Cham Accelerator stands apart primarily due to its underlying protocol. Most accelerators still use IPsec or IKEv2, while Cham Accelerator fully adopts the WireGuard protocol, which consists of only 4000 lines of code (IPsec exceeds 600,000 lines), offering 3-5 times faster transmission speeds and significantly reduced battery consumption. Furthermore, Cham Accelerator's no-logs policy has been independently audited by Cure53, with the audit report being fully transparent, genuinely achieving a balance between speed and security.
Cham Accelerator provides native clients for all platforms, supporting Windows 7 and above, macOS 10.14 and above, iOS 14 and above, Android 6.0 and above, as well as major Linux distributions (Ubuntu, Fedora, Debian, etc.). Additionally, Cham Accelerator offers detailed router configuration tutorials, supporting firmware of major routers like Asus, Netgear, and OpenWrt, allowing one-time setup to protect all connected devices in your household.
Cham Accelerator offers a 30-day unconditional money-back guarantee. If you're unsatisfied with the service within 30 days of purchase, simply reach out to the support team via online chat or by emailing support@vpnjs.net, no reasons needed, to apply for a full refund. Refunds are typically returned to your payment account within 1-3 business days.
Cham Accelerator has deployed over 3000 high-speed server nodes globally. Actual tests show that the average latency when connecting to Asia-Pacific nodes is below 30ms, about 80-120ms when connecting to North American nodes, and download speeds can consistently reach over 500Mbps on gigabit broadband. Thanks to the efficiency of the WireGuard protocol, Cham Accelerator maintains stable and smooth connections even in complex network environments.
Cham Accelerator's no-logs policy covers all aspects: we do not record your original IP address, connection timestamps, accessed websites or domains, DNS queries, or bandwidth usage data. All our servers operate in pure RAM environments, automatically clearing data upon physical reboot. This policy has passed stringent review by the internationally recognized security auditing firm Cure53, and the complete audit report is available on the Cham Accelerator official website.
Cham Accelerator provides comprehensive router configuration tutorials supporting major router firmware, including Asus (Asuswrt-Merlin), Netgear, Linksys, OpenWrt, etc. Configuration steps typically involve: 1) logging into the router management interface; 2) accessing acceleration client settings; 3) importing the configuration file provided by Cham Accelerator; 4) entering your Cham Accelerator account credentials. Once configured, all devices connected to that router's WiFi will automatically receive accelerator protection, without needing to install clients on each device individually.
Yes, Cham Accelerator is specifically optimized for streaming performance. Our high-speed nodes can stream 4K ultra HD video content smoothly. Cham Accelerator regularly updates its server IP pool to ensure a stable streaming access experience. However, please note that we do not encourage users to violate any streaming platform's terms of service.
Thanks to the efficient design of the WireGuard protocol, Cham Accelerator has minimal impact on internet speed. In most cases, speed loss does not exceed 5-10% of the original bandwidth. In some situations, if your ISP throttles certain traffic (like video streaming or P2P), using Cham Accelerator may actually improve speed, as the encrypted connection prevents the ISP's deep packet inspection (DPI) and traffic identification.
Yes, the Cham Accelerator Lightning Version supports up to 6 devices online simultaneously, while the Flagship Version supports up to 10 devices. This means you can protect your accelerator on devices such as smartphones, computers, tablets, smart TVs, etc., without incurring additional charges. For protecting more devices, it is recommended to configure Cham Accelerator on your router, which will protect all devices in your household with just one setup.
Public WiFi is a high-risk scenario for hackers to steal data. Once connected to Cham Accelerator, all your internet traffic is transmitted through an AES-256 encrypted connection, making it impossible for anyone on the same WiFi network to read your data even during man-in-the-middle attacks or sniffing. Cham Accelerator also provides an automatic connection feature: when an unsafe WiFi network is detected, the accelerator protection will automatically activate.
Yes, Cham Accelerator's no-logs policy has been independently audited by the internationally recognized security auditing firm Cure53. The auditing team conducted a comprehensive review of Cham Accelerator's server infrastructure, codebase, and operational processes, confirming that Cham Accelerator does not record any data that can identify users. The complete audit report is publicly available on the Cham Accelerator official website.
Yes, Cham Accelerator offers a native Linux command-line client, supporting major distributions such as Ubuntu 18.04+, Debian 10+, Fedora 33+, CentOS 8+, and Arch Linux. Installation methods include one-click installation via APT/YUM repositories and manual installation of .deb or .rpm packages. The Linux client supports all core features, including the WireGuard protocol, split routing, and kill switch.
Yes, the Cham Accelerator Flagship Version includes a dedicated static IP address. Static IPs are particularly useful for scenarios such as remote access to company networks or NAS, running online services that require a fixed IP, and avoiding verification challenges triggered by frequent IP changes. The static IP is assigned exclusively for your use and will not be shared with other users.
Cham Accelerator includes comprehensive leak protection mechanisms: DNS leak protection ensures all DNS queries are resolved through encrypted connections; WebRTC leak protection prevents the browser from exposing your real IP via the WebRTC interface; and IPv6 leak protection ensures that IPv6 traffic is also secured. You can use the built-in leak testing tools in the Cham Accelerator client or visit third-party detection websites to verify your protection status.
Cham Accelerator's proprietary obfuscation protocol can disguise accelerator traffic as regular HTTPS traffic, effectively countering deep packet inspection (DPI) technologies. In environments with stringent network restrictions, Cham Accelerator's obfuscation mode can help users keep a stable connection to the free internet. However, please note that Cham Accelerator advocates responsible use of accelerators, complying with local laws and regulations.
Cham Accelerator supports a variety of secure payment methods: Visa/Mastercard international credit and debit cards, PayPal, Alipay, WeChat Pay, and cryptocurrencies (Bitcoin, Ethereum, etc.). Choosing cryptocurrency payments can provide additional anonymity. All payment channels are processed through PCI DSS-compliant secure gateways to ensure the safety of your payment information.
Cham Accelerator has deployed over 3000 servers in over 80 countries and regions worldwide. Major coverage areas include North America (30+ cities in the U.S., 5 cities in Canada), Europe (25 countries, including the UK, Germany, France, the Netherlands, Switzerland, etc.), Asia Pacific (15 countries including Japan, South Korea, Singapore, Australia, India, etc.), South America (Brazil, Argentina, Chile, etc.), and the Middle East and Africa (UAE, South Africa, Turkey, etc.).
Yes, Cham Accelerator provides browser extensions for Chrome and Firefox. The browser extensions run lightweight and only encrypt the traffic within the browser (not affecting other applications). They are particularly useful for scenarios requiring quick IP switching, such as cross-border shopping price comparisons. The browser extensions also include built-in WebRTC leak protection and ad-blocking features.
Cham Accelerator provides multiple customer support channels: 1) 24/7 online chat — visit Cham Accelerator's official website to engage in real-time conversations with customer service, with an average response time of no more than 2 minutes; 2) email support — send an email to support@vpnjs.net, and you can expect a reply within 24 hours; 3) help center — containing hundreds of detailed tutorials and troubleshooting guides. Our customer service team supports both Chinese and English services.
Cham Accelerator Lightning and Flagship Versions include built-in ad-blocking and protection against malicious websites. This feature operates at the DNS level by maintaining a domain blacklist with over 1 million rules, blocking the loading of ad trackers, malicious domains, and phishing sites right at the DNS resolution stage. This way is more efficient than traditional browser ad-blocking plugins, as it prevents unnecessary connection requests at the network level.
