At some point, all mobile devices (primarily laptop computers, but also smart phones, and portable printers) need to be connected to AC power to recharge or to function. Even if the devices are connected to the wall outlet for a short time, it is still at risk of surge damage or line noise distortion. Tripp Lite's Mobile Office Surge Suppressors lets users take high-quality protection on the road. Compact, Portable Housings: Mobile Office Surge Suppressors feature high-impact housings that are strong enough to stand up to any application, but that are small enough and light enough to slip into a briefcase or laptop bag. Select models feature retractable plugs to prevent equipment scratches during transit. High Protection Density: Mobile Office Surge Suppressors pack the high joule protection ratings of larger models into small, compact cases. This allows users to apply the same level of protection for its mobile equipment as it does for the desktop equipment back at the office. Mobile Office models are available in a variety of outlet, cord and case configurations. Up to $50,000 Ultimate Lifetime Insurance covers connected equipment against surge damage for life!
