Best Solar Powered Water Bottles

Are you the type that stays true to the rallying call of eight glasses of water daily? While this mythical idea depends on many factors like weather, age, and physical activities, there is a smart way to stay hydrated. You need a solar-powered water bottle. The bottle comes in different shapes, sizes, and functionalities. 

Besides, nothing is smarter than adopting renewable energy like the sun to power every aspect of your life. The energy can never be exhausted, and the only limitation is turning the sun’s magnetic rays into a source of electricity. That is exactly what a solar water bottle is designed to do. As the globe shifts to sustainable energy and zero-greenhouse gas emission, incorporating clean energy into every gadget in your house is a good idea: no refueling, free energy from the sun, no pollution, and minimum operational costs.

What is a solar water bottle?

A solar water bottle is a container for holding liquids fitted with a solar system. Different from the usual functionality of storing water, it has much more. It features a mini-solar panel that turns energy from the sun into electricity.

The power output is a light source and power charge for light-duty electronic devices. Additionally, the bottles come with a strong energy storage capability. The energy is useful in powering devices and has much more functions than your ordinary water bottle.

The three-in-one functionalities, flashlight, lantern, and utility source of power, make the bottles ideal for energy backup and outdoor activities that require an additional source of electricity. Below we check how a solar bottle operates.

How does a solar water bottle work?

A solar bottle absorbs the sun's rays and converts them into stored energy. Solar-powered water bottles are fitted with a solar panel at the top. Once it has drawn the energy from the sun, the gadget can hold it.

The battery for energy storage capacity varies from one solar water bottle to the next. Once the energy has been drawn from the sun and stored, it can power an in-built LED lighting feature. That is not all. Part of the output can charge phones, speakers, iPhones, or iPads.

All these functionalities are aside from the normal functions of storing drinking water. Despite holding these functions akin to any solar system, the bottles have adequate water storage space. Depending on the brand that you pick, some have extra storage space.

Do solar bottle lights work at night?

Yes. All the solar bottle lights function perfectly well at night. Of course, provided you charge them during the day. The bottles pick energy from the sun pretty quickly and dispense it equally fast during the night or when in use.

Depending on your brand, a typical solar bottle light at night could give you between 8 to 12 hours of bright light. That is not all. The bottles can also send SOS signals. The feature can help you make a distress call in an emergency when camping outdoors.

Why get a solar water bottle?

Solar water bottles have several functionalities in one handy water container. You will get a power bank, a water drinking bottle, and lighting. If you love off-grid living, stay in areas prone to a power blackout, or want to be a clean energy champion, you need a solar bottle.

A solar water bottle is perfect for outdoor activities like walking, jogging, canoeing, kayaking, or water skiing. Its lighting system is a great companion for off-grid. They work instantly once fully charged and turned on.

Suppose you are none of that and want a bottle with something extra and powerful. A solar-enabled bottle works perfectly well. You can carry it to the gym or office or keep it at home for routine usage. With the solar plastic bottle, you get an extra power output that is eco-friendly and pollution-free.

Now that you know what a solar bottle is and what it is used for, you need to get the right one that can serve you longer and more efficiently. That means buying from a reputable brand. We take a quick look at what to check when shopping for a solar-fitted water bottle.  

How to choose a solar water bottle?

Features 

A typical solar-powered water bottle has different features. Key among them is an in-built battery. Here, you should check on the capacity of the battery to know if it suits your backup power needs. A good one should have a longer battery life with energy-saving options. 

Also, look out for the brightness of the inbuilt LED lighting. Most solar bottles come with up to 100 lumens of brightness. The other important aspect is the charging ports and the shipping kit. A good solar bottle should give you enough power for your devices and must keep the stored liquids warm or cold.

Design

When buying a solar water bottle, design means everything. The bottles come in a sleek and compact design. Different bottles come in multiple colors to choose from. A good design also means ease of portability. When shopping for one, check the mounted carrying handle to know the ease of usability.

Portability 

When choosing a solar bottle, you should go for something sizable and less bulky. Most bottles are under 500 grams and easily fit your backpack. Most of the bottles found in the market are multifaceted. 

Material 

Any food or beverage container must be made from a safe casing that never contaminates your drinking water. The material should be non-corrosive, strong and durable, capable of withstanding heat, temperatures, and dust. That way, you will have clean drinking water. The solar bottles in this review comply with all the industry food safety standards. 

Power storage efficiency

You should check the ability of the solar bottle to store sufficient energy to back you up. How fast it can charge, store energy, and power your devices continuously is equally important when purchasing a solar bottle.

Cost

Getting a solar-powered water bottle should not break your bank account. You must compare the available bottles in the market to ensure that you don't incur exorbitant prices. Also, check shipping costs and whether the merchant has any money-back guarantee.
