Frequently Asked Questions (FAQs)

General Product Questions

Can I leave my Nokero product outside?

Yes. Our products are designed to endure the elements and withstand high temperatures outdoors. However, permanent exposure to rain, snow, and heat might degrade the electronics over time, potentially shortening the life of your Nokero product.

What if it rains? Is my Nokero product safe?

Nokero is durable, rainproof, and built of impact-resistant plastic. So, if your bulb or charger gets rained on, don’t worry about it! However, our products are not completely waterproof, so don’t submerge our products in water. Our products can also withstand snow, but will last longer if not exposed to daily freezing/thawing.

Can I charge my Nokero product when it’s cloudy?

All Nokero products charge even when it’s cloudy. However, charging in cloudy conditions takes much longer and is muss less efficient. We encouraging saving your product for sunnier days when you can get the most out of the sun’s energy.

 How do I take care of my Nokero product?

Taking care of your Nokero product is easy. Simply place your Nokero device in direct sunlight to charge during the day and take it down at night to use as a light. Use a lightly damp towel or cleaning solution to carefully remove any sediment that collects on the solar panel over time. If you notice your device not working, it may be time to replace the batteries (please refer to FAQ: “how do I change the battery?” for more complete details). Lastly, try to avoid letting your device sit in standing water and then you will be ready to enjoy hours of clean energy.

How long will the power remain in my Nokero product?

Once the sun has charged your Nokero device, the generated power remains in the device for up to a year. However, the longer you wait, the harder it is for our batteries to retain that charge. We encourage you to charge your device before you think you will use it or every few months if preparing for a future emergency.

How do I make sure I get the most sun during the day?

To make sure you’re getting the most sun during the day, position your Nokero device to face the sun. If you plan on leaving it out in the sun for a while, a safe bet is to face the solar panel south (unless you’re in the Southern Hemisphere—face north!). If you are using one of our products with a rotating solar panel feature, tilt the panel at a 45 degree angle when charging to best optimize direct solar contact. The best times to charge your device are between 9 a.m. and 4 p.m.

Nokero Light-Specific Questions

What’s the best way to charge a Nokero bulb?

To get the best charge, hang the Nokero bulb in full, direct sunlight during the day and tilt the solar panel at a 45 degree angle towards the sun to get the most sunlight possible. If you won’t be around to tilt the bulb throughout the course of the day, hang the bulb in a high-sunlight area and tilt the panel facing south (unless you’re in the southern hemisphere!). Don’t charge from behind a window. Also, while our bulbs can still charge on cloudy days, they charge better and much faster on sunny days.

How do I change the battery?

To change out the battery in your Nokero Crestone (N200) or Shavano (N220) light bulb, unscrew the plastic frosted dome and remove the batteries from their enclosed compartments. To remove the battery from the N400 window flashlight, simply pull down the plastic battery cap on the back of the device and remove the battery normally.

How much light do Nokero bulbs produce?

Here is a breakdown of all our bulbs currently on the market and how much light they produce:

  • Crestone (N200) and Crestone Pro (N210C): 13 lumens (High), 5 lumens (Low)
  • Shavano (N220): 29 lumens (High), 14 lumens (Low)
  • Antero (N400): 16 lumens
  • Ed (N50): 6 lumens
  • LED SHED: 20 lumens

Simply put, a lumen is a measure of the total “amount” of visible light emitted by a source. The normal output from a 60-watt incandescent light bulb is about 740 lumens.

My light won’t turn on. What’s wrong?

If your Nokero light won’t turn on, first make sure that you are in a dark space. Each bulb has an integrated light sensor that detects how much light is in the room or outdoors. This feature ensures your light runs only when it needs to. If you are in a dark or dim area and the light still won’t turn on, it may need to be charged. In this case, wait and charge the device in the sun for 8-12 hours before trying again. If the light still isn’t working, you may need new batteries. Our batteries typically last for at least 500 cycles. You can replace the batteries with standard alkaline batteries if accessible or more preferably with a NiMH rechargeable battery to allow the solar panel to repower the light. If all these suggestions aren’t working, contact our support team at support@nokero.com and we will help you with the next steps.

How durable are Nokero lights?

Our Nokero lights are very durable and are designed to endure being dropped, scraped, squashed, baked, pinched, bumped, nicked, kicked, rained on, snowed on, hailed on and, of course, being handled by curious children. We use durable ABS plastic and all our products are shatterproof. Our products have been known to rust over long periods of time, but none of the internal circuitry is typically affected. If one of our products breaks and you think it shouldn’t have, let us know and we can send you a new one.

What are common uses for Nokero bulbs?

Nokero light bulbs can be used anywhere you need light off the grid. Popular uses are home and patio lighting, marine lighting, camping, cooking, outdoor recreation, reading, and anything else you can think of! Our bulbs can also provide emergency lighting during unexpected blackouts or natural disasters.

Nokero Charger-Specific Questions

How do I charge a Nokero phone charger?

With our family of Nokero phone chargers, charging your device is extremely easy. Simply connect your phone to one of our solar chargers and place the panel in direct sunlight. To ensure a full charge, make sure the panel will not be shaded and avoid charging on cloudy days if possible.

How long does it take a Nokero charger to charge a cellphone?

  • P101: 3 Hours
  • P102: 1.5 Hours
  • Raycel: 2.5 Hours

How do I connect my Nokero charger to my cellphone?

To connect a Nokero P101 or P102 to your cellphone device, simply insert the USB into the charger and place the correct adapter at the other end. Insert into the cellphone jack and wait a few seconds to ensure charging has begun. To connect a Raycel charger to your cellphone, first remove the battery from your cellphone. Then slide down the clamp on the back of the Raycel enough to fit the battery. Slide the positive and negative pins until they fit nicely into the corresponding positive and negative jacks in the cellphone battery. The left pin is positive and the right pin is negative. Once the battery is secure, check the charge indicator light to make sure power is flowing into the battery.

My phone won’t charge, what’s wrong?

First make sure you are using the correct adaptor to connect to your cellphone. The P101 and P102 come with three adaptors for different popular cellphone models. Then make sure your Nokero charger has sufficient charge. Place it in the sun for a few minutes and then connect your cellphone. If you are using the Raycel, make sure the positive pin is going into the positive input jack and the negative pin is going into the negative input jack on your battery. If your phone still isn’t charging, email us at support@nokero.com and we will help diagnose the problem.

How durable are Nokero chargers?

Like our family of Nokero lights, our chargers are also very durable. We use safe ABS plastic and all our products are shatterproof, weatherproof and designed to endure everyday drops, scrapes, and crunches. If you believe your Nokero charger broke unnecessarily or before it’s time, let us know and we can send you a new one.
