Feeke Solar-Charger-Power-Bank - 36800mAh Portable Charger,QC3.0 Fast Charger Dual USB Port Built-in Led Flashlight and Compass for All Cell Phone and Electronic Devices (Orange)

Starting with con's:• Slow charging output when using both ports.• C port is input only for charging the bank, not an output.• Bought three, one was a lemon. Of course easy replacements with Amazon solve this though.Pro's:• Immense storage (36.7k mAh)• Incredibly cost effective (cheaper than banks half the capacity)• Very small form factor for the capacity• *Can be used as a power HUB, both charging and decharging simultaneously. Or, It may be pass-thru and charge, I have yet to verify if any charge rate declines when plugged input & output in tandem.Below were my initial impressions.Immense [storage], incredibly cost effective if it functions anything close to how it appears.Tiny (comparatively), smaller than 20k mAh and 30k mAh competitors.Major point: all appearances indicate that it is capable of functioning as a power hub, meaning it can charge and decharge simultaneously, or perhaps charge and pass-thru if not decharging while recharging.This is huge in my opinion, because I've spent five times as much for 2/3rd the capacity and no hub functionality in a heavier form factor.Yet to do any extensive testing, though I'm already ecstatic with first impressions.

I've had this device for a couple of years. I just recently found out that not all ports go both ways. Some of the ports are 'in' and some are 'out'. I always charged it with solar, because we camp on the beach often. I plugged it in to charge it and must've plugged it into the wrong port because it didn't charge. Then I went to use it with my new phone and the middle port was an 'in' and not an 'out' port. Meaning it takes the charge IN to charge the device. Anyway, make sure you know which ports are for what and then it works fine. Flashlight is bright enough and works well.

I carried this with me for most of my trip in Florida, and it wouldn't even charge my phone fully. The flashlight doesn't work, and it dies quickly. It's an okay budget option, but not if you don't want to buy another one out of frustration.

We have multiples of this product. We used them to charge phones, run USB lights in a power outage, charge blue tooth speakers, and even run indoor security cameras. These are awesome. The solar is a bit weak but could work in a pinch. I do recommend them !!!This battery was totally dead when it arrived. I had to "shock" it to get it to charge. Once I did, it charged and appears to be fine. It's holding the charge so far. Of 5 of this style, this is the first one arriving totally discharged.

At an advertised 36800mAh capacity, this device should provide my new Google Pixel 7 with approximately seven full charges without requiring a recharge itself. Before using the device at all, I charged it fully per instructions. Then I charged my Pixel 7 one full charge off of this power bank - from 3% to 99%. A couple of days later (with the power bank in sunlight during the day), with the Pixel down to 8%, I tried it again. It only got to 43% before the power bank died. That's less than one-and-a-half full charges.The advertised capacity of this device is severely overrated. I will return this device at my next opportunity. I rarely say do not buy something based on my own experience - but if you're interested primarily in a device-charging power bank that works according to specs, and you don't care about a uselessly slow solar charging feature or an integrated flashlight, do not waste your money purchasing this device.UPDATE: Since my initial review, the seller has sent me three emails offering me compensation, via gift cards, etc., to delete my negative (honest) review. They're even willing to compensate me more than I paid for the device ($21.19). To be fair, I've changed the headline from "Woefully Pathetic Underperformer" to "Extreme Underperformer". Perhaps this title is slightly less hyperbolic. I didn't change the star rating, since I still believe this product is a rip-off.I'm currently testing a competitor's power bank using the same method (I'll provide a review, with specs, for this device once the test is complete). Yes, I paid almost 2.5x as much for this other device, but it has already provided my Pixel 7 three full (<10% - >95%), fast charges, and I estimate it will provide ~one more full charge. Do the math. Do you want to pay ~$21 for a flashlight with a solar charger and don't care about actual device-charging performance? Buy this Feeke device. Do you want a power bank that honestly reports charging/capacity specs, and you don't care about peripheral bells and whistles like solar charging and a flashlight? Look elsewhere.

Good power supply can charge up my phone 2 or 3 times before needing a to recharge. The compass works well and seems rugged. The carabineer is a bit weak but will hold the charger but is plastic not metal an easy fix if you carry it on a backpack. The led indicator are a quick reference and accurate. The led flashlights are a bonus and could come in handy . All in all a good value.
