Was nice

“Very slow to recharge and very slow to charge.”

It's good but cannot support fast charge on my Motorola RAZR 60 ultra.

I have a number of USB-based battery pack (battery-based chargers). Some are very small, lightweight, and thin and are really only designed for (often slow) charging of mobile phones and small electronic devices. Others are huge and designed to charge laptops up to full (along with anything and everything else) at a much faster charge rate. The challenge I set for myself was to find a battery pack that found a middle ground between those two extremes. Enter the Belkin Portable Charger, 3-Port Laptop Power Bank 20,000mAh. While it is not small (slightly larger than the palm of my hand but still easy to grasp), not lightweight (definitely has some heft to it, but not horrible), and not slim, it absolutely has the power output to charge mobile devices and portable gaming consoles at high/full speed, and can charge a laptop (M1/2/3/4-based MacBook Air) almost to full. Good number of ports for device charging (2xUSB-C + 1xUSB-A), good output wattage (65W PD max out of USB-C ports, 45W typical out of USB-C ports for mobile/portable devices, 18W QuickCharge out of USB-A), good display feedback on battery pack status, and easy and quick to recharge the battery pack. Until the next generation of battery cell power storage and output electronics hits the consumer market, this will be my go-to device for when I am out and about.

Das Produkt ist richtig gut und es lädt wirklich mit 45 W und es zeigt sogar an, wie lange es dauert, bis es entladen ist oder aufgeladen, würde ich definitiv empfehlen

Very good

I am delighted with this Belkin power bank. It is highly rated by The Guardian. I used it during a full day of botanising, taking countless photos, and it charged my phone to 100% twice - with 66% power still remaining. It charges quickly. It is a little on the heavy side but I guess that’s to be expected for a battery with this kind of capacity. Overall, I’m very pleased with my purchase.

中国での旅行目的で購入。３Ｃ規格表示があり検査も無事通過。充電速度も早く容量が多いので不足になる心配がないのも安心感があった。重さも２００００ｍA基準では軽いほうかと（Ankerとかに他と比べても）なので持ち歩く時にバックに入れてもかさ張ることもなく、重さをそれほど感じなくて街歩きの多い旅行には最適だった。結果、日本に帰っても通勤時の持ち歩き1番になり10000mAや20000mAの重い充電器は利用しなくなった。
