About Home Tech & Connectivity

Getting the most out of your devices usually comes down to the unglamorous stuff: the right Wi-Fi setup, the right cable, the right amount of power. PickShack's tech tools handle that math, from estimating how fast your internet really needs to be for your household, to picking a power bank that will actually recharge your laptop on a trip, to diagnosing why your Wi-Fi drops in the back bedroom. Three areas cover networking and Wi-Fi, power and charging, and device testing and comparisons. These are practical calculators and guides for anyone who'd rather solve the problem once than keep paying for upgrades they don't need.

Frequently asked questions

How fast does my internet need to be?

For most households, 100 to 300 Mbps is plenty. Streaming 4K takes about 25 Mbps per stream, video calls run on 5 Mbps, and gaming needs low latency more than high throughput. Our internet speed calculator estimates based on the number of users and what they actually do online.

Why is my Wi-Fi slow in certain rooms?

Usually one of three reasons: distance from the router, thick walls (especially brick, tile, or metal), or interference from other devices. Our fix-slow-wifi-at-home guide walks through how to diagnose and fix each cause, including when a mesh system is actually worth it.

How do I pick a power bank for a laptop versus a phone?

A phone needs 10,000 to 20,000 mAh. A laptop needs 20,000 mAh or more with USB-C Power Delivery at 45 to 100 watts. Our power bank sizing tool matches capacity and wattage to your specific device.

Are USB-C cables all the same?

No. They vary in data speed (USB 2.0 to USB 4), power delivery wattage (up to 240 watts), and whether they support video. A cable that charges your phone fine may not be fast enough for your laptop or monitor. The USB-C cable picker helps you match cable to use case.

Can I test device quality or speed at home?

Yes. The devices section includes simple in-browser tests for display quality, audio sync, internet speed, and input latency, plus comparison tools for picking between models.
