8 best 4port usb hubs
A 4-port USB hub is a device that allows you to expand the number of available USB ports on your computer. Here are some general points about 4-port USB hubs:
Purpose: A 4-port USB hub is used to connect multiple USB devices to a single USB port on your computer. This is especially useful if you have limited USB ports on your computer or if you need to connect multiple peripherals like external hard drives, printers, cameras, and more.
Port Types: These hubs typically come with standard USB Type-A ports, which are the rectangular USB ports that have been widely used for many years. Some may also offer USB Type-C ports for compatibility with modern devices.
Data Transfer Speed: The speed at which data is transferred between the hub and connected devices is an important factor. USB 2.0 hubs have a lower data transfer rate compared to USB 3.0 or 3.1 hubs. USB 3.0 and 3.1 hubs are faster and more suitable for high-speed data transfers.
Power Source: Some USB hubs are bus-powered, which means they draw power from the computer's USB port. Others are self-powered and come with an external power adapter. Self-powered hubs are better for connecting high-powered devices like external hard drives that may require additional power.
Compatibility: Ensure that the USB hub is compatible with your operating system (Windows, macOS, Linux) and that it supports the USB version of your computer (e.g., USB 2.0, 3.0, 3.1).
Design and Form Factor: Consider the physical design and form factor of the hub. Some hubs are compact and portable, making them suitable for travel, while others may have a more robust design for stationary use.
Brand and Quality: Reputable brands like Anker, TP-Link, Belkin, and AmazonBasics are known for producing reliable and high-quality USB hubs.
Additional Features: Some hubs may come with additional features like LED indicators, individual power switches for each port, or compatibility with charging devices.
Price Range: The price of 4-port USB hubs can vary depending on factors like brand, data transfer speed, and additional features. In general, they are relatively affordable.
Remember to choose a USB hub that fits your specific needs and requirements.Always ensure that it's compatible with your devices and operating system.

User questions & answers
Question: | Can my child swallow these if I cut them into pieces instead of chewing them? He hates the taste |
Answer: | MY kids never ate them |
Question: | Do kids one taste the same as nutri stars |
Answer: | No. They do not taste the same according to my four children. They all prefer the taste of the NutriStars (but they have to take two instead of one). They say NutriStar tastes like fruit punch, and the Kids One tastes like "fruit punch from an island, like not real fruit punch." |
Question: | Should this be stored in the fridge after opening? I saw the comments about growing mold etc |
Answer: | Idk ab mold but given the probiotic i would store in fridge |
Question: | I recently ordered these again and this time the stars are yellow and my 2.5 year old won't eat them now. Did they recently change their formula |
Answer: | Not that I know of. My kids and family have taken rainbow light for many years and always happy but the two times I bought on Amazon I've noticed they had moisture in the bottles and extremely broken up. I stopped buying from Amazon and now buy direct from rainbow light. The quality is so much better and they do not come smashed up. Most of the time you get 15-25% off. |

User questions & answers
Question: | Why is the teen girl’s bottle $7 more than the teen boy version? Comparing labels, they are almost exactly the same thing |
Answer: | Rainbow Light Vibrance, Teen Girl’s plus Healthy Skin Support, and the Young Men’s plus Healthy Skin Support, have organic whole food blends added to the nutrients, and are non-GMO verified. Basically specific ingredients formulated in these products cost more in comparison to the Active Health Teen. Please do not hesitate to contact Rainbow Light Direct customer care with any other questions you may have. |
Question: | Do these vitamins contain gelatin |
Answer: | Folate |
Question: | Why are these significantly more expensive than the RL active teen health, for the same amount of servings |
Answer: | I just want to note that your daughter is capable of swallowing large pills. The issue is the brain does not register it as food and the gag reflex kicks in. I have a 7 yr old boy who can swallow 8 pills at a time of all sizes. one being a omega 3 pill and they are HUGE!!! The key is to showing them that they already swallow something much larger when they eat. Have her chew a bite of bread and spit in into her hand right before she swallows. Then put the pill next to it. Her brain will see it and she should not have an issue after the first two tries. Does not work for everyone but it is worth a shot. |
Question: | What form of folic acid |
Answer: | Swallow it whole. It's med-large size, but hard so maybe you could cut it into 2 pieces? My 14 & 16 yr olds take 1ea 2x a day-no problems. |

User questions & answers
Question: | How long is the power cord |
Answer: | Yes. |
Question: | How long is the provided USB cable |
Answer: | It’s run by a rechargeable battery the laser specs are in the description. |
Question: | Does this work on xbox one |
Answer: | I had the same question. What I do is slowly rub it over a long or wide muscle. Or hold it in place for a sore spot In one location like my elbow I hit. |
Question: | Is it compatible with the latest version of Mac OS |
Answer: | Sealed. Ships from ATANG headquarters in California, not directly from Amazon |
Question: | Can this device used for hair growth? 650nm laser is same as what is used in hair growth therapy |
Answer: | Yes you can use the laser and micro current everywhere except the carotid triangle and the eyes |
Question: | What is the wattage |
Answer: | The kit contains the device, a large tube of the gel, the charger, instruction DVD and a small flyer w/instructions/info. |
Question: | What is the best way to use this? Hold it in one place (for how long?) or constantly move it around? The directions are not very detailed |
Answer: | It would be nice if it had that feature.i leave mine plugged in for a minimm of 5 hours..when it needs a charge , it becomes dimmer |
Question: | is this product brand new in box and coming direct from Amazon or a reseller |
Answer: | Yes, the max power of the LaserTouchOne's laser is less than 1mW. That is intentional - studies have shown that lower powered lasers are actually more effective in delivering photonic energy to the cells. The cells' receptors are better able to absorb the low level laser and use it to create ATP (the fuel molecule that cells need), move nutrients in, move toxins out, and repair & heal. When used in combination with the microcurrent electrical stimulation delivered by the LTO during treatment, the results are exponentially more effective than just using a laser or e-stim device alone. |
