SinKeu Transportable Energy Financial institution with AC Outlet, 88.8Wh Transportable Laptop computer Charger, Transportable Energy Station Outside Turbines Transportable for Dwelling Backup Outside Emergency

Issues but excellent customers service
I bought the portable battery to be able to travel on a plane (less than 100 watts by plane) and recharge my satellite phone on the 3 prongs AC with my solar panels. It worked at home when I tried it for testing even if I was not able to reach 100% but 99%.
Second try was on a remote place when I needed the battery to be charged during the day. The battery charged to 86% max but the display was loosing battery very fast without anything plugged on it till 0%. I tried then to charge it with the electric cable but same. The product is not charging anymore after 2 uses. Unfortunately I travelled abroad and I can’t return it because I leave for more than 30 days.
Thankfully, the customer support was very reactive, they reached to me very quick to help me with my battery. They offered to send me a new one in exchange of the non working battery which I appreciate a lot.

Survival in Alaska! Superb Customer Service in Exchange of Power Bank
I have been quite a fan of Jackery solar units and power banks, but unfortunately this company never manufactured a compact solar panel + power bank system that could easily fit in a backpack and be transported to remote regions, especially with luggage weight restrictions!
While browsing on Amazon, I happened to stumble upon Sinkeu’s products and made a digital-life-changing purchase that helped me survive part of a salmon season in the boonies of Alaska this past summer! I used the Sinkeu power bank mostly for my laptop computer, cell phone, and recharging small electronics such as usb workman lights and a compact radio. This Sinkeu package is superb for remote field work, with extremely limited access to electricity (an occasional generator); the sun was my best friend, as it managed to charge my power bank in between 4-6 hours, depending on the angle of the sun.
When I returned from Alaska to California, my powerbank suddenly stopped working and I wasn’t able to use the AC outlet for my laptop. I called in Amazon customer service, and the technicians attempted to troubleshoot the situation. We could not resolve the problem, and Amazon support guided me into contacting Sinkeu. I began working with a very friendly support agent named Olivia, and we managed to swap out my broken power bank with a new one that is working and in fully functional use! I presently have my power bank and solar unit in the trunk of my car, where I am able to whip out these electronics whenever I am in remote places, or the local Starbucks stiffs their customers of outlets and access to electricity for keeping my laptop and cell phone charged.
Thank you Sinkeu for your fantastic and innovative product! I feel your company truly is a pioneer in manufacturing compact, solar-based, remote power supply systems that can easily fit in anyone’s backpack! I am truly grateful for your helping me with an exchange so I continue to smoothly engage in remote field work!

Great portable laptop charger
I bought this charger to charge my laptop while going on a road trip and it worked so well. It was able to charge both my laptop and my son’s ipad before dying. Money well spent.

Have used it irregularly for about three weeks as a portable battery for some small tools (soldering iron, tiny air compressor, etc), and no problems so far. It provides a decent amount of charge both for AC and DC output, is simple to use, and the screen is nice and clear. I’ve charged the bank twice so far, and didn’t experience any of the issues mentioned by some other reviews: I left it plugged in overnight both times, and found no burning smells or other scariness in the morning. (Protip: Make sure to use the charger that comes with the bank, a normal 12V wall wart won’t cut it.) In addition to the wall charger, the bank also comes with two adapters for car cigarette lighter ports and a crappy bag to stuff everything into. None are game changers for me, but nice to have I guess!
My one major complaint is the plastic casing, which seems kinda flimsy. It isn’t the worst I’ve seen from an Amazon gadget, but I wouldn’t trust it to protect the bank from falling >2 inches onto a hard surface. I’d wager that the charging jank for some of these units were due to a hard knock during transport, but who knows. The AC plug is also very tight, it’s a little looser now that I’ve used it a few times, but be prepared for some elbow grease the first time in. Last minor gripe is that the On button is very easy to accidentally press, the bank has snappy auto-off so it shouldn’t cause a bunch of wasted drain, but I’d store it in a little bag (like the aforementioned crappy one) to prevent any surprise shorts.
Assuming it holds up, I think this is a decent portable battery for throwing into a glove compartment for emergencies, or a backpack for light duty camping (or my own weird hobby use). However, I’d avoid using this for any kind of heavy-duty work where it’d be jostled around a lot, or for people with butterfingers and hardwood floors 😄

It was broken so I had to send it back, was hoping another one would go on sale again so I could purchase it, it didn’t, so I bought a different one! 🙁

Good charger works good.
