Pinty Portable Uninterrupted Power Supply 300W, UPS Battery Backup, Rechargeable Generator Power Source with AC Inverter, USB, DC 12V Outputs for Outdoors and Indoors (300W, Yellow)

Got this for few weeks now, its work fine, charge my all electronic devices (phone x 2, computer x 2) + 2 lights for all night without problem. It’s small and light weight enough to carry it around. It’s good for camping or extra power source when emergency.

UPDATE:The first one we got worked well, but didn't charge up all the way. We returned that one and re-ordered. The second one charged to 100% and worked well on our camping trip to charge phones and run laptops. Note: I do not believe this thing would handle anything over 300 watts. Still a little irritated that they did not respond to my email.FIRST REVIEW:We thought this product was good and did what it said. The main problem is that it never charged all the way full.The closest it got was 75%. The part that was REALLY irritating was when I emailed their customer service (it says they will respond in one business day) I did not get a response. We have returned this one and are trying the same one again. Pinty...this is your last chance.... If the new one charges to at least 95-100%, I will be satisfied, otherwise, I am done with you. Thanks.

Ran for 12 hours with my CPAP machine. Beeped when the charge was low and let me know. Compact and works for my needs for emergency power.

This is the worse back up power unit I have ever purchased and I have purchased 5 to date. It took so long to arrive I had requested a refund and received it 2 weeks before it finally came. After 2 weeks of use the AC portion stopped working first, then the phone charger ports, then it refuses to charge at all. A very DISAPPOINTING item. Don't buy one. Waste of money.

-- IF you only charge from the Mains/AC it works great.-- DC charging is unregulated and potentially a fire hazard.If you charge from DC, Cigarette adapter, or Solar, you can NOT exceed 12.0 VDC (more specifically do not exceed 5A or 60 Watts MAX) input without risk of too much current draw and overheating of the wiring, and the included cigarette adapter does not appear to be fused.Realize that a car is nominally 12.0 VDC, but can be closer to 13.8VDC if fully charged, around around 14.2 VDC with the engine running.The same thing goes for various solar panels, and it's not uncommon to have an open circuit voltage or around 21 VDC coming from a "12 volt" solar panel.IF you are technically skilled, you could add a voltage regulator before the DC Input that limits to 12.0 VDC and no more than 5 Amps, and that would keep things much safer.I was able to run a 120VAC @100W 20" high velocity fan for over 90 minutes before it gave a low battery alarm , then shut itself off safely. So it's runtime is within the specs given and *ALL* inverters should be derated by 85% due to efficiency loss.If you plug in a 120VAC device that's more than it's rated 300 Watts, it will give an alarm and safely shut itself off.The 12 VDC output jacks are regulated and use a DC5521 (5.5 x 2.1 mm) jack to connect devices to.The 2.4A USB ports were able to fast charge my phone which was nicely unexpected.It will fully charge within 6 hours from 120VAC.---IF you only ever plan on charging from 120VAC, it works great. The 12VDC charging is questionable, especially since the included cigarette adapter is NOT fused. and became excessively too hot and pulled more than 10A. which could potentially damage the unit. The DC Input is also not fused.The light is bright and works well. it's lightweight, compact, use REAL switches (instead of "soft switches") which is a nice thing to have as there is less drain on the system when in storage.If you use this and stay within it's specs, it's actually a nice little unit. But that it doesn't accept actual vehicle voltage (13.8 to 14.2VDC) without over heating the cables, and is NOT fused, is a no go for my main intended usage which is to be able to charge from car or solar.

Too late to return. The AC still works. The USB must have a fault.

Bought this to provide backup power for my modem and router during power outages. When installed as power through device, it worked as intended and kept my internet going during several power outages lasting multiple hours. Only functional downside for me was there was a few second delay in it switching to battery output after an outage, causing my modem/router to reset resulting in a couple minutes of internet downtime. This was an annoyance but I could live with it given that power did resume automatically without me needing to do anything.HOWEVER, biggest negative is it stopped holding a charge after exactly one year, would have expected several years of life at least. Wouldn't buy another of this brand.

300W I power it solar every day. Most days given good sun I get 100% power. It was a great product dirt cheap and worth every penny.
