Solves The Problem Of not Always Finding An Outlet

For everyone who has ever had the problem of finding an outlet to plug a charger into this is the solution.
It is also the solution if the power is ever out for a long period of time.
This charger solved my problem of finding a outlet when traveling. Took it on a train trip to Riverside CA on Wednesday and used it to keep my iPhone charged.
Was able to use the iPhone to take many pictures and videos without having to worry about keeping the iPhone charged.

I've had one for several months now and so far it worked
well. I mostly use it to charge my watch (using slow charge mode) it only takes about an hour and half and lasts for more than 5 charges before it goes low enough to need charging
itself. Glad I got it.

I had just gone through a horrible storm where I lost power and had no way to charge my phone, pad, or lamp. This energizer saves the day for the next storm and is exactly what I need. A great buy.

Got very warm, along with phone when charging. Didn’t charge from both slots.

Hi Jtechguy, Sorry to hear about the heating and charging issue. Wireless and fast charging can cause some warmth, but if it feels excessive or if both ports aren’t working as expected, that’s not normal. Please stop using the product and contact Energizer support for assistance or replacement:

Convenient rapid charging of cell phone in car or on the go. Only downside is that it does not magnetically hold the phone in place while charging
