myChargePortable Charger Waterproof USB C Power Bank Adventure, Rugged Outdoor External Battery Pack Backup (6700 mAh (Blue))

Have nothing to compare it to but it served the purpose during the long flight👍

This power pack is long lasting and is waterproof dust, dirt, and drop protection.I like this because I can hang it off a carabiner and charge my cameras.The downside is that it is a little heavy, and the carabiner that it came with broke in a week.

I really enjoyed this powerbank, but the clip broke off in a matter of days from ordering. There is no other handle that is safe to use so without the clip it came with, it just was not good to carry around. The charge was good but seem to run out fast. You cannot charge it and use it at the same time. This charger does wonderful with solar panels, but I do not recommend just leaving on the solar panels for a long time and forgetting about it. Charge it just enough to get a full charge and remove it.

Very reliable source of power. I bought two for my hunt in Alaska. I got 3-1/2 full charges on my iPhone per charger.I recharged them on a portable solar panel.Waterproof, well built and reliable.

I recently used this on a backpacking trip. i used for 3 days charging 2 devices and it was still at 90%

Just bought it a month or two ago and now it doesn't charge anymore to charge something else. Aint even worth being a paper weight.

Would not charge. Directions are 1 page without clear help. The usb-c did nothing. The usb-a's gave the following message to 3 different phones: "high powered usb device connected. cannot access to this device. Connected device needs external power supply." It actually started draining the phones battery. The powerbank was fully charged prior to use. Sending back as there are too many other reputable name brands at this price that are proven reliable.

I got this battery as part of my charging solution for a long term backpacking trip well off the grid. A shakedown camp showed that it will work well. It accepted charging from a Nomad 5 cell even on an overcast day when many batteries would put themselves in safe mode and not accept charging. The carabiner made it teally easy to clip to my pack.This 6700 mah battery can charge my Samsung S9+ twice on a single charge as long as I turned the phone off while charging (which is what I do while camping with the phone, anyway).My only concern is that the charging ports are at the same end of the battery as the carabiner. I'm not sure how waterproof the battery is when the chargeport cover is off while charging. This could cause issues if caught in an unexpected rain shower while hiking on the trail because the open ports could be directly exposed to rain.All-in-all, though, I am satisfied with this battery.
