Have you ever experienced the discomfort of having cold hands while spending time outdoors, whether it's during a walk with your dog or simply due to your tendency to get cold hands easily? Cold hands can be more than just an inconvenience; they can make you feel cold throughout your entire body. With the chilly season now behind us, I set out to address this issue in a whole new way. I recently purchased the CozyCharge electric hand warmer, and while hand warmers themselves are not a novel concept, this one has truly impressed me. In this review, I'll share my experience with the CozyCharge electric hand warmer and help you decide if it's the solution you've been looking for.
Is It CozyCharge Like Any Other Hand Warmer

CozyCharge stands out from the typical hand warmers on the market as a versatile 2-in-1 device that combines the functionality of a hand warmer and a power bank. It's designed to provide you with instant warmth for your hands and the convenience of charging your phone wherever you are. What sets CozyCharge apart is its rechargeable feature, making it a daily go-to without any hesitation.
While traditional hand warmers do the job, they often come with a drawback – they require activation time and can become a recurring expense if used frequently. With CozyCharge, you get the benefit of quick warmth and the ability to recharge it after every use, making it a cost-effective and practical choice.
What It Has To Offer
CozyCharge offers a range of features that make it a valuable addition to your winter gear:
Adjustable Temperature Settings
CozyCharge boasts three adjustable temperature settings, with the capability to reach up to a toasty 140°F/60°C, depending on your chosen setting. These settings provide instant relief from the discomfort of numb and painful hands caused by frigid winter weather.

Ergonomic Design
Shaped like a bar of soap, CozyCharge features a smooth and lightweight surface that fits comfortably in your hands. It emits gentle, soothing heat that not only eases aches but also improves circulation. What sets it apart is its dual heating surfaces, allowing you to grip it with both hands and enjoy enhanced warmth.

Compact and Portable
CozyCharge's compact and portable design is its primary feature. It's designed to slip into your pocket or snugly fit in the palm of your hand. This portability makes it a versatile companion for various activities, from skiing trips and outdoor adventures to solitary walks or dog outings. The CozyCharge can deliver hours and hours of safe, long-lasting heat and power.
Muscle and Joint Relief
Beyond its use as a hand warmer, CozyCharge has been reported to provide significant relief to those experiencing muscle aches or joint pain due to colder temperatures. For optimal safety and comfort, when using it against sensitive areas such as wrists or behind knees, it's advisable to place a cloth between your skin and the unit to prevent potential burns.

Built-In Power Bank
CozyCharge goes beyond keeping your hands warm; it also functions as a built-in power bank. This handy feature allows you to charge your smartphone, Bluetooth headphones, and other USB devices while on the move. However, it's important to note that you cannot simultaneously use the hand warmer and charge your phone.

While CozyCharge offers the convenience of being a power bank, it's important to set realistic expectations. It serves as a reliable source for charging your essential devices when needed, making it a versatile companion during winter activities.
Is It Safe To Used By Kids?

Rest assured, CozyCharge is designed with safety in mind, making it suitable for use by children and the entire family. It incorporates multiple built-in protection circuits that effectively prevent overcharging and short-circuiting. In the event of any such issues, these circuits automatically shut off the unit, ensuring the utmost safety during use. You can enjoy the warmth and convenience of CozyCharge with peace of mind, knowing that it prioritizes the safety of your loved ones.
How to Properly Use CozyCharge?
Upon receiving your CozyCharge, it's advisable to begin by charging it until it reaches full capacity. Most electronic devices, including CozyCharge, may come with only a partial charge initially. In the event that your CozyCharge arrives completely drained, connect it to the charger for a period and see if it starts charging. If it doesn't, reach out to customer support for assistance. Now, let's delve into the specifics.

CozyCharge boasts a user-friendly design. On its lower end, you'll find an output port with a control button positioned just above it. On the right side, there are three indicator lights, serving dual purposes: indicating the selected temperature setting and displaying the remaining battery charge.
To use CozyCharge as a hand warmer, follow these steps:
Press and hold the control button for approximately 4-5 seconds to power on the warmer mode. The appearance of red lights indicates that it's powered on. This extended press serves as a safety feature, ensuring accidental activation is avoided.
CozyCharge offers three temperature settings for your comfort:
- One flashing red light signifies low temperature.
- Two flashing red lights indicate medium temperature.
- Three solid red lights represent high temperature.
Upon turning on the CozyCharge, it defaults to the lowest temperature setting. To adjust the temperature setting:
- For medium temperature, briefly press the control button once.
- For high temperature, press the control button again briefly.
- To turn off the warmer, perform a long press of 4-5 seconds. When it's powered off, no indicator lights should be illuminated.
Note: Please be aware that if you quickly press the button twice in succession, blue lights may activate on your device. These lights will turn off automatically after 40 seconds.
If you're using CozyCharge to charge your phone, a single blue light will appear and remain lit throughout the charging process.
When it's time to recharge the CozyCharge unit itself, connect it to the charger, and you'll observe alternating flashes of red and blue lights. Once the unit is fully charged, only one solid blue light will be visible.
Remember, it's crucial not to utilize the hand warming feature while simultaneously charging the device, as this could lead to overheating of the CozyCharge unit. You should use either the warming function or the charging function at one time, not both together.
Other Recommended Precautions
Since the CozyCharge serves both as a hand warmer and a power bank, there are some important precautions to keep in mind for its safe and effective use. Just like with any other product, it's crucial to adhere to the provided instructions. Never attempt to disassemble or open the CozyCharge unit, and avoid piercing it with any metal objects.
If you anticipate not using the unit for an extended period, such as during the warmer months of the year, remember to charge the unit every three months to maintain its optimal battery life. Additionally, be cautious not to place the unit near a direct heat source or an open flame. It's essential to keep the unit dry and prevent it from being submerged in water. Lastly, avoid leaving the unit exposed to prolonged sunlight.
By following these precautions, you can ensure the safe and reliable operation of your CozyCharge device while enjoying its dual functionality as a hand warmer and power bank.
How Much Does CozyCharge Cost and Where to Get One?
When it comes to pricing, CozyCharge offers a balanced option that falls between the lower-priced and more premium hand warmers on the market. It's budget-friendly while still delivering impressive heat output compared to some pricier alternatives.
While I've explored various sources, I found that CozyCharge is primarily available for purchase on its official website. It's essential to exercise caution when seeking to acquire one elsewhere, as authenticity and quality may vary.

Currently, the official website lists CozyCharge at $34.95. Moreover, there are enticing deals available, such as buying two and getting one free, or purchasing three and receiving two free units. These deals also include free shipping, adding extra value to your purchase. If you're in the market for a rechargeable hand warmer that offers a combination of affordability and performance, visiting the official website and taking advantage of these limited-time offers is a wise choice.
In summary, CozyCharge is a commendable hand warmer that provides excellent features at a reasonable price point. Its effectiveness, safety features, and budget-friendly options make it an appealing choice for keeping your hands warm during colder times. Don't let the chill get the best of you; stay cozy with CozyCharge.

I bought 2 cozy charges and got one free. Only one of them would take a charge-blue light blinking. Tried the other 2, but no blue flashing light. Any advice?
