The best top dollar power bank
Small and compact ...supports samsung s23 super fast charging 2.0 with appropriate cable wattage and protocols Easy to recharge ...went up to 100 watts charging coz I don't have any 140 w charger ...am sure it can go higher if correct charger is used with proper cable Build quality is top notch ...sleek ...elegant Extra light feature is a bonus ..its dimmable in 3 steps Has its own display which shows wattage input and output draw . Shows percentage of battery left Only con : its expensive and can't be carried on a flight !

Heavier but overall better than a 150Whr V-mount battery for powering cameras
150Whr for 14K that supposedly lasts much longer (lifespan not runtime) than a traditional lithium ion cells in a comparable V mount battery... unique item.

大変良い!!
小型で大容量。パススルー対応で3000サイクル。 耐久性は分かりません。突然壊れる可能性もあるでしょう。 でもそれは一部の悪意ある商品以外にはあり得ることなので、仕方ない事です。 とにかく、今はスタンディングデスクに下記構成で使っていて、コンセント外して移動するときも常に電源が供給できるので助かっています。 この構成で消費100Wくらいなので、AC100V給電しなくてもしばらく持ちます。 ①スタンディングデスク ②テーブルタップ+USBアダプタ+「当該商品」 ③ノートPC(type-c電源供給) ④27インチ_モバイルモニタ(type-c電源供給)

Empfehlenswert
Als Teil meines mobilen Setups versorgt die Powerbank alle meine Geräte (ca 20w) für gute 6 Std mit Strom. Für mich der ideale Formfaktor und dank LiFe Technik habe ich auch keinen Stress mit vielen Zyklen. Ich kanns uneingeschränkt empfehlen.

Huge capacity, amazingly compact, great value
This is probably my favorite new UGreen product in a long while. The capacity is enormous but is packaged in a compact, attractive form factor. The light is a useful feature when camping and I love that it supports fast charging. I have an Anker 548 battery bank that used to be my go-to camping battery with 60,000 mAh but it’s twice the size and has a maximum output per port of 30 watts. While this battery doesn’t boast the same capacity, it’s less than half the size in footprint but still offers 80% of the capacity and boasts quicker charging speeds and a more attractive screen. The only feature this lacks over the Anker is a solar charging port, which I honestly never used on the Anker due to impracticality. My only gripe with this UGreen battery is that the input port is on the front of the device. I would have personally preferred it to be on the back, but that’s a nitpick.

Performance issues
It doesn't charge on 140W, even from original charger 200w with original cable 240w from Ugreen. It doesn't charge my 90w mobile above 30w. Meanwhile build quality is solid, as usual for Ugreen.

Power bank migliore che ci sia
Costa 100€ ma li vale tutti: sono stato in campeggio 4 giorni senza corrente e ho caricato 4 volte al 100% il mio telefono e quello dei miei 2 amici, e sono arrivato a casa con ancora il 40% di batteria nel powerbank. Top.
