Tripp Lite INTERNET750U 750VA 450W Standby UPS - Compact Power Backup

In this review the Tripp Lite INTERNET750U is assessed as a compact standby UPS aimed at small home offices and desktop setups that need short-term battery backup and surge protection. The bottom line: it is best for users who want a space-saving unit that will keep a single PC, router or small set of electronics running long enough for a safe shutdown. Its standout advantage is the combination of widely spaced outlets and built-in TEL/DSL surge suppression that protect both power-hungry transformer plugs and connected telephone or modem lines.

Key Features

• Battery-derived AC output: Provides temporary power during blackouts and brownouts so sensitive electronics can be safely shut down without data loss.
• Widely spaced outlets: The layout accommodates large transformer plugs without blocking adjacent receptacles, letting you use more devices at once.
• TEL/DSL line surge suppression: Protects modems, fax machines and phones from line surges to reduce the risk of damage during storms or utility spikes.
• USB connectivity: Enables communication with a computer and use of the free PowerAlert software for automatic file save and safe shutdown.
• Space-saving housing: Ultra-compact, desktop or wall-mountable design fits in tight spaces where larger UPS units would not work.

Who It's For

The INTERNET750U suits home office users, small business owners or students who need short runtime backup for a single PC, external drive and network devices. Its compact footprint and widely spaced outlets are especially useful for setups with bulky power bricks and limited desk or shelf room.

It is not intended for users who require long runtime for many devices or whole-workstation backup; those needing extended runtime or support for larger server loads should look at higher-capacity or pure sine wave models instead.

Pros & Cons

• Compact form factor and optional wall mount make placement flexible in tight spaces.

• Built-in TEL/DSL surge suppression offers extra protection for network and phone lines in addition to AC protection.
