GRECELL LiFePO4 Portable Power Station 240W (153.6WH), 100W PD Dual Battery, Portable Power Bank with Built-in Stand for Outdoor, Camping, Travel(No Wall Charger

I read quite a few negative reviews on this product that I wanted to clear up as a veteran power station user. First if you do need an inverter to provide 120AC this is not the product. Second this power station says clearly it does not come with a power supply to charge it. It does come with a 100 watt USB A cable but you must provide the power charger. Third the USB A port marked input can be used as an output but it may not provide 100 watts. In testing it did provide 80 watt out put to charge a Mac Laptop and the directions say 100watt Max either direction input or output. Now on to this product. This portable charging station is fabulous for charging phones, bluetooth electronic devices, headphones, watches, cameras, laptops, I could go on and on. It charged easily with a 65 watt USB C charger that I had and purchased from Amazon. You can also purchase a 100 watt USB C charger on Amazon for $14 dollars. Weight is only 5 lbs and its the best non inverter portable power station I have used. The units light will light up any room for hours with very light battery drain. I also have other power stations that are much heavier and have inverters like the EBL 330 but as said for camping or just power black outs where you will need to charge the items I mention this is my favorite power station. UPDATE: The USB-C port mark C1 on the input panel can be used for charging and output for heavier current devices like laptops. If you don't have a USB-C charging input on your laptop you can buy them on Amazon here: https://www.amazon.com/dp/B0DP9ZKF3J?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 I purchased one for my ASUS computer and it works perfectly with my Grecell T-200 power station. They have them for all different laptops.

Works fine. Output: no issues so far. Input: charges acceptably off of 30W, 60W, and 100W sources. Only complaint so far - the built-in LED light doesn't stay up and there is something rattling around inside. I suspect the two are related, like maybe an internal piece that locks the light in place broke off in assembly or shipping. Update: popped it open and sure enough, one of the screws that held the light broke off and was loose inside with plastic pieces. Removed it along with the other screw which was about to break off. Light is now only able to lock in one position but no more rattling loose screws and plastic bits.

It has a useful form factor and the batteries are good, charges quickly. However I'm taking a star off because the DC port on mine is nonfunctional and i didn't test this right away and so the versatility of the item is significantly less. Edit: Decided to order another because it was on sale hoping for a different outcome. Turns out the new unit would not charge at all from the box. So these units are junk imo. I would stay away from these.

I have a handful power stations with various capacity from 34Wh to 1kWh - 3 Ecoflow and a few unknown brands such as this Grecell. I actually do not need any more power station but I'm attracted by the flexible light on this unit, which none of my other power stations offer. Another reason is the sales price that makes the $/Wh value good. Whenever I receive a new power station, first thing I do is to measure the actual output capacity. I'll return the unit if the manufacturer overstate the capacity excessively. For this Grecell T200: 1. Capacity: Rated at 153.6Wh , actual output (measured with USB-C current meter) is 134Wh, which is 87% of rated capacity. Due to charging loss, anything above 85% is considered good 2. Weight: The listed weight is 4.5lb, but the actual measure weight is just over 5.0lb . Beware if you are looking for a feather weight unit, this one is not. 3. Charging time: I read several reviewers complained 10hr charge time, I think they do not realize that there are all kind of USB charger, if you take a charger comes with your phone ( which is typically 20W or less), it'll take forever to charge this unit. If you take a 100W USB-C PD charger it'll be 5 times faster. I used a 100W USB-PD charging brick in my test, and this unit pulled about 92W all the way from 0 to 75% and then dropped to 56W, total time to charge from zero to 100% was 2hr even, consuming 166.2Wh ( including some charging loss) . If you charge from 50%, the unit may only pull 56W (even if you use a 100W charger) and it'll probably still take 2 hours to charge from 50%-100% Overall I am satisfy with this unit, mainly because the LED light and the price.

It is a great value for the money. The cigarette lighter is able to run my electric refrigerator and my portable heated lunch box. The max out on the USB are 18 watts. The only reason for a 4 star is that the light bar is flimsy were as it drops, its not compatible of holding lights in a certain angle but that is not the reason I bought it for so I don't care. If your buying it the light and looking for it stay in one spot its not going to work. Other than its good battery bank.
