USB rechargeable lamp

[johngross]

Anybody use a lamp where the battery is recharged through a USB port? I guess like a cell phone, tablet, etc. If so does it hold a charge fairly well?

Of course I know it depends how much the lamp is used. The lamp we buy will be used just a few minutes a day, so probably less than 30 minutes a week of use.

If these type lamps, regardless of how little it may be used, still need charging every couple of days, I'll probably pass on buying one.

The picture below is an example of a USB lamp.

Thanks.

Well, FWIW, I have one of these

That I got as a Christmas gift LAST year. It's been sitting out in the garage for over a year now, and I just went and got it and turned it on, and it is still charged. I've never charged it or even taken it out of its packaging, so it has maintained the original factory charge for over a year.

I had some USB rechargeable lights that just seemed incredibly useful. I used the very brief intervals for about a year... the whole batch of 3 have failed now.

I'm not overly hopeful. But I need useful utility lights.

Rechargeable battery technology and low power consumption LED light technology have come a long way in the last few years. If I wanted one, I have no hesitation (but would, of course, do some research first.)

It’s probably like rechargeable LED flashlights. There’s good and bad, and an extensive price range. Some of the moderately priced stuff is pretty amazing compared to what was available just a few years ago...

Removeable batteries in the common lithium battery series (eg. 18650) are
better than "built-in", if you plan on keeping the light after the original
battery gives up.

I have a light that is about 3"x 4" with a long led bulb set up. Has a little "kick Stand" to position it. Thing can blind you. Stays bright for hours and is charged via USB port like a cell. Can also use its battery to charge my cell vial a large USB port on it. I also have 2 battery packs for stuff like this. You can cascade the battery packs, plug one into charger use its output port to run to second battery pack and then a phone or whatever. wait long enough and they are all 100%

I’ve been using this unit for over a year. I’ve dropped it many times and run it almost dead hundreds. It lasts about 6-8 hrs and recharges in 2-3 hrs. Amazing gadgets. I was skeptical but no longer. As my other drop lights die I will replace them with one of these. The usb charging LED lights are inexpensive and really work!

REALLY!!!

My Dad loved the "built in" rechargable lights, but they were always failing when needed the most, mostly during hurricane season and power outages in the Keys.

I've found that getting *quality* rechargable batteries, Eneloop by Sanyo, not the american made garbage and even cheap lamps was a winning combo. One LED light from HD cost a whopping $10 and has been going strong for ~10 years now. Uses 3 AAA batteries into a "C" adaptor and easily fits into a pocket. One can also find 3 AA into a "D" adaptor for even brighter light.

The Eneloops aren't cheap, but are a good value. Up to 2,000 recharges and they will retain 80% of a charge after 5 years. My oldest ones are over 10 years old and still going strong. The lights give out way before the batteries do, but the technology is really coming along, along with lower cost.

I've had exceptionally bad luck with the multi AAA battery adaptors. China low bid junk. I prefer AA batteries.
Also, I've found otherwise good cheap lights like the promo special Harbor Freight lights where the batteries can jump out of place. A bit of rubber weather stripping over the batteries and force to screw it together has helped.

Thin rubber bands work well to keep them in the holders too.

Is the OP asking about a "lamp" or a Flashlight??. Yes, some folks call a flashlight a "lamp"

You can usually use an 18650 instead of the AAAx3 adapters--
and get better performance, too.

Yeah, my post wasn't about a specific type of light - but rather it was intended as an answer to the battery life part of his question.

But FWIW, although mine might be described as a "flashlight" - because it does indeed have a spot-type light on one end, it could also be described as a "lamp" - because it also has a strip of LEDs down one side and can be stood on it own base incorporated into the opposite end.

I have a small led reading lamp that clips on a book. It will last for several hours before needing charged... if I read an hour or so per night, i charge it every 10 days or so. I also have a USB charged flashlight that lasts a very lo.g time.

These seem to hold a charge well, and have given us good service. We use them for camping and keep them around for power outages:
