The Charge Preserve Evidence Bag is the first evidence bag to integrate a USB charging cable directly into the bag — allowing seized devices to stay powered without ever breaking the hermetic seal. Designed for law enforcement and digital forensic teams, it preserves both physical evidence (DNA, fingerprints, blood) and digital data simultaneously. Made from tamper-evident PET+PE with UL-certified cables, this patent-pending design is purpose-built to meet forensic chain of custody standards from the moment of seizure to lab analysis.
Standard evidence bags force a choice: pierce the bag to charge the device or leave it unpowered and risk lockout mode. The Charge Preserve Evidence Bag eliminates that tradeoff entirely.
A streamlined process that keeps evidence secure and the device live at every stage.

Every cable is lab-tested and UL-certified. Choose the tip that matches your casework, or order the variety pack to cover all bases.
- USB-C — Modern Android, iOS 15+, and most current devices
- USB Lightning — iPhone and iPad with Lightning connector
- USB Micro — Older Android and legacy devices
- USB Variety — Mixed combination for diverse caseloads

Ships with a protective binder for field deployment. Departments can insert their own procedural instructions and accessories.
- 10x Charge Preserve Evidence Bags (choice of cable tip)
- 2x USB extension cables
- Evidence bag holder binder with printed usage instructions

Pair with the Charge & Shield Faraday Bag for RF isolation. The dual-sided USB filter is fully compatible with the evidence bag's cable tip.
- Prevents hacking, tracking, remote wiping, and data corruption
- Window lets you view device state and notes through the evidence bag
- Keeps the faraday bag clean from biological contaminants
When a device is seized, it often carries more than just digital data — biological evidence like DNA, fingerprints, and blood may be present on the surface. The Charge Preserve Evidence Bag's hermetic seal protects all of it simultaneously.
Hermetically seals the device and any biological matter on its surface — DNA, fingerprints, blood, hair — from the moment of seizure. Transparent for full visibility. Tamper-evident once sealed.
Pairs with the evidence bag to collect and preserve physical DNA found on the device. Includes forensic gloves, sterile gauze pads, DNA swabs, desiccant packets, tamper-evident DNA envelopes, and port cleaning swabs.
Forensic teams no longer have to choose between preserving digital data or collecting physical DNA evidence — the Charge Preserve solution ensures both are secured from the moment of seizure, streamlining the process and strengthening the integrity of the entire investigation.
The Charge Preserve Evidence Bag is designed for law enforcement and digital forensic teams who need a reliable, court-admissible method for seizing and transporting electronic devices without compromising evidence integrity.
Secure and transport seized devices while preserving both digital content and biological evidence for prosecution.
Maintain device power during incident response to prevent data loss and enable faster forensic extraction.
Tamper-evident seals, printed chain of custody fields, and hermetic integrity support evidence admissibility in court.
Keep devices live from seizure to lab — reducing time to extraction and minimizing passcode lockout risk.
Compact and ready to deploy. Officers can seal and power a device in seconds without specialized equipment.
Available in bulk packs with instruction cards for consistent protocol deployment across departments.

Forensic Tool Integration
Keeping the device live and powered enables faster data extraction and passcode unlocking with tools like GrayKey, Cellebrite, XRY, BlackBag, and Oxygen Forensics.
Follow these steps for proper evidence handling. Full instructions are also printed on the front of each bag.
Important Note
Do not pierce or modify the bag to route a cable — this destroys the hermetic seal and may compromise evidence admissibility.
