Everything you ever wanted to know about the Jonta
Do I need to do anything before I use it?
For best results, the battery requires a conditioning charge before first use, or after long periods without use. This can be done by administering several vigorous 30-second wind cycles. Alternatively this can be done by fully charging the battery using the wall adapter (if you have one). The product can, however, be used immediately in the wind-up mode if required.
How do I change the light bulb?
The light is an LED (light-emitting diode) with up to 100 000 hours of useful life and never requires replacement.
How long will a fully charged battery retain its charge?
The battery will retain about 75% of its capacity after 1 month, 55% after 2 months, 40% after 3 months and 15% after 6 months.
Can I over-wind the unit - does it ever stop you from winding?
No, you cannot over-wind the internal mechanism. It consists of simple gearing which drives the alternator, providing power to the internal battery.
Will I damage the product if I crank the handle in the opposite direction?
No, the winder handle can be cranked in both directions.
Is the product waterproof?
No, it is not waterproof. It is splash proof and will work in rainy conditions.
How long should my Jonta shine for?
With a fully charged battery, the Jonta will shine for approximately 24 hours on normal beam (Energy Saving) or 2 1/2 hours on high beam. A 30-second wind at 120 rpm will provide about 10 minutes of shine time on normal beam.
What is the indicator light for?
The indicator light is an optimum charge level indicator. This means that it will only illuminate when you are winding the handle at the best speed to generate the ideal amount of energy.
How long does it take to fully charge the battery?
Using the wall adapter, it will take about 6 hours to fully charge the battery. Or using the crank, it will take about 40 minutes, if you constantly wind at the optimum speed as indicated by the green charge level indicator.
What is the life span of the internal battery?
The internal battery is good for 500 cycles when fully charging the battery and 10 000 cycles when using the winder mechanism for 30 seconds.
Why is it named Jonta?
Freeplay Energy plc is committed to a world of responsible energy. This commitment extends beyond the environmental impact mitigation of our products to the sustainable provision of energy in developing communities and humanitarian initiatives. The names we choose for our products tell some of our stories:
| Isolation is the greatest barrier to the alleviation of poverty. Radio can reach those isolated by disease, geography, language, conflict, illiteracy or poverty. Millions of dollars are spent each year to create developmental radio programming, yet the audience, the poor, may never hear it. There is no electricity supply in most rural areas and the cost of batteries is prohibitive. Critical information that can help prevent deadly diseases, improve hygiene, increase agricultural productivity, teach animal caring skills or warn of an impending flood may therefore never be heard. Jonta’s father and mother died of AIDS leaving him to look after his five younger siblings, including a ten-month-old sister. Jonta symbolizes a generation in the history of humankind that is growing up without parents – and there are millions of such children. Built on the same trusted and dependable technology as this flashlight is Freeplay Energy plc’s Lifeline radio, a multi-band, self-powered radio designed specifically for providing dependable access to information across a broad range of humanitarian projects. The radio does not require batteries or mains electricity and can used anywhere. Engineered to operate in the harshest of rural conditions, it is rugged, robust and easy to operate. The Lifeline self-powered radio ensures sustainable access to radio to those most in need. Jonta will always have a hard life. However, for him and others like him, the Lifeline radio can offer the prospect of a better future – a future filled with information and knowledge of the outside world. |  |
The battery doesn't hold a charge any more; do I need to replace it?
Rechargeable batteries deteriorate over time, especially if drained nearly completely (to extend the life of your battery, limit how often that happens). However, in many cases they can be "conditioned" back to life. This can be done by administering several vigorous 30-second wind cycles. Alternatively this can be done by letting the product run from the battery until it stops, and then, with the product turned off, fully charging it using the wall adapter.
