GOODaaa Solar Power Bank 30000mAh,Built-in Type-C&Micro&iOS 3 Cables Portable Quick Charger External Battery Pack 4 Output Dual Input, LED Flashlight&SOS (Gray), OD-IMO2

Pros: Long life - the first time I used it, it was 5 days before I had to recharge it, that included several hours where two phones were being charged at the same time; multiple options for charging, wireless works well; other than solar charging, everything was as advertisedCons: Bulky, won't fit nicely in a pocket; I sat it out in the sun for several hours on an empty charge and the battery didn't recharge at all

What a fantastic piece of technology, this battery pack has it and does it all. I’m not trying to exaggerate; I am just very excited to have purchased a device that is so versatile and handy.Battery pack – CheckIPX5 rating – CheckEmergency flashlight – CheckSolar panel – CheckQi charger – CheckQC 3.0 fast-charger – CheckPD USB Type-C port for in and out charging – CheckMultiple USB/micro/Type-C ports – CheckHook for carabiner – CheckLED charging indicators – CheckTiny little compass – CheckOK, I’ll admit it’s a little on the hefty side at just over a pound (16.4 oz.), but it does so much and feels so well-made that I’m willing to compromise on the weight. Usually I have a battery pack in the car for emergencies, just like you’d carry a flashlight and flares. When I go backpacking I take a different battery pack that can be hooked onto my pack, and of course at home/work I have Qi chargers. Now imagine combining all those devices into one, and that’s what you get here.All of the specs on this pack are great. I have verified that it can deliver fast charging voltage to a compatible device, and with a proper charger, it can also recharge at fast-charging voltage. Repeated use of the fast-charging capabilities will of course lower the lifespan of the internal battery (FYI). One thing to keep in mind, is that even in optimal conditions, that is the sun light hitting it at the perfect angle, and assuming no power-conversion loss, the solar panel would take a little over 70 hours to fully charge the battery pack. I mention it just to manage expectations. Those limitations are not unique to this pack, but rather inherent in the available solar-technology at this point.The pack has a ruggedized finish, and the ports have a rubber cover to keep the IPX5 water/dust intrusion rating. The Qi charger works great, and it too delivers fast-charging voltage. To me, everything else like the flashlight and compass are just gravy and only add bonus points to an already very capable charger/battery-pack. This device has quickly gone to the top of the list of my favorite gadgets.

I will break down why this is the best portable charger available below.1. It has tons of battery life and fast charging. a) I have been able to charge 3 devices on low percentages with less than half of the available life. b) it can be used to charge a macbook if needed2. It is durable a) I don't plan on throwing this charger around, but I know I could of I wanted to. I would be fine attaching this outside of my bag if it weren't for the possibility of thieves -_-3. It is solar powered (if in direct sunlight) a) its environmentally friendly option is a big plus in my book. I'd probably use it when camping4. It has WIRELESS CHARGING!! a) it can charge through the case pretty well (if your case is thin enough) never have you felt more posh than setting down your phone on a brick and hearing your charging jingle. ^o^5. This company GOODAAA has great customer service!

I'm writing this from Grenada, WI Latitude 12.0. The sun does not get much more direct than here. I've left this thing out in the sun all day, and it does not charge at all. If you charge it up with a power cable, it does hold quite a bit of energy and can charge phones over and over. Another fault is that the wireless charging is a bit flaky. If your phone has a cover, it will charge for a moment and then the red light (foreign object detected) light will flash and it will stop charging. You have to try quite a few times and re-orient your phone to get it to reliably wirelessly charge.Other than that, Mrs Lincoln, how did you enjoy the play?

Great product. It can take a beating at keep it coming. The charging power is amazing. It does have the ability to charge multiple devices by way of the wireless charger and cable. Only issue is that whatever is using the cable will charge slower. Fast charging of course will run the battery life fairly quickly. Is say about 4 good charges and you may need to charge the charger. The flashlight is brought enough. It's not exactly a spot light but you'll be able to see whatever your pointing it at.Overall I have nothing negative to say about this device. Would definitely recommend.

This power bank has the biggest capacity among all of my power banks. It is declared to have 20000mAh which should charge over 10 iphones without charge itself.Based on apple's site, its iphone X has Non-removable Li-Ion 2716 mAh battery (10.35 Wh) and can be carhged at 15W to reach 50% in 30 minutes. This power bank output can reach 18W fast charge mode. it has other features too like anti-slip texture and waterproff for outdoor activies.It is fully covered by a rugged rubber protection and the corner is reinforcecd. I used it for one time and it charged my iphone 7 from out of batter to full in 50 minutes. It is a really good gadget for outdoor activites lovers.18w Solar power bank can charge my Mac Pro laptop.

We have been sitting at the beach all day in full sunlight, even having the solar panels facing directly toward the sun and nothing happens. We bought this for our emergency pack but if the sun won’t charge it on the sunniest of days, what good is it. I wish I would have tested the solar charging when I first bought this so that I could return it.

Would have given the product 5 stars if the cover over the USB for more secure
