Charger seems to have both red and green lites flashing at the same time no sequence and both batteries connected read 4.0 VDC, are these chargers repariable or throw aways


Your manual is here. The section on charging states, that green blinking means your battery is fully charged but blinking red means that your charger is faulty. I would say repairable.

1. Plug the female connector of the AC power cord (supplied) to the AC receptacle on the charger and plug in the male connector on the AC power cord into the wall outlet.

2. The On/Off LED indicator is blinking RED, this is abnormal. Unplug AC power cord from the on-board battery charger and wall outlet. Charger may need to be replaced. Contact an Invacare dealer or qualified technician.

3. When the On/Off LED indicator light is Off, charger is Off.

4. When the Charge LED indicator light is YELLOW, the batteries are charging.

5. When the Charge LED indicator light is solid GREEN, the batteries are fully charged (as their condition will allow).

6. When charging is complete, unplug the male connector of the AC power cord from the wall outlet and then unplug the female connector of the AC power cord from the AC receptacle on the charger.

What can you advice me to do? i have a UPS SURTD5000XLI, indicating a red Led light, but when i remove it from the AC power source, the Red Led also remove & when i flog it again to the AC Source it...


Is red light on for overload or for battery?
If on overload, try reducing the load on the UPS. If red light on overload persists buy a new UPS (overload fault hard to repair).

Red light on battery - replace the batteries.

Red light on boost or buck, may mean that the nominal voltage of ups and the limits need to be changed/corrected.

BROOKSTONE HDMI PROJECTOR 801143 DOES NOT CHARGE


The Brookstone manual claims it will fully charge after 3-5 hours, but it takes much longer then that. Mine does not indicate green light, but it seems it stops blinking red when its fully charged. After that it run on power directly from the ac-adapter.

If you keep it connected to the AC-adapter after it have stopped blinking red (do not disconnect it at all), it will start to run on the adapter and will not turn off. You will feel the AC-adapter gets hot while its running, something it does not while regular charging.

If it still dont stop blinking red after having it connected to power for 3 days, your AC-adapter is probably faulty. This happened to me, and after allot of research I found this replacement from a US seller on ebay (only five dollars included shipping).

Good luck with your projector. It a really cool little thing, but it has some design flaws.

Best regards.

Battery indicator?


Hi there.
Sounds like the battery could be faulty.
The diagnostic procedures from the Dell User Guide are as follows:

Total Power Failure When Using a Battery
If an AC adapter is not connected to your computer, the computer's power source
is a battery. If the battery indicator flashes amber or is a steady amber, the
battery needs to be charged. If the battery is flashing green and amber, the
battery may be defective. To troubleshoot this problem, use the following
procedure.
1. Turn off the computer and peripherals, and disconnect them from AC power.
2. Reseat each installed battery by removing it and then replacing it.
3. Turn on the computer. Does the green power indicator light up?
Allow one minute for the computer to initialize its components before checking
for signs of power.
Yes. Continue to step 4.
No. Use the AC adapter to connect your computer to AC power. If the computer
operates normally when using AC power, go to step 7. If the computer does not
boot when using the AC adapter, see the previous subsection, "Total Power
Failure When Using the AC Adapter."
4. Does the battery indicator flash amber or show a a steady amber light?
Yes. The battery needs to be charged. Go step 5.
No. Go to step 7.
5. Connect the computer to AC power, and fully charge the battery.
For instructions, see the topic titled "Charging the Battery" in the online
System User's Guide.
6. As the battery charges, does the green battery indicator light up?
Yes. Go to step 9.
No. Go to step 7.
7. Is the battery indicator flashing green and amber?
Yes. Your computer may be in a hot environment. Charging the battery in this
condition may affect the life span of the battery. Continue to step 8.
No. The problem is resolved.
8. Disconnect the computer from AC power. Is the the battery indicator still
flashing amber?
Yes. You may have a defective battery. Continue to step 9.
No. The problem is resolved.
9. Remove the battery, and press its test button. Is the uppermost indicator in
the charge gauge of the battery flashing?
Yes. You have a defective battery. Continue to step 9.
No. The problem is resolved.
10. If a spare battery is available, fully charge it, and then install it in the
computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective.

Good luck

Power indicatoror


From the manual:

"Attach the barrel tip of the AC Charging Adapter to the AC Charging port of the POWER TO GO® and plug the standard two-prong plug into an appropriate, functioning 120 volt AC outlet. The red Battery Status LED indicator will flash, indicating a proper connection has been made and the unit is charging. The green Battery Status LED indicators will gradually light as the charge level rises. The POWER TO GO® must be charged for approximately 11-17 hours prior to first use. All Battery Status LED indicators will be lit solid (the red indicator will stop flashing) when the unit is fully charged.
