TSBar Rugged 20000 18W

Purchased in 2020 as my primary back-up battery, primarily for mobile phones and laptop (in a pinch).Kept in my work backpack and taken on all work trips to backup my phone on planes and hotel rooms where there was no (or not easily accessible) power outlets. Have used at home walking around the neighborhood, carrying with my iPhone when I was on long calls when power was running out (in part due to Bluetooth ear buds). It's form factor is slightly larger than an iPhone 14 and can be held together in the same hand. Have charged multiple phones at the same time, has plenty of capacity to charge one phone multiple times.Accompanied me to the World's Toughest Mudder, surviving mud, water and a Ramen noodle soup spill, charging my and my pit crew's devices over the 24 hours.Charges fast, have used all ports for charging (USB, USB-C) at one point or another.Only downsides:- a bit heavy (expected)- lasted ~4 years (did not know what exactly to expect)

Battery life is great! Great for camping trips or if you are using a GoPro it will keep it charged for HOURS while recording,

The power bank seemed like a great one for going camping off the grid for four days. I bought it specifically for that reason. I figured I could charge my Samsung S9 about 4-5 times with it.It arrived a few days before I was going on my trip. It was half way charged, and I charged my phone with it, and later tested the light on it to make sure it was functioning. It was so I plugged it in overnight to get it fully charged up. The next morning it was, so I disconnected it and checked to make sure the light worked again and it did.I went on my trip and later that evening my phone was down to 20% battery life, so I hooked it up to the power bank. Immediately it started charging so I felt confident I'd have no problems. I checked my phone an hour later and the battery life indicator on my phone said it was up to 60%. I checked it again an hour later and it was still at 60%. I checked the charger and it was completely dead. Luckily for me, I also brought along an Anker and Dark Energy power bank.When I returned home from my trip, I plugged the power bank in to the wall and nothing happened. It wouldn't charge up at all. I left it plugged in for two days and still nothing. It is completely dead.

This rugged charger pack is exactly what I needed! I regularly take all-day fishing trips, and needed a charger pack that I didn't have to worry about getting wet when it rained. This one has fulfilled that need, and the flashlight is an awesome added bonus! I've used it multiple times for light while I'm rigging up my boat before launching first thing in the morning.When I purchase products like this one, I do my best to use them uninhibited to make sure that I don't need to return them. I've dropped this thing, thrown it into the boat, let it sit through a rainstorm, and yet it still looks brand new and works perfectly.I've seen other reviews mentioning having trouble charging it. In my experience, these devices need to be charged by legit micro usb chargers, not just any USB port that you have handy. I used the charging block that came with my Samsung galaxy S10+, and it actually charged to full capacity quicker than my other power packs.On one full charge, I have been able to charge my Galaxy S10+ 6 times before having to recharge this device. That being said, I didn't let it die completely. I recharged it once it hit 1 orange light on the battery indicator.Overall, I would most definitely recommend this device for anyone who spends a lot of time outdoors and needs to keep a power source available. I have a wife and 4 kids at home, and I know it brings them comfort that I'll always be able to get in touch with them.

I’ve used and enjoyed this charger since September 2023. Stored it in a backpack and it hasn’t been dropped or wet. Now suddenly today it went completely dead.I’m disappointed and would like a replacement.

Reliable power bank to take on adventures. Has great charging capability. Have used it for long hikes and to charge multiple phones on our walking adventures. I have purchased other techsmarter power banks as well. Contacted company about an issue I had and they were quick to respond and provided excellent customer service.

I keep the battery at work for when I’m playing on my phone avoiding any type of physical labor. I love it but my boss often throws rock at me. Charges my phone faster than I wish my Honda Civic would drive. Only problem I have is the flashlight. You tap once, turns on, tap again, lowers the light, tap again, strobe light, then you tap 40 times trying to turn the strobe light off but you get a seizure while doing it. Coworkers will press the button to test the battery just to find out that their impending doom is to a non stop strobe they can’t turn off. I followed the instruction and all but the 2-3 clicks to turn that light off never works. You just sit and pray.

I bought this a few months ago and let me tell you I’ve been using this to power my GoPro/phone for all my fishing trip and then last month it decided to take a dump on me and die out and there’s no power, no source, no charging, so I contact customer service and I was still within the warranty, and then send me a new one right away so five star to customer service.
