Top 5 Positive Customer Reviews for 19v power bank
Received the item in about 20 days. Thanks Seller Hong Kong century electronic - wholesale Technology Co., Ltd. and Aliexpress for fast shipping. The item was received in very good packing. The multi voltage power bank is an ideal power back for any router of 12V or 19V or 9V etc. Working cool with my Router. Quality of the item seems to be good. In this price it is very good deal. Recommended.
Received the items in good and working condition. However, the USB port cannot change Samsung Phone like S7, S7 Edge, S8, S8+, Note 8 and even S9, S9+. I don't have non-Samsung phone to test. The normal DC output is working fine. Miix 520 able to use 21V and I can use the power bank as external power up to 3 hours using recycle 18650 battery from notebook which tested rating at 2Ah each. Btw, the power bank will drain 33% of power in a month if not use. Therefore needs to recharge it before use after unused for 2 months.
Good battery, everything works as advertised. It can deliver enough power to charge my Asus chi300 at 19V. So I am very satified with the purchase. But two things could still be improved: It only deliveres 1 A at 5 V (better would be 2 A). And a 5V charging port would be very useful to charge it with any USB charger. Now you need an extra charger.
IT’S A GREAT PRODUCT AND THE BEST EVIDENCE OF MY SATISFACTION IS IN ME PURCHASING TWO OF THEM. IT’S A MARVELOUS, MULTIFUNCTIONAL SOURCE OF POWER AT A VARIETY OF VOLTAGE SETTINGS FROM 5V UP TO 21V. YOU CAN POWER ANYTHING FROM LOW POWERED PHONES AND TABLETS, THROUGH BIKE LIGHTS, POWERFUL MOBILE LOUDSPEAKERS TO NOTEBOOKS. YET SELLER PLEASE PROVIDE THE USER WITH A DETAILED DESCRIPTION OF HOW TO SET THE REQUIRED VOLTAGE. IF AN AC POWERED BIKE LAMP TAKES UP TO 8.4V AND YOU USE THIS DEVICE WITHOUT KNOWING, YOU MAY WELL END UP WITH 21V AND YOUR DEVICE BURNT. I LOST MY FENIX BTR20 BIKE LAMP IN THIS WAY. ALSO YOU CAN’T USE PROTECTED 18650s WITH THIS DEVICE AS THEY ARE TOO LONG AND WILL BREAK THE CASE. ONLY 18650s WITHOUT PROTECTION FIT IN. PLEASE SELLER, LET PEOPLE KNOW THESE THINGS AND THEY WILL LOVE YOU AND THIS GREAT PRODUCT.
