Lost charger
ok I lost my charger for this light http://www.promaster.com/products.asp?product=7207
On the back of the light it says it wants a 5 volt positive tip charger. Any guess on the amperage? im thinking 500 MA maybe less? |

Re: Lost charger
Do you have any idea what kind of recheargeble battery is in there? Is it a Lithium-Ion? And how many mAh?
If you know it's a Li-Ion battery with say 2000 mAh, then you should be charging it with something between 1000 and 2000mA. Quote:
...and do you need just a power supply and the charger circuit is inside the lamp, or do you need a real charger, with electronics? If it is just a power supply, you should be fine with any kind of 5V power supply as long as it has enough mA (or more), but if you need a charger, it will be more difficult to get the right one. *edit* as far as I understand the tech specs on this light, you should only be needing a normal AC power supply, at least that is what they call it and what it looks like. So a normal 5V power supply with at least 1500mA should be okay (the tech specs say it is a Lithium Polymer battery with 3000mAh). If you use a power supply with more mA that shouldn't be an issue because the charger just draws what it needs. However, I am not an electrician, this is just an educated guess! I know I would personally be mad enough to try it, but I can't really recommend it to you! If you want to try it, be careful, Lithium rechargeables can explode badly when treated the wrong way... It would be safer to find someone who owns that lamp (or a store that sells it) and look at what the label of the power supply says exactly. |
