Web3 Pi UPS
The newest member of the Web3 Pi ecosystem, built to ensure perfect reliability of your Ethereum node around the clock. Essential for Solo Staking, it shields your setup from any power disruption — no matter how brief. When the power goes out, your node stays up — and when the battery runs low, it shuts down safely.
Main Features
Designed specifically for Raspberry Pi 5 and USB-C PD devices
Native Raspberry Pi 5 Power Support
Provides 5.1V 5A continuous output, fully compatible with Raspberry Pi 5 power requirements. No undervoltage warnings, no compatibility messages, no PD timing issues.
USB-C Power + Data over Single Cable
Power delivery and communication share the same USB-C connection. The UPS exposes a serial interface to the OS, enabling telemetry, event detection, and graceful shutdown.
Full USB-C Power Delivery (IN & OUT)
USB-C PD input: 12V to 20V, 27W+. USB-C PD output: 5V / 9V / 12V / 15V / 20V. Automatic profile negotiation - when Raspberry Pi 5 is detected, selects 5.1V 5A automatically.
Three Power Sources with Seamless Switching
USB-C PD input, DC barrel jack (12-24V), and Sony NP-F series battery. Maintains output power as long as any single source is available.
Battery System
Uses Sony NP-F series Li-Ion batteries - widely available photographic batteries used worldwide.
User-Replaceable
Standard photographic batteries available worldwide - no proprietary cells.
Hot-Swappable
Replace batteries without powering down when external power is connected.
Multiple Capacities
NP-F570 (~2.5h), NP-F770 (~5h), or NP-F970 (~10h runtime).
Power Path Management & Battery Care
Active Power Path Management
When external power is present and battery is fully charged, the battery is bypassed - reducing wear and extending lifespan.
Instant Failover
Interruption-free switching when external power is lost. Your system never sees a power drop.
True DC UPS
Not an AC inverter-based solution. No 230V to 5V conversion means higher efficiency and smaller size.
Display & System Integration
Full visibility and control without external hardware
Integrated display shows battery charge, input/output voltage, and power state (charging, discharging, fully charged, no battery, error). Built-in buzzer provides audible alerts for critical events.
Device is detected as a USB serial interface. Companion system service reads telemetry and power events in JSON format, making integration trivial.
Enables graceful shutdown on low battery, automatic restart after power return, logging of power events, and integration with monitoring stacks.
Designed for Any Setup
Works with Any Enclosure
Does not use GPIO and does not require physical stacking. Works with any Raspberry Pi 5 enclosure, orientation-independent.
Compact & Silent
Similar in size to Raspberry Pi 5. Completely silent - no fans, passive cooling only.
Open Hardware & Software
Open hardware design, open firmware and system software, transparent communication protocol. Audit it, extend it, integrate it however you want.
Built for 24/7 Operation
Web3 Pi UPS was created as a core component of the Web3 Pi ecosystem.
In Ethereum solo staking and other always-on workloads, even short power outages can result in real financial losses. This UPS protects your node by:
- Maintaining power during outages
- Allowing the OS to shut down cleanly
- Preventing database corruption
- Enabling fast, safe recovery
It also protects against unstable grids, brief power drops, and accidental cable disconnections.
