Choosing computers peripherals gets tricky when the items solve very different problems. One shopper may need a simple power cord extension, another may want two computers to share USB devices, and another may be outfitting several laptops with compact wireless mice. The best choice here depends less on a single winner and more on matching the product type to the exact connection problem on your desk.
Quick take
- Best for a simple cord need: Arista 6' Power Cord Extension for Computers and Peripherals - New Old Stock.
- Best for two-computer USB sharing: USB 3.0 KVM Switch 2 In 4 Out 2 PCs Sharing 4 USB Peripherals for Desktop Laptop.
- Best for four-computer USB sharing: USB 2.0 Sharing Switch for 4 Computers & Peripherals, LED Indicators, Easy Setup.
- Best multi-unit mouse lot: 10x Newton Peripherals MoGo MG100 STORABLE BT Mouse Fits IN Laptop cf port.
The biggest decision is whether you are solving a power reach issue, a USB-device sharing issue, or a mouse quantity issue. The two USB sharing products look related, but their computer count is different: one is centered on two PCs sharing four USB peripherals, while the other is built around four computers and LED-indicated manual control.
Listed price comparison
| Product | Listed price | Price bar |
|---|---|---|
| Arista 6' Power Cord Extension for Computers and Peripherals - New Old Stock | USD 11.99 | |
| USB 3.0 KVM Switch 2 In 4 Out 2 PCs Sharing 4 USB Peripherals for Desktop Laptop | USD 16.99 | |
| 10x Newton Peripherals MoGo MG100 STORABLE BT Mouse Fits IN Laptop cf port | USD 35.95 | |
| USB 2.0 Sharing Switch for 4 Computers & Peripherals, LED Indicators, Easy Setup | USD 53.35 |
The listed spread runs from $11.99 to $53.35, with the lowest-priced item 78% below the highest-priced item. That spread makes sense because the group includes a basic cord extension, two different USB sharing devices, and a 10-count mouse lot rather than four direct substitutes.
Decision matrix
Choose the Arista 6' Power Cord Extension when the job is simply extending power for a computer or peripheral. It is not a USB switch, mouse, hub, or device-sharing tool, so it should be treated as a targeted accessory rather than a workspace controller.
Choose the USB 3.0 KVM Switch 2 In 4 Out when two computers need to share multiple USB devices. Its title and description emphasize two PC inputs, four USB outputs, one-button swapping, and included USB cables. It fits a dual-computer desk better than a four-computer setup.
Choose the USB 2.0 Sharing Switch for 4 Computers & Peripherals when the computer count matters most. It is the only option here described around four computers, LED indicators, USB 2.0 compliance, and manual control. It is also the highest listed price, so its strongest case is the four-computer role.
Choose the 10x Newton Peripherals MoGo MG100 lot when the need is several compact Bluetooth mice rather than cables or switching. The title says 10x, and the description frames them as small travel mice that store in a laptop CF port. Charger included is marked no, which matters for planning accessories.
Concise product notes
Arista 6' Power Cord Extension for Computers and Peripherals - New Old Stock
This Arista cord is the cleanest pick when the need is straightforward: a six-foot power cord extension for computers and peripherals. The listed manufacturer part number is 78-1131, and the description presents a single included Arista extension cord. Its main advantage is focus; it does not try to manage USB devices or add wireless control, so it suits a simple power-routing need. The limitation is equally clear: it is marked New other and New Old Stock, and it only addresses power extension. Anyone needing computer-to-peripheral switching, Bluetooth input, or multiple shared USB ports should look at one of the other products instead.
USB 3.0 KVM Switch 2 In 4 Out 2 PCs Sharing 4 USB Peripherals for Desktop Laptop
This USB 3.0 switch is the more natural match for a two-computer desk. The product wording centers on 2 PCs sharing 4 USB peripherals, with one-button swapping and two USB cables included in the package description. It is especially relevant if the shared devices are common USB peripherals such as a keyboard, mouse, printer, scanner, or similar USB equipment named in the description. The tradeoff is that the setup is framed around two computers, not four. It also notes a 5V DC power supply port for higher-power devices, while the power adapter is not included, so that may affect how it is used with certain peripherals.
USB 2.0 Sharing Switch for 4 Computers & Peripherals, LED Indicators, Easy Setup
This sharing switch is the clearest fit when one set of USB devices needs to be shared across more than two computers. It is described for up to four computers and up to four USB devices, with manual switching and LED indicators to distinguish computers. It also lists USB 2.0 compliance and a 4-way feature, so the appeal is breadth of computer sharing rather than the USB 3.0 wording used by the lower-priced switch. The limitation is the listed cost and the USB 2.0 focus. If the desk only has two computers, the 2-in/4-out USB 3.0 switch may be a more direct match.
10x Newton Peripherals MoGo MG100 STORABLE BT Mouse Fits IN Laptop cf port
The MoGo MG100 lot stands apart because it is not a cable or sharing switch at all; it is a 10-count group of Bluetooth wireless mice. The product description positions them as small travel mice designed to go into a laptop CF port for charging and storage, and the attributes list wireless Bluetooth connectivity, a storable feature, and model MG-100-01-0003-01. This is the most quantity-oriented choice in the group. The limitation is practical: charger included is marked no, and the description says the units are untested, unused, and sold as is, with battery condition not stated as confirmed.
How to choose by desk setup
For a single computer setup, start with the problem. If the issue is cable reach, the Arista cord is the relevant item. If the issue is moving one keyboard, mouse, or printer between two machines, the USB 3.0 2-in/4-out switch is more closely aligned. If four machines are involved, the USB 2.0 four-computer sharing switch is the only product in this group explicitly built around that count.
For small offices, labs, or shared workspaces, the distinction between device sharing and device quantity matters. A sharing switch reduces repeated plugging and unplugging of USB peripherals across computers. A 10-pack of Bluetooth mice solves a different issue: putting a mouse with multiple laptops or users. The MoGo lot may be attractive when count is the main reason to buy, but its no-charger note and untested wording make it less simple than buying a single ready-to-use mouse accessory.
For mixed peripheral drawers, avoid buying the most complex item just because it covers more scenarios. A four-computer sharing switch is unnecessary if the actual setup has two machines. Likewise, a USB switch will not help with a power cord extension need. Matching the product type first is the fastest way to avoid the wrong accessory.
Final recommendation
For most shoppers comparing these computers peripherals, the best all-around desk-control pick is the USB 3.0 KVM Switch 2 In 4 Out 2 PCs Sharing 4 USB Peripherals for Desktop Laptop at USD 16.99, because it targets a common two-computer, four-USB-device setup without reaching the top of the price range.
Choose the USB 2.0 Sharing Switch for 4 Computers & Peripherals, LED Indicators, Easy Setup at USD 53.35 only when four-computer sharing is the priority. Pick the Arista 6' Power Cord Extension at USD 11.99 for a simple power extension need, and choose the 10x Newton Peripherals MoGo MG100 lot at USD 35.95 when the 10-count Bluetooth mouse bundle is the reason to buy.
