Great box for the price!
This is really an update, the aimtom 300 for this price it's one heck of a great solar generator. Having the 4 USB's in AC out let also woutlet also a 12 V outlet is absolutely awesome. Having additional 5.5 mm DC plug outlets is awesome for all those additional those additional smaller appliances that you might have can use. If a charge is pretty fast from AAC outlet, it also has the input for solar which works absolutely fine. It comes with the standard MC4 connector cable and any 100 W panel will work fine, I have a 175 W panel and it charges the aim Tom pretty quick , I don't have so much input ability but as I have noticed it takes about 2 to 3 hours and it's fully charged and that's from being almost empty. I have been using this in Tom consistently for the last 2 months on a daily basis, and it is performed beyond my expectations. One of the drawbacks is the LED light is not backlit so it's really hard to see in any sort of light, you need to take it inside to be able to really read it well or have it in a really dark area to be able to see clearly. This is not an issue 1 inside in light, it's just sunlight washes everything out pretty strongly. The display doesn't show what's going in-and-out unless if you're using the AC outlet and it actually shows the water that's going out which is a bonus gives you an idea on how long your aim time's gonna work if you have something plugged in period it does have 4 individual buttons to turn USB on the DC out on the 12 V DC out on or the on are the AC outlet, which is really handy if you only need to use one thing. Of the display shows what's on pretty well So from one of the 4 buttons that are on, it takes a couple of seconds to figure out but once you do it's really quite informative. I bought it at a $194 I see that it's a 167 now, may and buy this thing it's definitely worth it. And so you know my basic use for it is keeping a 10" fan DC 5.5 mm connector on all night and a couple of USB lights, and to keep my phone charged throughout the night while I'm using it. That can do this for about 2 to 3 days before it needs a recharge, absolutely satisfied with this product.

This battery seems to cover all of the bases for me (AIMTOM SPS-300)
I originally purchased the Aimtom SPS-300 to use as a battery to run a CPAP machine while on a camping trip. I charged up the unit when it arrived and tested it out. It ran the CPAP for 3 straight nights without a recharge. Very nice. Since then, the battery has sat in my closet as a backup in case of a power failure since our camping adventures have been cut off by the pandemic. Last week, though, we finally took off for a week of tent camping in the Northern California Redwoods. The scenery and hiking was spectacular and we are super pleased with the performance of the Aimtom SPS-300. We used the AC output to power our new self inflating Queen Mattress for the tent. Yeah, we are getting older and sleeping on the ground sucks. We also kept our phones charged (amazingly, we did have cell service in the campground). We kept our Kindles and night lights charged as well as powered the CPAP. The big unknown was using the 12V port on our Ford Explorer to charge the Aimtom back up. No worries! I left the Aimtom plugged in inside the car and it was easily topped up each day. The Aimtom worked flawlessly for everything we asked it to do. Now we are home and the Aimtom is back in the closet until next years camping season. If I could ding it on anything, it is that it drains down in the closet within a couple of months and I have to remember to charge it up or it won't be much use to me for the CPAP if we have a power failure. Other than that, I have no complaints. It's a great little unit and I would buy it again.

A month later and I'm still impressed by just how small and light this battery is.
After using this battery pretty rigorously for the last month and a half, I can say it's my new favorite portable battery. I find myself out in the field away from reliable power quite often while shooting photos and this power bank is perfect for recharging my device batteries, driving my telescope, or powering my laptop. I'm also happy to report that the built-in inverter is a true sine wave power supply. Most importantly, though, this battery is incredibly light small and light, even for its capacity class. I included a photo of my other lithium battery for comparison and you can see just how much smaller this one is. To be fair, the old battery does have more capacity, but even then, the Aimtom battery is head and shoulders above my old one in terms of size and weight. For comparison, my old battery has 1.5x the capacity, but it weights 2.37x the Aimtom, is 2.44x larger, and cost 2.31x as much! I'll include all the stats below if you're particularly curious about the numbers, but the first words out of my mouth when I lifted it out of the box were "holy sh... this thing is small!"This is now the second Aimtom product I own and I'm happy to say that they make quality products across the board. I'd recommend this battery for anyone who needs major juice on the go. The 280Whr battery will get you at least 3 full charges on a laptop or 20+ (!!) charges on a cell phone. Not to mention the wide variety of ports means you should be able to connect practically any device you own.As promised, here are the stats from my battery comparison:Aimtom 280Whr Power Station -Weight: 3120g (self-measured)Dimensions: 7.4" x 5.5" x 5.9" (self-measured)Grams per watt hour: 11.1 (calculated)Watt hours per cubic inch: 1.16 (calculated)$ per watt hour (at the time of this writing): $0.925 (calculated)Competitor's 428Whr Power Station -Weight: 7394g (2.37x heavier)Dimensions: 11.3" x 6.9" x 7.5" (2.44x larger volumetrically)Grams per watt hour: 17.27 (55% heavier per watt hour)Watt hours per cubic inch: 0.73 (37% less power per cubic inch)$ per watt hour (at the time of this writing): $1.40 (51% (!) more expensive per watt hour)
