Batteries/Phone chargers: Make sure the "wh" are labeled

Dear All,
I had a portable USB battery that I had travelled with through airports all over (including China for the previous 3+ years).
My battery, along with those of several other passengers, were confiscated at security in Shenzhen airport two months ago because the "wh" was not listed on the battery.

According to the security staff, the newest regulations from this year state that the "wh" of less than 100wh must be labeled on the battery charger, or security can take it from you.

So, check your battery for proper labeling before you travel. Each airport is different...you may encounter no trouble.
