TPS61090 boost converter chip, delivering a consistent 5.2V DC output from a 3.7V LiIon/LiPoly battery input. The device features sophisticated capabilities including low battery detection, a 2A internal switch, and high-efficiency synchronous conversion operating at 700KHz [1]. A notable feature is its smart load-sharing LiPoly charger, capable of delivering up to 1000mA charging current while simultaneously maintaining boost operation [1].
Real-World Applications and Integration
The PowerBoost 1000C has already demonstrated its versatility in practical applications. Recent implementations include the SwitchBerry gaming project, where it powers a Raspberry Pi-based portable gaming system using a 3.7V 4400mAh LiPo battery configuration [8]. The device has proven particularly valuable for compact cyberdeck projects, as evidenced by recent Raspberry Pi conversions requiring reliable portable power solutions [4].
Power Management and Reliability
For optimal performance, the PowerBoost 1000C requires specific power management considerations. The integrated MCP73871 chip manages load spikes up to 1.8A, necessitating a constant LiPo battery connection [1]. The system automatically switches to USB power when available, functioning effectively as an uninterruptible power supply. For reliable operation, users should employ a high-quality 2A USB adapter with robust power wires to ensure optimal charging performance [1].
European Market Compliance
The PowerBoost 1000C meets European regulatory standards, holding both RoHS 2 2011/65/EU and RoHS 2 2015/863/EU compliance certifications [1]. This compliance ensures its availability and legal use across European markets, making it a viable option for both hobbyist and professional applications within the EU [GPT].
