FAQ

Xiaoheiniu Accelerator provides detailed router configuration tutorials, supporting major router firmware like Asus (Asuswrt-Merlin), Netgear, Linksys, and OpenWrt. Typical configuration steps include: 1) logging into the router management interface; 2) accessing acceleration client settings; 3) importing the configuration file provided by Xiaoheiniu Accelerator; 4) entering your Xiaoheiniu Accelerator account credentials. Once configured, all devices connected to that router's WiFi will automatically achieve accelerator protection without needing individual installations on each device.

Yes, Xiaoheiniu Accelerator is specifically optimized for streaming performance. Our high-speed nodes can smoothly stream 4K ultra-high-definition video content. Xiaoheiniu Accelerator regularly updates its server IP pool to ensure a stable streaming access experience. However, please note that Xiaoheiniu Accelerator does not encourage users to violate the terms of service of any streaming platform.

Thanks to the efficient design of the WireGuard protocol, Xiaoheiniu Accelerator has minimal impact on internet speeds. In most cases, speed loss does not exceed 5-10% of the original bandwidth. In some cases, if your ISP throttles specific traffic (like video streaming or P2P), using Xiaoheiniu Accelerator may actually improve your speed, as the encrypted connection prevents the ISP from conducting deep packet inspection (DPI) and traffic identification.

Yes, the Lightning version supports up to 6 simultaneous devices, while the Flagship version supports up to 10 devices. This means you can use accelerator protection simultaneously on your phone, computer, tablet, smart TV, and more, without extra costs. For protecting more devices, we recommend configuring Xiaoheiniu Accelerator on your router to secure all devices in the household with a single setup.

Public WiFi networks are high-risk environments for data theft by hackers. When connected to Xiaoheiniu Accelerator, all your internet traffic is encrypted through an AES-256 connection, preventing any data from being read even if someone on the same WiFi network conducts man-in-the-middle attacks or sniffing. Xiaoheiniu Accelerator also features an automatic connect function that activates accelerator protection when an insecure WiFi network is detected.

Yes, Xiaoheiniu Accelerator's no-logs policy has been independently audited by the internationally recognized security audit firm Cure53. The audit team conducted a comprehensive review of Xiaoheiniu Accelerator's server infrastructure, codebase, and operational processes, confirming that Xiaoheiniu Accelerator does not record any identifiable user data. The full audit report is publicly accessible on Xiaoheiniu Accelerator's official website.

Yes, Xiaoheiniu Accelerator offers a native Linux command-line client, supporting mainstream distributions like Ubuntu 18.04+, Debian 10+, Fedora 33+, CentOS 8+, and Arch Linux. Installation can be done via one-click installation through APT/YUM repositories or manually with .deb or .rpm packages. The Linux client supports all core features including the WireGuard protocol, split routing, and the Kill Switch.

Yes, the Flagship version of Xiaoheiniu Accelerator includes a dedicated static IP address. Static IPs are especially useful for scenarios like remote access to corporate networks or NAS, running services that require a fixed IP, and avoiding verification challenges due to frequent IP changes. The static IP is exclusively assigned to you and will not be shared with other users.

Xiaoheiniu Accelerator comes with robust leak protection mechanisms: DNS leak protection ensures all DNS queries are resolved through encrypted connections; WebRTC leak protection prevents browsers from exposing your real IP through WebRTC interfaces; IPv6 leak protection ensures that IPv6 traffic is also safeguarded. You can use the built-in leak testing tool in the Xiaoheiniu Accelerator client or visit third-party testing sites to verify your protection status.

Xiaoheiniu Accelerator's custom obfuscation protocol disguises accelerator traffic as regular HTTPS traffic, effectively countering deep packet inspection (DPI) technologies. In environments with strict network restrictions, Xiaoheiniu Accelerator's obfuscation mode can help users keep a stable connection to a free internet. However, please be aware that Xiaoheiniu Accelerator advocates for the responsible use of accelerators in compliance with local laws.

Xiaoheiniu Accelerator supports various 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 certified secure gateways, ensuring the safety of your payment information.

Xiaoheiniu Accelerator has deployed over 3000 servers in more than 80 countries and regions worldwide. Major coverage areas include: North America (30+ cities in the USA, 5 cities in Canada), Europe (countries like the UK, Germany, France, Netherlands, Switzerland, etc., totaling 25+), Asia-Pacific (including Japan, South Korea, Singapore, Australia, India, etc., totaling 15+), South America (Brazil, Argentina, Chile, etc.), and the Middle East and Africa (UAE, South Africa, Turkey, etc.).

Yes, Xiaoheiniu Accelerator offers extensions for Chrome and Firefox. The browser extensions run lightweight, encrypting only the traffic within the browser (without affecting other applications). They are especially suitable for scenarios requiring rapid IP location switching, such as cross-border shopping comparisons. The browser extensions also include built-in WebRTC leak protection and ad-blocking features.

Xiaoheiniu Accelerator provides multiple customer support channels: 1) 24/7 online chat—visit the Xiaoheiniu Accelerator official website for real-time conversations with customer support, with an average response time of under 2 minutes; 2) Email support—send an email to support@vpnjs.net, typically receiving a reply within 24 hours; 3) Help center—featuring hundreds of detailed tutorials and troubleshooting guides. Our customer service team provides bilingual support in Chinese and English.

The Lightning and Flagship versions of Xiaoheiniu Accelerator include built-in ad-blocking and malicious site protection features. This function operates at the DNS level, maintaining a blacklist of over 1 million domain rules to block ad trackers, malware domains, and phishing sites during the DNS resolution phase. This method is more efficient than conventional browser ad-blocking plugins, as it prevents unwanted connection requests at the network level.
