Cham Accelerator fully utilizes the WireGuard protocol, with code volume just 1/100 of IPsec, yet delivering 3-5 times faster transmission speeds. Its streamlined code means a smaller attack surface and enhanced security, allowing you to enjoy ultra-fast speeds without worrying about privacy breaches.
Cham Accelerator enforces the industry's most stringent no-logs policy — we do not record your connection times, accessed websites, IP addresses, or any browsing data. This policy has been independently audited by the internationally recognized security organization Cure53, with the complete report made public, ensuring that every commitment can withstand scrutiny.
Cham Accelerator's intelligent routing engine monitors global node latency and load in real-time, automatically matching you with the best route. One-click connections have latencies as low as 15ms, providing a smooth experience whether for video conferences, online gaming, or 4K streaming.
Cham Accelerator has deployed over 3000 high-speed servers in more than 80 countries and regions, including North America, Europe, Asia Pacific, South America, and the Middle East. Each server runs in pure RAM mode, clearing all data upon reboot, eliminating any possibility of data retention at the hardware level.
With one Cham Accelerator account, you can protect your smartphone, computer, tablet, smart TV, and router simultaneously — up to 6 devices connected at the same time, allowing your family to share a secure network without extra charges. After configuring the router, you can even protect IoT devices that do not support accelerator.
Cham Accelerator has a bilingual professional customer service team available 24/7. Whether for installation, connectivity issues, or account management, you can get immediate, professional assistance via online chat or email, with an average response time of less than 2 minutes.
Learn how the cutting-edge routing protocols employed by Cham Accelerator provide you with unparalleled speed and security
Cham Accelerator built a new routing engine based on the WireGuard protocol. WireGuard achieves full accelerator functionality with only about 4000 lines of code, while traditional IPsec requires over 600,000 lines. This streamlined code results in a smaller attack surface, lower latency, and higher throughput. In our internal tests, the handshake speed of the WireGuard protocol is three times faster than IKEv2 and eight times faster than IPsec.
Cham Accelerator's implementation of WireGuard utilizes the Noise protocol framework for key exchange, employing Curve25519 for ECDH key negotiation, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing operations. This combination of cryptographic primitives has been widely validated by both academia and industry, offering prospective security guarantees against quantum computing attacks.
In certain network environments, WireGuard's UDP traffic may be restricted. Cham Accelerator features built-in smart protocol switching that automatically detects network conditions and seamlessly switches between WireGuard, IKEv2, and our proprietary obfuscation protocol, ensuring a stable connection in any environment. The entire switching process is completed within 500 milliseconds, undetectable to users.
Multi-layer encryption technologies and a strict privacy policy comprehensively protect your digital life
Cham Accelerator uses the AES-256-GCM encryption mode to secure all transmitted data. AES-256 is the encryption standard currently approved by the NSA for protecting 'Top Secret' information. Even the most powerful supercomputers would take billions of years to crack it. Each connection generates a unique session key, ensuring forward secrecy.
Cham Accelerator operates its own private DNS server cluster, with all DNS queries resolved through encrypted connections, eliminating the risk of DNS leaks. We also offer built-in WebRTC and IPv6 leak protection to ensure your real IP address is never exposed under any circumstances. You can verify your protection status anytime using our built-in leak testing tools.
Cham Accelerator's kill switch feature can instantly cut off all internet traffic if the acceleration connection unexpectedly drops, preventing any data from leaking unencrypted. This feature supports both system-level and app-level operations: system-level mode protects all traffic, while app-level mode only protects specified applications, providing users with maximum flexibility.
High-speed connections optimized for streaming and online entertainment, allowing you to enjoy exciting global content
Cham Accelerator's high-speed nodes are specifically optimized to reliably support the transmission requirements for 4K Ultra HD (2160p) video streams. Whether it's HD movies, live sports events, or music videos, Cham Accelerator provides a stable, smooth, and buffer-free viewing experience. On gigabit broadband, connection speeds can reliably maintain over 500Mbps.
Cham Accelerator has been specially optimized for online gaming. Our intelligent routing engine automatically selects the route with the lowest latency to gaming servers. In our tests, the latency connecting to Asia-Pacific gaming servers is as low as 10ms, and to North American servers, as low as 60ms. DDoS protection features prevent you from suffering from malicious attacks during gaming.
Cham Accelerator has enabled P2P optimization features on nodes in over 30 countries worldwide. We do not limit the bandwidth or speed of P2P protocols like BitTorrent, while protecting your downloading activities from ISP monitoring and throttling through encrypted connections. The port forwarding feature enhances seeding efficiency, enabling faster upload speeds.
