INIU Power Bank, 100W 25000mAh PD Fast Charging Laptop Portable Charger for MacBook iPhone 16 15 14 Samsung S23 S22, White

P63 E1 13.5oz. 384g This arrived with a 46% charge. It does well with temperature. It barely gets warm in use (maybe 105-115f). It will accept about 85-91wh of charge The digital display is fairly inaccurate (can be 8-19% inaccurate) I am very satisfied with it. Test 1: recharging using a 65w Elecjet travel charger- 0:00 start. 63w rate. 0wh. 0%. 19.75v 3.2A 0:30 63w. 31.3wh. 36% 1:00 dropped to 32w (Elecjet charger overheats throttles). 60.5wh. 66% 1:30 32w. 77wh. 81% 1:50 dropped to 18w. 89wh. 91% 2:00 6w. 90.75wh. 92% 2:05 0w. 90.99wh. 100% So it took about 1:55 to recharge 0-100% using a throttling 65w travel charger Recharging using an Anker 100w desktop charger- 0:00 start. 63w. 0wh. 63w rate. 0:30 63w. 30.5wh. 35% 1:00 63w. 61.5wh. 68% 1:15 63w. 77.5wh. 84% 1:20 0w. 84.6wh. 100% So it recharges quite fast, in about 1:20 when you use a charger that can supply 65w, probably 20v, without overheating/throttling. The display read about 15% off; it displayed 84% when it was actually about 100%. It charges quite linearly, at a constant 63w. 30 minutes = 35%. 60 minutes = 73%. 1:15= 92% Simultaneously Recharging the Iniu, and a Note 10 , using a 100w RG100 charger: 0:00 0wh. 0% Iniu. 0% Note 10 0:30 35% Iniu 28.6wh. 50% Note 10 1:30 85.0wh 100% Iniu. 100% Note 10 So 1:30 to fully charge both devices. Simultaneously Recharging the Iniu, and a S24 Ultra, using a 100w RG100 charger: 0:00 0wh. 0% Iniu. 0% S24u. 0:30 27.5wh 58w 33% Iniu. 60% S24. 1:00 49wh 43w 58% Iniu. 96% S24. 1:30 74.6wh 57w 84%. 100% 1:45 88wh 37w 97% 1:57 89.7wh 9w 100% I believe the RG100 travel charger overheated, and throttled to about 38-45w on the Iniu for part of this test. Charging laptop with Iniu while using it 0:00 laptop 06%. Iniu 100% 0:30 60w rate. 30.5wh. 33% laptop. 68% Iniu 1:00 60w. 58.5wh 60% laptop. 35% Iniu 1:15 60w. 74wh. 74% 15% 1:20 55w. 79wh. 78% 06% 1:22 80.5wh 80% 01%, and shut off about a minute later So the Iniu was able to maintain a 60w charge rate. And added 80% charge to the LG Gram, plus the 1:22 of runtime Charging a (5 year old) Samsung Note 10 (powered off) It took about 1:25-1:40, which is typical. Charge 1: 100% > 82% 2: 82% > 62% 3: 62% > 41% 4: 41% > 19% 5: 19% > 0% And only charged the note to about 20% So it charged the Note 10 about 4.2 times. Charging a Samsung S24 Ultra Charge 1: 100% > 72% 2: 72% > 42% 3: 42% > 02% 4: 02% > 00% (only charged the s24u about 01%) This can only charge an S24 Ultra 3.0 times, which is inline with the advertised capacity. It took about 1:30-1:45 for each charge, which is typical. Each charge is about 23.5wh. The phone was off for 2 charges, and on with screen on for the 1. Detailed S24 Ultra charge: 0:00 100% Iniu. 0% S24U 0:10 92%. 5.4wh. 26% 0:20 89%. 9.1wh. 40% 0:30 85%. 12.6wh. 56% 0:40 81%. 15.97wh. 71% 0:50 77%. 19.4wh. 86% 1:00 74%. 21.5wh. 95% 1:10 73%. 22.6wh. 99% 1:30 72%. 23.4wh. 100% So the Iniu charges the S24 Ultra very quickly. About 75% charge in 45 minutes.

I keep this in my work bag to make sure I always have a way to keep my laptop (and phone) charged when there is no power outlet around. The large size is no different than carrying a power cord. So far my wife has actually used this to charge her laptop while on the road. It has worked great. I believe this has a low power mode to charge smaller gadgets that don't use QC/PD/PPS but since it's not on the item itself, I and other will probably forget it.
