I’ve been using this portable charger from Oittm exclusively to charge my Apple Watch for the past several days and I’ve been pretty happy with it. It’s effective and efficient, but it’s not a perfect product. For topping off your Apple Watch battery on the go, it’s great. But if you plan to use it regularly, there are some things you should know.
Oittm’s small, lightweight portable charger is compatible with every Apple Watch model. The way this disc-shaped charger works is that first you must charge it up with a standard micro USB charging cable. This is not included in the package, but like many of you, I have some of these lying around the house. There are four LED lights along the side of the portable charger; when all four lights are on solidly, you’ll know it’s fully charged. The LED lights are bright, nearly bright enough to use as a nightlight. If you are someone who likes to sleep in darkness, you won’t want by your bedside. Something else to keep in mind is that this portable charger lies flat, so it is not intended for using the Apple Watch in Nightstand Mode.
You can use the Oittm portable charger while it’s plugged in, or you can put it on your keychain and use it on the go, unplugged. Either way, it charges your Apple Watch quickly and efficiently. I saw my Apple Watch battery go from about 50 percent up to 100 percent in just an hour or two as I got ready for bed. However, I left my watch on the portable charger unplugged overnight. The charger’s battery died and my Apple Watch started to lose power. When I woke up in the morning, my Apple Watch battery was down to 74 percent. So, my suggestion would be to use the portable charger unplugged only as a topping off solution. For a full charging session or overnight use, I would keep the charger plugged in. I had no problems obtaining and maintaining a full charge that way.
If you don’t mind using a micro USB cable for long charging sessions, this is a great portable charging solution. Keep it on your keychain for day-to-day topping off, but be prepared to bring that cable for more extensive travel and charging.
