Do I need a 90 Watt power adapter to charge this battery ?The retain capacity is dropping with the 65 Watt power cable.

I don't think its power retain capaity because of 65 Watt power adapter, it will just take more time to charge. Where as 90 Watt adapter can charge it fast. If you feel it is because of 65 watt adapter try 90 watt adapter before purchasing it. I hope this will help...

For what it's worth, I'm using the original adapter that came with the laptop and having no issues.

I think 65w is pretty standard, but if you are not sure, the 90w is compatible with the 65w according to the description on Amazon, so spend the extra couple of dollars and get the 90w. I have an ASUS and I got the 65w.

I don't think the charger cares about the battery's capacity (Ah). Think of the battery like a bucket and a garden hose like the charger. The bucket can be any size, the hose will just take longer to fill it up. I don't know why you would want to use a significantly smaller/larger battery though - just get an appropriately sized UPS. Here's more info about the 850: http://www.cyberpowersystems.com/spec-sheets/CyberPower-datasheet-CP850PFCLCD.pdf

I reviewed the specs on a retailers web site. It mentioned this particular model adapter. See below. Power Supply Optional Adapter (PA-3C/PA-130), or batteries (Six "AA" size, LR6 or Ni-MH rechargable batteries) Power Consumption 8W (with Optional PA-130) Hope this helps.

Yes dave I've always used the power adapter. I've never tried it without. Sits on my desktop plugged into my battery backup.

I bought a 16 watt with an internal battery storage which the one you are looking at doesn't. Charges my I phone 5

Depends what you're charging from and what kind of power output it has. Remember this is 13000mAh. It's a large battery. If you're charging from the wall try a different wall connector. If you're charging USB you have to consider the amp output of that port. And if you're using solar power you gotta consider output of that as well.

by all means get the larger one. It will charge your laptop faster. It will also have less likelihood of being a subpar device.the only difference between getting the bigger and smaller ones would be that's a smaller one is somewhat lighter but really not enough to make a difference especially when you consider performance.I work on machines as my profession. I almost never see a burnt out 90 watt power supply . . . most of the burnt out power supplies that I see are 65 watt power supplies. Good luck!

Good Morning, In a quick check of D620 power requirements(19.5vdc@4.62a), I would say that you should not use this charger. It is rated at only 65w vise the 90w requirement for the computer. Would look for another charger that has the correct rating. Best luck Andy

I use the dell 90 watt charger that came with my laptop and don't have any issues.

The adapter on the one I received states that it is only 250mAh. Not sure that is really enough to power anything......

Correct. In fact, if you go to the Lenovo website you can find that *they* offer a 90W Ultraslim AC/DC power supply as a recommended accessory.

There is no adapter, you are buying only the "base" that comes with a cable, but no power adapter you need to provide your own

Check your sleek book specs, if it says 65W, then you should have no problems.

I am using a HiTec 44165 X1 AC/DC charger. It balances, allows you to set storage voltage, save program; and it doesn't need a separate power supply in order to plug into the wall. Almost all of the other chargers need a separate power supply, which while inexpensive ($8-15) still needs to be sourced. I've used it for that exact same battery; works fine.

I only had a Samsung S9 laptop for a short duration, using the stock AC adapter and the travel adapter. Both are 40W

Power capacity is much less for that connection. Mine is not handy just now, but I believe the rating is on the machine.
